ASP.NET Error: Could not load file or assembly App_Web_z9w33txs

How did you get rid of these annoying ASP.NET errors: Could not load file or assembly 'App_Web_z9w33txs, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null'

This has only happened to me once before. It seems like it is related to ASP.NET caching some assembly dynamically, but not recompiling it for some reason. Thoughts? How do you fix this? What causes it?

More Info: This is happening to a WCF Service being called via Ajax from my Default.aspx page. The Default.aspx page loads fine.

removed stack trace

Final Update:
So this is happening to me at least 5 times a day now. I have to shutdown the app pool.
Go into C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files and deleted the files here Then restart the app pool. Anybody else run into something like this? Should I just break down and create a support case with Microsoft.

Close your solution, shutdown IIS, go to:

C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files\

And delete all of those files. Then restart IIS and try it all again.

Sometime I have got such error and began to research how to resolve it. Just deleting ASP.NET temporary directory didn't any influence in my case. Then I just have added such attribute to web.config compilation node:

<compilation debug="true" tempDirectory="c:\temp" >

I hope that this can help and other people.

Try closing Visual Studio and then deleting all the folders in your Temporary ASP.NET Files folder by running the following from the Command Prompt:

rd "%TEMP%\Temporary ASP.NET Files\." /s /q

or from PowerShell:

gci "$env:TEMP\Temporary ASP.NET Files" | % {ri $_.FullName -recurse}

Depending on which Frameworks are used, also clear the following folders on the web server:

%windir%\Microsoft.NET\v1.1.4322\Temporary ASP.NET Files\
%windir%\Microsoft.NET\Framework\v2.0.50727\Temporary ASP.NET Files\

If you are getting this error after compiling and/or publishing changes your apps, try the compile option "Use fixed naming and single page assemblies".

Sometimes I get that when I upload a change to a server and the app hasn't recompiled yet. Those may be temp files, try restarting the IIS Admin service (if you can) to see if it goes away.

I have got that error. I Choose "Clean Solution" and then "Rebuild Solution". Once my rebuild succeeds the error goes away. I dont think it is just a WCF thingy.
