I have a project created from New -> Web Site in Visual Studio 2005.
When I try running the web site, i get the following ArgumentException.
"Culture name 'sources_app_code' is not supported. Parameter name: name"
But the program runs fine.
Anyknow know why this exception occurs?

Are you using localization in your project? It seems the problem is with the setting of locale of the current thread.

Well, I'm getting lots of "A first chance exception of type 'System.ArgumentException' occurred in mscorlib.dll" messages in output window.
(with the error message: Culture name "....." is not supported)
They are thrown because of .svn folder in App_GlobalResources.
If I remove .svn folder, those exceptions are gone.
Is there any workaround for this problem other than removing .svn folder?
Or can these exceptions be ignored safely?

It seems you are using SVN source control and having problems with the hidden svn folders which maintain the state of files locally. I have read that ASP.NET web projects have issues with .svn folders and you might need to rename these folders. Check out
Hope this helps,

I am getting the same error too, and I am running VS 2005 (one of the articles linked to on this post said that "this problem" was fixed in VS2005.) The error happens right when I start my web application. Here is some more information on it:
Message="Culture name 'sources_app_code' is not supported.\r\nParameter name: name"
at System.Globalization.CultureTableRecord..ctor(String cultureName, Boolean useUserOverride)
I am not sure what "SVN Source Control" is, we are using TFS here. Also, I only get the error when loading the first time - ie: if I kill the application and then restart it, the error does not happen. BUT, if I kill the application AND the ASP.NET Development
Server - it will happen when I restart the application.

Did you ever solve this issue? We are having the same issue and would love to know how to solve it.

Deleting the .suo file (Visual Studio Solution User Options file) fixed the issue for me.
This issue came up when I upgraded from .NET 2 to .NET 4 for the project.
