I have got the same issue. It seems like Visual studio 2005 and the web application pool running ASP.NET 2.0 are having a conflict over the temporary folder.
The workaround I have got for now is:
- If you have visual studio 2005 is open, close it
- Go tot the ASP.NET temporary folder for v2.0 of the framework
<Windows dir>\Microsoft.Net\Framework\v2.0<extra numbers>\Temporary ASpNET pages
- Remove the folder for your application (or all of them)
- Reset IIS (on a command line window, >iisreset) [not always needed, but I had to use it sometimes]
- First Browse your page from IE (http://localhost/your app)
- Then reopen Visual studio And it should work nowI hope it will work for you as he does for me.
从这行看，您的IIS中ASP.NET版本应该是正确的，但是如果操作系统是2003的话，还要把应用程序池ASP.NET2.0.
