1. Open CMD and go to C: \ WINDOWS \ Microsoft. NET \ framework \ v2.0.50727.
2. Enter aspnet_regiis.exe-I
Aspnet_regiis-ga <windowsuseraccount>
3. Disable vs2005 first.
4. Open c: \ windows \ Microsoft. NET \ work \ v2.0.50727 \ temporary ASP. NET files, find the directory of the program you just debugged, and delete it.
5. Disable the IIS server and restart it once.
6. Use IE to browse your program and solve the problem.
