Register/Use .Net class library having async methods (.net framework 4.5) in AX x++

Posted on by Community Member

Hi All,

I've created a .Net class library which uses some external API which required .Net framework 4.5 and async/await support. When I am trying to register this dll in AX then I am getting error "The selected file is not a valid .NET assembly, therefore the reference cannot be added."

Any idea how can I use this dll in AX.

Thanks in advance

Arun.

    AX 2009 uses .NET Framework 3.5, as far as I remember.

    Is there any workaround or any way to use c# library built in framework 4.0 in AX 2009?

    Yes, you can create a separate .NET 4 process using the library and let it communicate with AX.

    How can we do that? Do you have any samples for that?

    There are a many ways how to develop a program and how to implement interprocess communication. Forget about code samples in the moment; you have to analyze and design the solution before you can start thinking about code.

    For example, you may want to build a Windows service, or a normal application started by a user, or by AX, or you can integrate the library to some existing system. You can communicate via web services, Business Connector, a queue, files or something else...
