    RE: Assembly is not getting registered using plugin registration tools

    Microsoft.CrmSdk.CoreAssemblies version 9.0.2.5 working with .NET Framework 4.5.2. Newer versions CoreAssemblies need .NET Framework 4.6.2! I used version 9.0.2.5 (www.nuget.org/.../9.0.2.5) for creating assembly with Framework 4.5.2.

    Rebuild your plugin project in .Net framework 4.5.2 and register. This worked for me.

    Try Aric Levin's suggestion.

    As weird as it may seem, flip the assembly to 4.5.2 and try.

    Seems to work for some other forum users facing the same issue.

    cheers!

    Getting same error since morning today, while registering assemblies with .Net Framework 4.6.2.

    Till last week we were able to register using .Net Framework 4.6.2 and they were working as expected.

    Changed Framework to 4.5.2 and able to register now, having SDK assemblies 9.0.0.0 from NuGet.

    Hi ,

    Could you please post here the screenshot .Net framework version you are building your solution.

    In addition error says  "Dynamics 365 requires version 4.6.2 of the .NET Framework for plugin assemblies" , so which version of .Net framework you are using .

    Try to upgrade .NET framework version and also try with both 4.5.2 and 4.6.2.

    Hi,

    If you are using 4.6.2, can you switch back to 4.5.2 and see if that is working for you.

    I noticed that some recent updates caused this issue to happen.

    Also, what version of CRM 2016 are you on?

    Hi, hope you're doing good.

    Make sure you're compiling the assembly using the 4.6.2 version of the .NET Framework. The error might be related to that .

    Please mark this answer as verified if helpfull.
