Adding C# Web Form to VB Web Application
Is there any way to add a C# Web Form to an ASP.NET 4.0 Web Application that is written in VB.NET? I had an ASP.NET 2.0 *WEB SITE* that I recently converted to an ASP.NET 4.0 *WEB APPLICATION*. It was mostly written in VB.NET with a couple pages that had C# code behinds.
I've read the following article (the end section about mulitple languages):
http://msdn.microsoft.com/en-us/library/t990ks23.aspx
But it does not seem to help for the following two reasons
1) When I converted my site to an application, it didn't seem to add an APP_CODE folder at all
2) I'm not looking to just write a simple class, I actually want to be able to add a WEB FORM with a C# code behind
When I try to add a new item and I select which type of item I want to add, I am only given to option to add a VISUAL BASIC web form.
I have a workaround right now. If I need a new web form with a C# code behind, I take one of my old C# web forms and just copy and paste the form and C# code behind into the project and then rename it and change the class name as well. Then i make my changes and do what I need to do. It seems to work, but I was just wondering if there was an easier way.
You might wonder why want to put C# forms in my VB app. I wrote my app in VB (not well versed in C# but I can read it). I have a programmer working for me that is much more efficient with C#. I don't really have the budget to spend weeks/months getting her up to speed with VB

There are no App_code folders for an asp.net web application. That's for web sites
Note: For Asp.net web app right click on your web app, click add, then new folder then name the new folder App_Code (see attached picture)
You have to add this yourself. VS2010 will not do it for you when you created the web app. Once created add any web form or C# classes files.
Note: If you cannot create it your project may not be setup properly, just in case: what kind of web app project is it?
Asp.net web app, Asp.net mvc2 web app.

How will this help me create new web forms with a C# codebehind file?
mas_oz2003, you should not create an App_Code folder in a web application project. This is because ASP.NET will ALWAYS compile all code in APP_CODE at runtime. It would get compiled twice, once into the web application's main assembly and then again into a seperate assembly. See http://vishaljoshi.blogspot.com/2009/07/appcode-folder-doesnt-work-with-web.html
You can convert the C# code to VB.NET with this tools:

And then you can add the VB.NET files to your web application.

one more thing u may need to add in your web config
<configuration>
<system.web>
<compilation>
<codeSubDirectories>
<add directoryName="VBCode"/>
<add directoryName="CSCode"/>
</codeSubDirectories>
</compilation>
</system.web>
</configuration>
Refer to
http://www.experts-exchang
codeSubDirectories Element for compilation
<configuration>
<system.web>
<compilation>
<codeSubDirectories>
<add directoryName="VBCode"/>
<add directoryName="CSCode"/>
</codeSubDirectories>
</compilation>
</system.web>
</configuration>

anurag_onnet - that would make sense for a Web Project but the asker is building a Web Application. There should not create an App_Code folder in a web application project (see my comment above)

then you can put the C# files there.
