Hello, I try to create an app able to retrieve Types from .net Assemblies. First case (this one works fine): My application has "A.dll" referenced at compile time. I add "B.dll" at runtime. I can inspect "B.dll" to get all of its Types. I load it using Assembly.Load nor AppDomain.CurrentDomain.LoadFrom(...). Using the same method, I'm adding "C.dll" assembly wich refer to "B.dll" (some types in C inherits from some B classes). I got an exception (System.IO.FileNotFoundException) saying "Unable to laod file or assmebly 'B, Version=0.1.0.0, Culture=neutral, PublicKeyToken=[***]' or one of its dependencies. File not found." (I translated it from the French version I got). This exception is raised on the Assembly.GetTypes() method. Does some one could help me? Kind Regards Cedric
