Problem removing codeSubDirectories elements in sub-application - asp.net

I have an ASP.NET application with a <codeSubDirectories> section in web.config. My main project is in VB.NET but I have a CSCode subdirectory under App_Code written in C#. Now for every new sub application I create I have to create a CSCode folder under App_Code. Microsoft's documentation says there is a <clear /> element but I get an error when I add it to the sub application's web.config file. What's going on?

Found it. Apparently Microsoft never got around the actually coding the <clear /> element for <codeSubDirectories>. The online MSDN Documentation mentions this in the Community Content section.
As a workaround I'm going to move the CSCode into a separate DLL.

If you didnt have the source code, you can create all subdirectories inside your App_Code subapplication, even with no content. Code works great, in the most cases.

Private web.config for each developer

Consider a group of developers working on an ASP.net web application. Each developer would like to have a private version of the web.config.
By "private" I mean that a developer can freely change the file to suit their dev/test needs at any given moment, without it affecting other team members and without ending up in source control.
How can one go about achieving this with Visual Studio 2015?
My closest solution so far is to have a "private" Solution Configuration with a matching Web.config Transformation file ("web.private.config") that's excluded from source control.
But this is not a satisfactory solution because:
a. The transformation is not run automatically when debugging (with F5). The developers need to remember to run it manually.
b. The result of the transformation ends up in the main "web.config" file which is, naturally, included in source control.
We had a very similar problem but only needed personalized versions of the <appSettings> section in Web.config.
In this situation the inclusion of an external file through configSource turned out to be problematic, as this attribute completely replaces the <appSettings>-node. So there remains no way to keep global key/values AND personal key/values for all developers. The whole section is completely replaced by the included private file.
What we need is both global and private <appSettings>. The solution we found was the file attribute. It allows to merge Web.config settings with settings from an additional file.
We ended up with a construct like this one:
<!-- Web.config with global appSettings) -->
...
<appSettings file="Web.PERSONAL.config">
<add key="BaseUrl" value="https://projectname.dev.local" />
...
</appSettings>
...
­
<!-- Web.PERSONAL.config with personal appSettings -->
<?xml version="1.0" encoding="utf-8"?>
<appSettings >
<add key="EmailSmtpUser" value="my.name#my.domain.com" />
<add key="EmailSmtpPwd" value="***" />
</appSettings >
If you put identical keys in both files, the Web.PERSONAL.config version will overwrite the Web.config version.
The file Web.PERSONAL.config must be excluded from Git through .gitignore .
Keep in mind:
While configSource works for ALL nodes in Web.config, the file attribute is restricted to <appSettings>.
Have web.config include an external file (via configSource) and add that file to .gitignore
The correct answer is to host your local development site in a separate location from your Visual Studio solution. You can then use publish profiles to publish changes to that location and web.config transforms to maintain a separate local config for each developer. Each developer would use a different publish profile which transforms the web.config with their own transform and deploys the transformed web.config to the publish location. You can then attach a debugger to the published site using Visual Studio's Debug > Attach To Process option.
I think there is a lot of value in standardising dev environments so that one can just download the solution and run it.
Custom, long term/permanent, developer specific configs will sooner or later lead to a subtle bug that will be tricky to find.
My solution to your problem would be to find out the reason(s) why permanent individual configs are needed and have a look if these environment specific differences can be eliminated.

Owin error with ASP.NET MVC application

I have an ASP.NET application that runs fine on my local machine. I just uploaded it to a server using web deploy. I'm getting the following error when I try to view the site:
The following errors occurred while attempting to load the app.
- The OwinStartup attribute discovered in assembly 'Gators3' referencing startup type 'Gators3.Startup' conflicts with the attribute in assembly 'MyFirstProject2' referencing startup type 'MyFirstProject2.Startup' because they have the same FriendlyName ''. Remove or rename one of the attributes, or reference the desired type directly.
To disable OWIN startup discovery, add the appSetting owin:AutomaticAppStartup with a value of "false" in your web.config.
To specify the OWIN startup Assembly, Class, or Method, add the appSetting owin:AppStartup with the fully qualified startup class or configuration method name in your web.config.
I tried searching the entire solution for the string "MyFirstProject2" but did not come up with anything. The message gives a couple of suggestions, but none of them mean anything to me. I don't know how to "Remove or rename one of the attributes, or reference the desired type directly," and I don't see a place in the web.config to "add the appSetting owin:AppStartup with the fully qualified startup class or configuration method name in your web.config."
I found this, but am not quite sure how to implement it. I also did find [assembly: OwinStartupAttribute(typeof(Gators3.Startup))] in my Startup.cs, but not sure what the right thing to do there is either.
The problem is that the Gators3.dll and MyFirstProject2.dll are in the same folder (I guess it is bin folder on your server) and both are using Owin middleware. If you do not need MyFirstProject2.dll then the easiest way would be to delete that assembly. If you need it, but without Owin - add following line to Web.config/app.config in your MyFirstProject2 project:
<add key="owin:AutomaticAppStartup" value="False" />
If you need to use Owin for two projects configure friendly names for both of them.
Gators3 project:
Change Owin startup attribute to something like:
attribute [assembly: OwinStartupAttribute("GatorsConfig", typeof(Gators3.Startup))]
And add following line to Web.config within appSettings section:
<add key="owin:appStartup" value="GatorsConfig" />
MyFirstProject2 project:
Change Owin startup attribute to something
like:
attribute [assembly: OwinStartupAttribute("MyFirstProject2Config", typeof(MyFirstProject2.Startup))]
And add following line to Web.config within appSettings section:
<add key="owin:appStartup" value="MyFirstProject2Config" />
I had the same issue : removing everything in the /bin folder and rebuilding the solution alone worked for me. But it could be combined with renaming your assembly attribute at the top of the startupclass, giving it a Firendly name which will help to differentiate both the startup files.
[assembly: OwinStartup("MyFriendlyNameForProject1",typeof(MyProject.Startup))]
Clear your bin folder and obj folder.Rebuild the project again and run :)
Also, if you publish a solution to Azure:
1) right click and select Publish.
2) go to Settings and expand the "File Publish Options"
3) select "Remove additional files at destination"
4) Publish
Worked for me, after deleting the files from obj and bin Folder.
Delete anything that says 'MyFirstProject2' from your bin folder and rebuild the solution, It will work.
Happens when you reference (by mistake?) a project with owin startup inside another project with owin startup. Fix - delete the reference, bin, obj folders and rebuild.
I had the same problem and i added the following tag on web config:
<appSettings>
<add key="owin:AutomaticAppStartup" value="false" />
</appSettings>
This is what I have done:
Since I have 3 projects in one solution, I had to open all bin folder of each project and delete all files there.
Build each project one by one.
Build the whole solution.
Problem solves on my part.
Remove all files in your 'bin' folder and rebuild.
Delete files Bin, Build each project one by one.
Deleted everything in the bin folder, including the roslyn folder then published, and everything worked fine.
Remove old built data in temporary files, in the following path
C:\Users\[user]\AppData\Local\Temp\Temporary ASP.NET Files\vs
In my case, I was referencing one project in the other accidentally, which is why I was getting this error after removing the one accidentally added in the main project solved the problem.

Can I use ASP.NET Web Pages without deploying the "bin" folder?

I am creating a very simple site that was originally just a bunch of HTML / CSS files. Then I needed to add a little bit of server-side logic so I thought I'd use ASP.NET Web Pages as they sound like a suitable solution.
So I changed index.html to index.cshtml, added the code I needed and I though that would be it (I also added this basic web.config file:
<configuration>
<system.web>
<compilation debug="true" targetFramework="4.0" />
</system.web>
</configuration>
However, launching this on local IIS Express yielded this error:
Could not determine which version of ASP.NET Web Pages to use.
In order to use this site, specify a version in the site’s web.config file. For more information, see the following article on the Microsoft support site: http://go.microsoft.com/fwlink/?LinkId=254126
So I added this to my web.config:
<appSettings >
<add key="webPages:Version" value="2.0" />
</appSettings >
Now the site starts but handles UTF-8 really weirdly - although all the HTTP headers, file encodings and meta tags are correctly set to UTF-8, my national characters display incorrectly. I found this question: Do I need web.config for non-ASCII characters? but it didn't really solve my problem.
I though, what can be wrong with my setup? When I create a new site in WebMatrix and copy my files over to it, it all works fine, even without specifying the Web Pages version in web.config. And the only difference I can see is the presence of bin folder in the WebMatrix-generated project.
So the question is, do I need to have the bin folder as part of my source files too? I don't really feel like checking 1.5MB worth of binary files into Git should be necessary just to add one dynamic line in my index.cshtml but maybe that's how it is?
Thanks for either confirming this or showing me some better way.
ASP.NET WebPages requires a BOM on UTF-8 pages or it won't read the page as UTF-8. And if it doesn't do that, it won't output a UTF-8 encoded page.
This isn't an ASP.NET issue, but rather a WebPages issue. WebPages processes the real page, and it doesn't interpret the html to know that it should be UTF-8. The only way it knows is by looking for a BOM.

Mono WebForms: Setting default page to run when starting debugging

is it possible to set a default page to run when starting debugging? In Visual Studio you can set the default page either through the context menu in Solution Explorer or in the project properties. I did not find something like that in MonoDevelop.
When I am starting debugging the browser will always navigate to the root of the application.
http://localhost:8080
Because there is no default page set in XSP for this application I get an error and always have to correct it manually.
http://localhost:8080/home.aspx
Thanks for your help.
I found a solution. I did not find the xsp.exe.config but it also works when you add the setting either globally in machine.config (residing in /etc/mono/[version]) or by creating a web.config file in your applications root. The values are comma separated.
<appSettings>
<add key="MonoServerDefaultIndexFiles" value="Home.aspx, home.aspx" />
</appSettings>
The help page http://www.mono-project.com/Config does not tell you that a appSettings section is allowed, but I think that the documentation is just incomplete. For example appSettings are used here http://www.mono-project.com/ASP.NET_Settings_Mapping#Inhibiting_the_settings_mapping too.

Referencing code in App_Code from web.config

I have a type in my App_Code folder from a Web Site project that I want to refer to in Web.config. The type attribute is requiring me to put in an assembly name. The internets is failing me with what to put in for the assembly.
Specifically in,
<system.web>
<webServices>
<soapExtensionReflectorTypes>
<add type="MyType, $App_Code$" />
</soapExtensionReflectorTypes>
</webServices>
</system.web>
What do I put in $App_Code$ to make it compile? I've tried _ _ code, App _code, App _Code (Markdown is failing here: those type names don't have spaces in them)
OK, I found the answer on some obscure MSDN forum: you can't do that in a Web Site project for system.web/webservices/soapExtensionReflectorTypes. Only a Web Application Project will suffice.
I found a work around for a Web Site project. I moved the type out of the App_Code folder and put it in a new class library, compiled and added to the bin directory.
Now the web.config section finds the type through
<soapExtensionReflectorTypes>
<add type="MyNamespace.MyType, FileTitleOfLibrary"/>
</soapExtensionReflectorTypes>
The second argument is the filename of the library without the file extension.
