I have used NGEN to create native images of several assemblies used by my application. However, those images are not loaded when running the application and I have no idea why.
This is a typical log from fuslogvw:
*** Assembly Binder Log Entry (2/05/2012 @ 13:29:04) ***
The operation failed.
Bind result: hr = 0x80070002. The system cannot find the file specified.
Assembly manager loaded from: C:\Windows\Microsoft.NET\Framework64\v4.0.30319\clr.dll
Running under executable C:\MyDir\MyApp.exe
--- A detailed error log follows.

And the information from ngen.exe about that assembly:
C:\MyDir>ngen display MyAssembly.dll

NGEN Roots:

NGEN Roots that depend on "C:\MyDir\MyAssembly.dll":
C:\MyDir\MyAssembly.dll
Native Images:
MyAssembly, Version=1000.0.0.0, Culture=neutral, PublicKeyToken=null
I used the ngen.exe located in C:\Windows\Microsoft.NET\Framework\v4.0.30319\ and my assembly's target framework is .NET Framework 4. I didn't recompile the assembly after having created the native image.
Any help would be appreciated.
