Question

Weird behavior when mixing loading of assemblies using Assembly.LoadFrom and Assembly.Load

I have encountered a weird behavior when loading assemblies with Assembly.

@Kent Boogart: That appears to be the correct explanation. For a full explanation, Suzanne Cook has this blog post which elaborates a little more than the original one you posted: http://blogs.msdn.com/suzcook/archive/2003/05/29/57143.aspx

Following is code leveraging AppDomain.AssemblyResolve -

 // register to listen to all assembly resolving attempts:
 AppDomain currentDomain = AppDomain.CurrentDomain;
 currentDomain.AssemblyResolve += new ResolveEventHandler(MyResolveEventHandler);


 // Check whether the desired assembly is already loaded
 private static Assembly MyResolveEventHandler(object sender, ResolveEventArgs args) {
    Assembly[] assemblies = AppDomain.CurrentDomain.GetAssemblies();
    foreach (Assembly assembly in assemblies) {
       AssemblyName assemblyName = assembly.GetName();
       string desiredAssmebly = args.Name;
       if (assemblyName.FullName == desiredAssmebly) {
           return assembly;
       }
    }

    // Failed to find the desired assembly
    return null;
 }
