We are for some time now trying to find a solution for server prerendering of SPA, specifically Angular4, for the purpose of SEO.
We have come to try and use aspnetcore-angular2-universal, which seems to be the perfect solution, however, we encounter problems deploying the published build to a local IIS server.
We have posted an issue regarding the problem on the issues page at which can be found here:
https://github.com/MarkPieszak/aspnetcore-angular2-universal/issues/491
We have followed the instruction under "Getting started" & "Deploy" (which can be found here: https://github.com/MarkPieszak/aspnetcore-angular2-universal) exactly but the error still exist.
The support is unresponsive on issues and thus we are posting also here.
The problem is (as mention in the issue linked here) that we get the following error:
Which indicates a problem with the web.config file. However the webconfig file is exactly as supplied in the starter project and seems also legit.
I should mention that building and running the project using npm build:prod and dotnet run works and we can lunch an in memory application from Visual Studio Code, however when taking the published folder to an IIS folder the error occurs.
Any help will be appreciated.
Did you installed .NET Core Windows Server Hosting bundle?
Check if AspNetCoreModule listed in IIS => Modules. Sometimes it not installed properly during #1, even if there was "Succeeded" at all steps. In that case I just removing it via Program & Features, and reinstalling it then.
Once I saw that error when manually copied web.config from sources over the publish folder. Problem is that original web.config contains placeholders like %LAUNCHER_PATH% and %LAUNCHER_ARGS%, which turns to appropriate values (dotnet and .\YourApp.dll for instance) during dotnet publish
Aperantly there were incompebilities between angular5 & universal in serverside.
The https://github.com/MarkPieszak/aspnetcore-angular2-universal seed was downgraded to using angular4.3 instead of 5. When we updated seed, the problem was solved.
About a week ago I noticed strange behavior with my install of Visual Studio 2013 Pro. Creating new projects always results in missing references to EntityFramework and most of the Microsoft.* components. I had reinstalled .NET 4.5 in repair mode around that time but can't recall if this problem happened before or after that install.
As it stands, I can no longer create a functioning project. I have an existing project I'm working on that will compile and run without issue, but creating any new projects (which I need for spike solutions etc) is no longer possible until this is fixed.
Screenshots follow. These are all from creating a new MVC project with all defaults accepted.

Reference paths are empty (this was mentioned in another answer that did not directly address my specific question, so I'm including it)
Regedit showing .NET versions installed
Even though I have "repaired" .NET 4.5 it appears from regedit that I only have up to .NET 4 installed? Am I reading that correctly?
Also, due to network restrictions I cannot download packages from Nuget automatically -- I have to download them manually from a laptop off-network and then sneakernet them over to install. The network physically blocks all connections to Nuget, github, etc.
If allowing VS to connect to Nuget is the only viable option then I have considered installing VS on the laptop, creating the project there and installing all necessary dependencies, and then moving the project folder over to the restricted computer and continuing from there. But I don't know if that is a solution to this problem or not.
Any advice appreciated, thanks.

It's almost like they don't want you to be productive.
Anyway the project templates (which you seem to be talking about) reference specific NuGet packages. Packages by default are stored relative to your solution.
Place a nuget.config in your disk's root (or any point into your projects directory, if you keep them organized like C:\Dev\Visual Studio\Projects, then each of those subfolders will be file) and point in that file to a shared package directory on your development machine. Here you can dump all packages you require.
i have to fight against a strange issue in my company. we have 2 .net 2.0 (old, i know) apps, which start with an .asmx-file. the code-behind calls a c#-file, which includes a include abcd directive, whereby abcd originates from a 3rd-party company.
one app is in test and it works fine. the identical one is in production and fails with the error Could not load file or assembly 'abcd.dll' or one of its dependencies. The specified module could not be found.
when i look in the related web.config-files, none of them includes a pointer to abcd.dll, which i first do not understand in the context of the productive environment, where everything works. secondly when i look inside the \bin-folder, i see the related assembly/dll. again: this is identical in both systems.
the only difference of both systems is the fact that visual studio 2.0 (does this really exist?) is available on the test system.
please note: i am aware that assemblies have to be added via solution explorer in visual studio too. but i cannot do this as such an installation is not allowed here. but again: in web.config on the test server no reference can be found in the related web.config and everythings works fine.
so my question is: how to get this thing working in productive env?
thanks in advance
You may want to run Dependency Walker (depends.exe) http://www.dependencywalker.com/ and point it at to detect if any dependencies are missing.
I'd also look in the GAC (C:\Windows\assembly) to see if there are any related differences there.
Also, compare IIS setting on the two machines.
When using Visual Studio 2008, when I "Publish Web Site", the application builds correctly, but then I get a "Publish failed" message:
What possible reasons are there for this, and how can I prevent it?
I had the same issue. Nightmare to identify the problem, because the logs and outputs show no errors or failures. I simply get "Build: 39 succeeded" and "Publish: 1 failed".
I resolved the problem by systematically removing all NuGet packages one at a time (and removing code that references it) until I identified the offending one.
This takes a LONG time!
However, the answer for me was Microsoft.Net.Compilers.
No idea how I ended up with that in my project, but as soon as I removed that package, everything publishes fine again.
Edit - For what it's worth, this problem occurs on VS 2008, 2012 and 2015 but does not occur on 2017.
You can try this:
Perform precompilation against the web application.
Clear the target directory(virtual directory in IIS or physical file
folder) and deploy all the files (of the web application) into the target
directory.
In the output window you can check at which stage does the publish website
operation fail. For example, at the first stage, if there are some error
which will only occur at precompilation, that will cause the stage 1 fail.
Or some times if the target directory has something configured incorrectly.
Such as the IIS virtual dir is not set to the correct ASP.NET version or
some old files are locked and prevent them from being cleared. Mostly,
publish failed will be caused by IIS side configuration issue such as
authentication setting....

You can open the output window by pressing Ctrl+W, O.
Sometimes it's because you need to be running VS as Administrator to be able to write to the target directory.
Check the Output messages, they should help you solve the problem
I had to copy project to C:\a\ and than publish. I suspect problems with long path. Strange, but worked for me.
The conclusion is: Try another VS edition and see if that does it.
Here is what did it for me.
I have VS 2013 Pro and Visual Studio 2015 Community. I sort of use one or another to work on my MVC project and all was fine. Then all of the sudden VS 2013 could not publish though it would build just fine. There was no erros other than some silly ...code is not returned from all paths...
So when I open it in VS 2017 - it published the same project just fine. I am suspecting a compiling issue - because that was the stage it would fail at.
Hope that helps you save a bit of time.
Not sure if this happens in different versions of Visual Studio, but at least in 2015 Professional Edition, the problem arises when we try to update all Nuget packages from the solution using the Packages Manager.
As pointed out by #SimonGoldstone the issue is caused by the package "Microsoft.Net.Compilers". By default, the package gets added to the solution while creating a new web application. The default version 1.0.0 does not introduce any problems. I was able to keep testing with latest versions until 2.4.0 and everything works fine, but from 2.6.0 henceforth is when it all starts. If an update is strictly required, I would recommend updating the aforementioned package until version 2.4.0. After doing some research, seems that some bugs on later versions than 2.4.0 are introduced and not fixed on the long term. What is curious though, is how this problem gets included on Nuget with no basic quality control checkpoint.
There are many proposed solutions for this. I think they are overcomplicating the issue.
I found the following worked for me:
Locate the obj(Release or Debug) folder in your solution
Inside the Release or Debug folder delete the CONTENTS of the 'AspnetCompileMerge' folder
Now try and publish.
Make sure you empty the target folder (manually) before publishing. Sometimes vs cant delete a file which will result in a failed publish
After trying a Rebuild, having other Projects in my Solution able to publish correctly, and changing my publish location to the C: drive (locally attached) instead of pushing to a mapped network drive, I was still having an issue where the only error output said:
========== Build: 5 succeeded, 0 failed, 0 up-to-date, 0 skipped ==========
========== Publish: 0 succeeded, 1 failed, 0 skipped ==========
My solution is targeting x86, but I think during a Git Merge, this project had it's profile switched to Any CPU. After creating an x86 profile for the project and having it match the target of the publish goal and of the active solution configuration, I was able to successfully publish again.
Check Project BIn directory. there must be a DLL of your page or control. which has to be recreated during publish. So exclude it or remove it
I ran into this same problem today and it was due to the Thumbs.db file that was created when I opened my images folder to look for an image. I deleted the file and the project deployed successfully. Hope this helps someone else in the same situation.
Delete publish profile and create another one . Worked for me
In my case, I was publishing to a directory in a mapped network drive, but the Output panel/window was indicating that the location didn't exist. The path was correct, and the drive was fully accessible. The problem resolved itself when I re-set the path to publish to in Visual Studio by using the ... button.
With me it was simple - the dist folder was locked. I unlocked it by an unlocker and the publishing resumed.
I have several user controls that are registered in the web.config, and have a ClassName in the .ascx file header. For normal builds everything works fine, but with a publish those class names were not recognized anymore. At some point I found out that the errors were not in my regular code files, but in copies in a temp directory for publishing.
I had "Precompile during publishing" turned on (to be found under Settings > File Publish Options). Turning that option off worked for me.
I had the same issue with VS2017 with a website project. Build worked, but publish gave me an error:
Error CS0012: The type 'System.Net.Http.HttpMessageHandler' is defined in an assembly that is not referenced. You must add a reference to assembly 'System.Net.Http, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'.
All my projects already had a reference to System.Net.Http so it was really confusing.
To fix it, I had to copy System.Net.Http.dll into my website project / bin folder so publish could find it and copy it to my web host. I found System.Net.Http.dll by looking at another project's references (a class library), then System.Net.Http.dll Properties, and seeing the path (C:\Program Files(x86)\Reference Assemblies\Microsoft\Framework.NetFramework\v4.6\System.Net.Http.dll).
i know iam late but i think it should use for someone whos searching for this query.
just uninstall all your nuget pakages , then clean and rebuilt solution ,
now click on publish , sure it works and u will see publishing starts and works correctly now
If any one had changed the version of the project file and related framework. then this type of issue happened.
please go to "C:\Program Files (x86)\Microsoft Visual Studio\2019\Professional\MSBuild\Microsoft\VisualStudio\v16.0\Web" location for visual studio published and build setting -> edit -> comment the force copy of all file section.
I had one file that was not found. I had copied in a png file to replace a jpg in the content folder , same name except filetype extension.
Project built fine, but refused to build and publish . changed extension of file so it could find that file name and it worked - no errors amazing 1 thing wrong and everything else is an error.
The case for me was that Visual Studio was not signed in to Azure, but provided no indication of that. I edited the publish profile, clicked "Validate Connection" then clicked "Save" and then it worked.
I was working on a feature branch, which was failing. Switched to Master Branch, deleted the feature one and created another one. It worked.
What caused my issue was a little different, but has similarities to some of the reasons stated above.
I managed to trash my local copy of a given application and did a GIT hard reset to get the most recent from the repository in question. This in turn, wiped out the web.config file (which was not stored in the GIT repository for various reasons).
This cause configuration information for various NuGet packages to be "lost" (since it was stored in web.config).
Fortunately, I had "backed up" the web.config, so once I figured out it was not out there (a migration failed because I was unable to connect to the database), I was able to replace it.
Tried the publish again, after fixing the web.config, and everything worked perfectly.
If you are opting for the "Delete all existing files prior to publish" in the publish web dialog box, then make sure that the Visual Studio is started with Admin rights. Right click the Visual Studio and click Run as Administrator. Hope this helps.
This one’s a head scratcher. Here’s the deal.
While deploying a beta copy of an ASP.NET application built with Delphi 2007 for .NET to a test server I encountered an odd problem. The application was unable to start because it could not load the correct version of an ADO.NET data provider that I was using.
Only by including a version of the old assembly in the bin directory would the application run. However, I don’t want to be tied to this older .NET data provider, so I am determined to find a solution to this problem.
I originally compiled the project with the .net data provider assembly used as Copy Local, which should have caused Delphi to use a copy of that version of the assembly that I selected when I added it to the References folder in the Project Manager. The actual assembly that I selected was version 9.10.2.0, and that is the version of the assembly that appears in the bin directory, along with the application. However, at runtime the application was trying to bind to an earlier version of the same assembly, 9.0.2.7.
(Actually, this problem occurs whether or not I use the GAC version of Copy Local, so I don’t think this is the issue.)
While investigating this problem I created a new project, and added a reference to the 9.10.2.0 assembly. Still, both the .NET 2.0 Configuration Utility and Reflector showed that the application compiled with a reference to the 9.0.2.7 assembly.
Inspecting the GAC I saw that both 9.0.2.7 and 9.10.2.0 versions were registered. Attempting to remove the 9.0.2.7 version fails, since that version of the provider was still referencing the assembly in the GAC.
I went into the registry and manually removed all references to the 9.0.2.7 provider. I then was able to delete it from the GAC. This didn’t change anything. Removing the assembly from an existing application and then adding the 9.10.2.0 version back, then compiling, still resulted in the wrong assembly information being inserted into the application. As before, creating a new application that referenced the 9.10.2.0 assembly didn’t work, as a reference to 9.0.2.7 was still being inserted into the executable.
I’ve checked the Delphi library search path. I also removed every instance of the old assembly files from the machine altogether (including from the ASP.NET Temporary Files directory). I still got the problem. I tried using Issam Ali’s AppManifest utility to manually adjust the manifest, but apparently it does not support ASP.NET applications in Delphi 2007 for .NET.
So, the GAC no longer contains references to 9.0.2.7, there are no references to it in the registry, there are no paths to the old provider directory in the project or Delphi options dialogs, the old provider assembly is not on the file system, and 9.0.2.7 does not appear in any of the project files. Nor does it appear in web.config, machine.config, or any other file I checked. Nonetheless, Delphi insists on using this version of the assembly anytime I reference the 9.10.2.0 version of the assembly. (Yes, I restarted Delphi, and also restarted the Virtual Machine in which this development was being performed.)
Even after uninstalling the 9.10.2.0 data provider (the older one was already uninstalled), and reinstalling it, adding the data provider reference to an application results in the runtime application attempting to load the old provider (even though no reference to the old provider apparently remains in the system).
I’ve tried other solutions (which are worth mentioning here), but none worked. Anybody seen this? I am going to continue working on this problem, but I’d love to hear suggestions. I just can’t get Delphi to stop inserting the old assembly information into the project.
For grins I’m including the error log from the failure. This log essentially duplicates the information I get from the fusion log. This log is from one of the simple apps I created after removing the 9.0.2.7 assembly from the GAC. Notice that it’s looking for the old version of the provider from the outset.

This has gone on so long that the comments that I added to LanceSC's answer are no longer showing. But I do thing this is an interesting item that I want to address.
Here's my last two comments to LanceSC
The installation that exhibited this behavior is in a VM that is no longer functioning. Another developer I know experienced this same problem. The solution was to abandon the installation. I feel that something in the installer of the particular version of this .NET data provider left some strange artifact that produced the problem. It does not happen with any other build of this data provider. I am no longer pursuing an answer to this question.
Spoke too soon. A colleague of mine, today (March 5, 2010), encountered this same error, with a slightly earlier version of this same .NET data provider (9.0.2.1). He is now in the same position I was. He cannot run his application with any version of the data provider, save the old one. That assembly was being used as a local copy, and the old version is not in the gac. Using his machine, we ran the run MSBuild with the verbose option. The build worked fine with no errors. Nonetheless, the compile application failed to run, having failed to find the old version of the provider.
Summary
My colleague resigned himself to reinstalling Delphi 2007 (fortunately, he was working in a VM, and had a second VM with Delphi 2007 in which the offending .NET data provider had never been installed. This was also my tactic.
At this point, I have concluded that this problem is not solvable. Nonetheless, I am leaving this question open for another week or so. If no feasible solution is proposed in the next few weeks, I will close this question.
In the meantime, I have asked my colleague to preserve the VM with the misbehaving provider, in order to test any solution or investigation that is proposed.
Delphi 2007 uses MSBuild to perform the actual builds; however, the code in their product that syncs changes between the IDE and MSBuild is very brittle. My suspicion is that the build files are out of sync with the IDE. An easy way to update them is as follow:
Open your registry editor go to
HKEY_LOCAL_MACHINE\SOFTWARE\Borland\BDS\5.0\Globals
Change the value of ForceEnvOptionsUpdate to 1.
Open the RAD Studio IDE.
In order to confirm my suspicion you need to locate the files that Delphi.NET feeds to MSBuild. They are located somewhere under the current user's profile. You may also want to look at options in the Delphi help to have it do a verbose MSBuild output.
Have you tried grep'ing the Delphi and .NET framework directories for 9.0.2.7 to see if it is in a config file somewhere?
Something like:
grep -d 9\.0\.2\.7 *.xml
Other places you might search:
search the project files for 9.0.2.7
registry search for 9.0.2.7, and a search using the public token
If this app uses the BDP you might also search the BDP config files
I ran into something very much like this, and it drove me absolutely up the wall for days. I had a reference to Oracle.DataAccess.dll that was resolutely stuck pointing at an old version, regardless of what was in the GAC, in the search path, etc. No amount of restarts of modifications to the .dproj files would ever work.
What I eventually found was that the offending piece that was holding on to the old reference was the generated Oracle.DataAccess.dcpil in the C:\Users\Public\documents\rad studio\5.0\dcp directory.
It was over a year old - whatever the case was, Delphi did not want to write over it.
Once I deleted it, Delphi merrily created another one, and sure enough, it now points to the assembly I want it to.
Ugh, frustrating!
