Not completely sure what you're looking for, especially as when running in the context of a unit test you'll wind up with:

mscorlib.dll
Microsoft.VisualStudio.TestPlatform.Extensions.VSTestIntegration.dll

(or something similar depending on your test runner) in the set of assemblies that lead to any method being called.

The below code prints the names of each of the assemblies involved in the call.

var trace = new StackTrace();
var assemblies = new List();
var frames = trace.GetFrames();

if(frames == null)
{
    throw new Exception("Couldn't get the stack trace");
}

foreach(var frame in frames)
{
    var method = frame.GetMethod();
    var declaringType = method.DeclaringType;

    if(declaringType == null)
    {
        continue;
    }

    var assembly = declaringType.Assembly;
    var lastAssembly = assemblies.LastOrDefault();

    if(assembly != lastAssembly)
    {
        assemblies.Add(assembly);
    }
}

foreach(var assembly in assemblies)
{
    Debug.WriteLine(assembly.ManifestModule.Name);
}
