I converted the CustomCSharpFiles to .NET 4.
When I navigate (after the instal) to http://localhost/Admin, I get a 404 error. When I go to http://localhost/Admin/Default.aspx, everything works fine.
My machine:
- Windows 7 Enterprise SP 1 64bit
- IIS 7.5
- Pipeline modus integrated
- framework 4
- 32 bits set to True
- fysical path to C:\Projects\www.SampleSite.nl\Application
- Standard document to Default.aspx
