BUG: GetTypeFromCLSID and GetType return incorrect type (327420)

MORE INFORMATION

Steps to Reproduce the Behavior

1. Use the following code to create a file named MyAssembly.cs for version 1, and save it in a directory named v1:

   // MyAssembly.cs code for assembly version 1 
   using	System;
   using 	System.Reflection;
   using 	System.Runtime.InteropServices;
   
   [assembly: AssemblyVersion("1.0.0.0")]
   [assembly: AssemblyKeyFile("vtest.snk")]
   
   
   [Guid("BAF27F93-D60D-4092-815E-F5382C9FBBB4")]
   public class MyClass
   {
   	public string HelloWorld() { return "Hello, World: From V1"; }
   }
   					

2. Use the following code to create a file named MyAssembly.cs for version 2, and save it in a directory named v2:

   // MyAssembly.cs code for assembly version 2
   using	System;
   using 	System.Reflection;
   using 	System.Runtime.InteropServices;
   
   [assembly: AssemblyVersion("2.0.0.0")]
   [assembly: AssemblyKeyFile("vtest.snk")]
   
   
   [Guid("BAF27F93-D60D-4092-815E-F5382C9FBBB4")]
   public class MyClass
   {
   	public string HelloWorld() { return "Hello, World: From V2"; }
   }
   					

3. Create Vtest.snk with the Sn.exe tool:

   // Test client
   using System;
   
   class Test
   {
   	static void Main(string[] args)
   	{
   		Console.WriteLine("Main");
   		Type t1 = Type.GetType("MyClass, MyAssembly, Version=1.0.0.0, Culture=neutral, PublicKeyToken=fadf9433ffb9570a");
   		Console.WriteLine("GetType()          : " + t1.AssemblyQualifiedName);
   		
   		Type t2 = Type.GetTypeFromCLSID(new Guid("BAF27F93-D60D-4092-815E-F5382C9FBBB4"));
   		Console.WriteLine("GetTypeFromCLSID() : " + t2.AssemblyQualifiedName);
   
   	}	
   }
   					

4. Save a copy of Vtest.snk in both the v1 and v2 directories:

   sn.exe -k vtest.snk
   					

5. In their respective directories, compile both MyAssembly.cs files into DLLs.
6. Use gacutil -i to add both versions of MyAssembly.dll to the GAC.
7. Run Regasm.exe on version 2 of MyAssembly.dll.
8. Save Test.cs in any directory you want.
9. Run the following at a command line to find the PublicKeyToken for MyAssembly.dll:

   gacutil.exe -l MyAssembly
   					

10. Edit the following line in Test.cs to include the correct PublicKeyToken:

    Type t1 = Type.GetType("MyClass, MyAssembly, Version=1.0.0.0, Culture=neutral, PublicKeyToken=<insert your PublicKeyToken>");
    					

11. Save the changes.
12. Compile Test.cs into an .exe file.
13. Run Test.exe. The output that is generated will look similar to the following:

    GetType()          : MyClass, MyAssembly, Version=1.0.0.0, Culture=neutral, PublicKeyToken=fadf9433ffb9570a
    GetTypeFromCLSID() : MyClass, MyAssembly, Version=1.0.0.0, Culture=neutral, PublicKeyToken=fadf9433ffb9570a
    					

    Notice that both lines specify version 1.0.0.0.
