ASP.NET Can't Load Assembly

Question

My computer crashed and I'm now unable to start my previously working ASP.NET Web Application in Visual Studio 2008 -- getting the following error:

=== Pre-bind state information ===
LOG: User = Adam-PC\Adam

Answer 1

The answer is I had to delete this folder's contents:

C:/Users/Adam/AppData/Local/Temp/Temporary ASP.NET Files/root/

Answer 2

After a BSOD, I had same error code but with AutoMapper.dll in VS 2010 for a .Net 4.0 MVC 3 project. The resolution for me was to delete the contents of:

C:\Windows\Microsoft.NET\Framework\v4.0.30319\Temporary ASP.NET Files\temp

(This is on Windows 7 x64)

It seems the error message 'Bind result: hr = 0x80070057. The parameter is incorrect.' can be caused when a temporary copy of a referenced DLL becomes corrupted by a system failure. The resolution is to remove this temporary copy. Then when you re-compile the compiler will re-copy the original DLL to the temporary folder.
