Possible Solution 1

I have seen this before when working with ASP.NET Web Sites. If my memory serves me right, you should make sure that the paths to your references are wired up correctly.

i.e. if you added a custom DLL to your project

C:\My References\Some3rdParty.dll

and you moved the DLL to another folder/location. Or you could simply have a reference to a DLL that cannot be found.

If you resolve these reference problems you could find that your App_Code gets compiled all of a sudden.

Possible Solution 2

Right click and go to the properties of each of the .cs files in your App_Code directory in the Visual Studio Solution Explorer and make sure that the Build Action is set to Compile.

Possible Solution 3

If you have your .cs files in sub-folders within the App_Code directory you should add the following to your web.config file:

<configuration>
    <system.web>
      <compilation>
         <codeSubDirectories>
           <add directoryName="MySubAppCodeFolderName"/>
         </codeSubDirectories>
      </compilation>
   </system.web>
</configuration>

Possible Solution 4

1. In Visual Studio, right-click on your Web Site in the Solution Explorer and click Publish Web Site. Make sure that the Target Location is a folder on your machine.
2. Log-in you your web-server and go to the BIN folder there. In the BIN folder on your web site delete all of the App_Web_.dll and App_Web_.dll.compiled files.
3. From your machine, copy your web site (including the App_Web_*.dll's in the BIN) to your web server where your web site is located. The only file you should probably not copy across is your Web.config file.
