I am working on a .NET project that I publish on Microsoft Azure.
When I publish the app, I see some termination in log files. In particular, the first one is:
Application 'D:\home\site\wwwroot\' was recycled after detecting app_offline.htm.
I have no app_offline.htm in my directory in Visual Studio.
So I am publishing the application, and it immediately terminates, hence stops working.
How do I fix this?
Please check your .csproj in Visual Studio, because it probably holds the setting you're looking for. One of the properties you can set for Web Deploy (MSDeploy) is EnableMSDeployAppOffline, which seems to default to true.
This is causing the app_offline.htm file to be created. Set the EnableMsDeployAppOffline value to false if you don't want to take the app offline when publishing.
Also, taken from Visual Studio publish profiles (.pubxml) for ASP.NET Core app deployment - Compute project items.
When an ASP.NET Core project references Microsoft.NET.Sdk.Web in the project file, an app_offline.htm file is placed at the root of the web app directory. When the file is present, the ASP.NET Core Module gracefully shuts down the app and serves the app_offline.htm file during the deployment.
I've searched all over SO and Google but have not been able to clear my confusion about this. It seems like a very basic question but am just not clear about this.
It is advised everywhere that you should have debug="false" on your production websites because this can have a significant performance impact as debug symbols are loaded when the site is compiled. Agreed - and that is what I have on the production site.
Our website (not a web application) is a .Net 4.0 website that I pre-compile on VS 2012 (and previously on VS 2010) using the 'Publish Website' command. The site is pre-compiled to be "UI updateable".
My question is: If I pre-compile my site, then how does it matter what the production debug mode is set to? I assume debug symbols are not loaded and code optimization is already done in the pre-compiled DLLs. To test this, I've tried switching the debug mode before pre-compilation and it has no effect whatsoever on the size of the DLLs in the bin folder.
This post here: Publish in debug mode but compiler removes code inside #if debug seems to indicate the the debug mode has an effect on publishing the site as the author wants debug info in the DLLs.
Am I missing something?
Let me take a stab on your question, hoping i got you correctly.
Starting from Visual Studio 2010, a new concept called Config. Transforms. Those are files that help you customize the web.config files during deployment package generation which is triggered during 'Publish'
Those transforms are tied to the build configurations. So you will have one for debug called web.debug.config, and so on.
When you click publish or generate your package by any means, VS checks the current configuration, debug for example, to generate the right web.config.
What are the types of deployment we have in asp.net?
Till now what I am doing?
I use to publish my website in any folder than copy paste the compiled file to the inetpub folder [where my website is configured with the IIS]. I am not sure what kind of deployment this is, is it XCOPY? But I am not using any command line tool.
So you have the following options
xcopy deployment
Compile your asp.net application and copy all the files to your server. You can do this by using FTP or shared directories. (Or anything else to transfer files.)
WebDeploy
You have the possibility to deploy your asp.net webpage directly form your Visual Studio. If you go to "Build" and you choose "Publish Web". To be able to to do this you have to configure your server before. But this works automatically after you have set up everything. It's very handy since your deployment becomes easy to rebuild.

Web Setup - Installer
Visual Studio provide also the option to build an installer. This works like installing usual software on your windows computer with the installer wizard. (See the link)
http://weblogs.asp.net/scottgu/archive/2007/06/15/tip-trick-creating-packaged-asp-net-setup-programs-with-vs-2005.aspx
Manage multiple server
There is also a way of managing the deployment of multiple servers. It seems to be a bit more complicated but could be interesting for professionals. (Check out on Google Microsoft Web Farm Framework 2.0
To answer your question: yes, what you are using is called xcopy deployment. Even though you do not type xcopy . ... it is still a 'plain copy' and therefore called xcopy deployment.
I know you can copy a Website intact to the server and have it run normally (security and compilation time aside).
What about the projects that are in the solution? [whose dll's are copied to the bin when built]. Is there a way to copy the projects' code files to the server as well?
My goal is to be able to debug [by modifying code in the project if needed] directly on the server without having to install an IDE [or keep building on dev machine and copying over dlls]. I can debug/modify the website files, but not the projects.
EDIT: to clarify, not just debug, but be able to edit.
So long as you upload both the DLLs and the PDBs, you should be able to debug successfully without the raw projects on the server. It can be augmented if you have open the matching project / solutions locally. There really isn't a requirement to upload solution, project, or raw code files to the server to debug effectively, remotely. It should be noted that breakig while debugging will hang the app domain on the target application, and as such, should be done with caution in a multiuser environment.
You do not need the project files in order to debug files.
You should read about remote debugging.
Update:
What you want to do sounds very dangerous in a production environment. If you want to develop, develop locally.
Regardless - project and solution files are organizational tools in visual studio as well as build files for the MSBuild build tool. If you don't have either visual studio or MSBuild installed on the server, there is little point in having the project and solution files on it.
Why do you need to develop on a production machine?
I'm comparing it Java where you can start your application server in debug mode, then attach your IDE to the server. And you can change your code "on the fly" without restarting the server. As long as your changes don't affect any method signatures or fields you can just hit recompile for a class and the application server (servlet container) will reload the class.
I suppose this is impossible in ASP.NET since all classes are packed into assemblies and you cannot unload/reload assemblies, can you ?
So when you have an .aspx page and an assembly deployed to GAC and your codebehind changes you have to redeploy the assembly and reset IIS. I'm talking about Sharepoint applications in particular and I'm not sure whether you have to do iisreset for private assemblies but I guess you have too.
So the best way to debug aspx pages with code behind I guess would be to get rid of the codebehind for the time of active debugging and move into the page, then when it is more or less working move it back to codebehind. (This would be applicable only for application pages in Sharepoint, site pages don't allow inline code )
How do you approach debugging of your ASP.NET applications to make it less time consuming?
From Matt Smiths blog on how to get F5 debugging with sharepoint. A very cool trick.
Create a web application project in Visual Studio (File -> New -> Project -> ASP.Net Web Application, not File -> New -> Web Site).
Move the .csproj and .csproj.user files, along with the Properties folder, into C:\inetpub\wwwroot\wss\virtualdirectories\, where is the name or number of the web application corresponding to the SharePoint site you'd like to debug on.
Attach the project to an existing solution (e.g. STSDEV project).
Set as startup project (right-click project name, "Set as Startup Project").
Access project properties (right-click project name, "Properties") and click
Under the "Servers" setting, click "Use IIS web server", then enter the URL to the SharePoint web application you want to debug on, e.g. http://mymachine:99.
Yes private assemblies DO NOT require reset of the IIS. So you should just to xcopy new version to the application's Bin directory and refresh the page (e.g. by VS post build event as I did).
But there are some trade offs. You should decrease trust level in application web.config file:
<system.web>
...
<trust level="WSS_Medium" originUrl="" />
...
</system.web>
By the way. I do not suggest to deploy like this. It's just workaround for comfort write-test-debug cycle length.
If you are using the GAC, you can at least do iisapp.vbs /a "App Pool Name" /r instead of iisreset (it's quicker to recycle a single app pool than to restart IIS).
First, develop on a computer running SharePoint. Preferably, this means running Windows Server 2003 on Virtual PC or VMWare. This will let you deploy and debug SharePoint code directly, rather than having to copy files between servers and use the remote debugger.
Use a VS add-in to simplify the process of deployment and debugging. I've been using WSPBuilder but I think there are others out there. WSPBuilder has commands to deploy solutions, package them as WSPs, and attach your debugger to the local IIS process. It won't allow you to add/remove assemblies on the fly, but you can set breakpoints and run code through the Immediate window in VS.
Depending on how your production server is configured, it's usually a good idea to develop on a server with full/trust security settings, including disallowing code blocks in ASPX files. This makes debugging a little more difficult, but it reduces the number of nasty surprises you'll have when your code is finally deployed to production.
And you can change your code "on the fly" without restarting the server
You can accomplish this with ASP.net if you make a Web Site project (as opposed to a Web Application Project). Using a Web Site project, you can post changes to code-behinds without having to refresh anything on the server, and the server does the compile work for you on all code changes. See here for more info on this.
This should also solve your difficulties with deploying the assembly to the GAC. As the server handles all compilations for Web Site projects, you wont have to redeploy any assemblies when changing files.
Use an automated testing framework (NUnit) to write integration tests. This won't work for everything, but of course, it depends on what you're testing.
If you also have TestDriven.NET installed, you can run individual tests with the debugger. This has been helpful.
WSPBuilder Extensions has a "deploy to GAC" shortcut, unfortunately it never works for me. But it's a really quick way to code->compile->test.
If you're not using WSPBuilder Extensions, you can instead open a command prompt and run
gacutil /u yourassemblynamegoeshere
gacutil /i yourdllgoeshere.dll
If you do this often, you can put it in a post-build event or in a batch file. Also, I'm unclear whether the gacutil /u (to remove the DLL first) is necessary.
What it seems like you're trying to do is tell Sharepoint "When I start debugging in Visual Studio, use the version of the DLL that was compiled in the project's /bin/debug directory instead of the version of the DLL that is registered in the GAC." I haven't solved that problem, but here is how I debug Sharepoint.
A developer machine is Win2008, IIS 7, MOSS 2007, VisStudio 2008, and WSP Builder installed. Inside VS2008, a button is added to attach to w3p.exe process, Andrew's HOWTO attach to w3p
The solution file has two projects:
* First project is the .WSP that deploys all the app pages, including the DLL. Use WSPBuilder menu items for handling the .WSP creation and deployment.
* Second project is for the DLL behind the pages.
If you want the DLL to be copied to the GAC regularly, add a post-build event to the DLL's project that copies from /bin/Debug to the GAC. But, these days, I find I have just been recompiling the solution and then deploying the .WSP using the menu items, and then starting up the debugger using the button. It takes me an F-key and 3 clicks and about a minute for most of my projects, but I suppose it could be quicker.
