Why does the asp.net website administration tool give timeout message (mysql db)?

i have an asp.net-mvc website and I am trying to use the asp.net website administration tool but when i click in visual studio 2010 to launch it, it brings up a browser that says:

An error was encountered. Please return to the previous page and try again.

i can't click back but when i click on "How do i use this tool", i get this error:

Tool Has Timed Out

As a security measure, the Web Site Administration Tool times out after a period of inactivity. Changes to machine.config or web.config may also result in the tool needing to be restarted. To continue configuring your web site, restart the tool.

when i run my website, i am able to connect to the database fine and i am also able to insert new users through the default Account/LogOn interface.

Any suggestions on how to debug why i can't launch the admin tool ?

Solution ：I was getting the exact same error message with VS2010 .NET 4.0 framework. I created my solution in a subfolder titled "C#". Renaming the subfolder to CSharp fixed my problem.
