Showing Assembly Bindings in ASP.NET (and SharePoint)

The instructions for this should actually show up as a suggestion when you get an Access Denied error when trying to load a custom assembly in ASP.NET (and by extension, SharePoint.) But for quick reference, here it is:

1. Open regedit.exe.
2. Navigate to HKLM\SOFTWARE\Microsoft\Fusion.
3. Add a new DWORD entry named “EnableLog”.
4. Set the value of the entry to 1.
5. Reset IIS (at a command prompt: “iisreset.exe /restart”.)

Recreate the error. The ASP.NET error text should now include assembly binding information.
