Very strange error, converted Parallel / Async Test 4.0 project ref to 4.5

Question

Very strange error, converted Parallel / Async Test 4.0 project ref to 4.5 and worked, but now suddenly getting errors below, seems to be async keyword or am I still refrencing the wrong Libs?

Could not load type 'VB$IStateMachine' from assembly 'Tridex Async Test, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'.

Answer 1

Hi. This doesn’t look like a TPL Dataflow-related issue since Dataflow did not exist in .NET 4. Can you provide some context what your app was doing in .NET 4 and how you ported it to .NET 4.5? So we can redirect your question to the right forum. Thanks.

hi ,

No I still hjave the same problem as described,

I have had to remove the ASYNC KEYWORD from all function being tested, Its really strange , all other threading functionality works from the converted 4.0 projects to 4.5, but the ASYNC KEYWORD just keeps giving me this!! is it a version conflict as I have visual studio 4.0 and 4.5 installed on the same system, usually never had issues, but hey?

You can try this code (after translating it to VB) somewhere in your program to dump the assemblies that are currently loaded. See if there is a version or a path that doesn't match the rest.

 

using System;

using System.Reflection;

 

namespace Test

{

    class Program

    {

        static void Main(string[] args)

        {

            foreach (var asm in AppDomain.CurrentDomain.GetAssemblies())

            {

                Console.WriteLine("FullName={0}\nCodeBase={1}\n", asm.FullName, asm.CodeBase);

            }

        }

    }

}

Answer 5

Thanks for your reply, I will give your sample a try from above, but I have use Process Explorer to reference the assemblies, and as you know its quite detail on reporting, and states that the .exe is using System. Threading references the 4.5 Lib / Directories.

I don't know if Visual studio is getting confused with the side by side installation with version 4.0 and the ASYNC CTP, but will try a virtual machine install with win7 / win 8 developer preview, and up dater you on what I find...

 Thanks Guys,

And keep up the good work...
