Answer 1

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.

Answer 2

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.

Answer 3

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.

Answer 4

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.

Answer 5

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\
