c# - A procedure imported by {myassembly} could not be loaded

Question

when running a prorgam, it seems that I am missing a library, when I launch the output of my project I get an exception at startup.

A first chance exception of type 'System.IO.FileLoadException' occurred in mscorlib.dll
An unhandled exception of type 'System.IO.FileLoadException' occurred in mscorlib.dll

Additional information: A procedure imported by 'my assembly, Version=xx.1.1.0, Culture=neutral, PublicKeyToken=7292581204d9e04a' could not be loaded.

'ScriptX.vshost.exe' (Managed): Loaded 'C:WINDOWSassemblyGAC_MSILSystem.Configuration2.0.0.0__b03f5f7f11d50a3aSystem.Configuration.dll', No symbols loaded.

My question is: how can I determine which library is missing because, at this point, I cannot see the values passed to:

mscorlib.dll!System.AppDomain.ExecuteAssembly(string assemblyFile, System.Security.Policy.Evidence assemblySecurity, string[] args) + 0x3a bytes

There is in fact a built in mechanism for just these diagnostics.

(1) In your project properties/Debug, make sure 'Enable native code debugging' is checked:

(2) Raise the show-loader-snaps flag - it is a registry key in the IFEO, and is accessible via the 'GlobalFlags' GUI:

(3) Run the app from a debugger - or attach before the load error. Inspect the (very) verbose output pane. You can mostly skip to the end or look for 'ERROR'.
