Hi All, I was trying to register the one of the custom workflow activity using the plugin registration tool, I got the below error even though I do not get any compile error in Visual Studio.

I checked the Input parameters of the custom workflow activity where there are two params such as optionset and lookup value. The below is the code to define the Input Parameters.

[Input("Software Product")]
[RequiredArgument]
[ReferenceTarget("agency_software_product")]
public InArgument<EntityReference> SoftwareProduct { get; set; }


[Input("Product Program")]
[RequiredArgument]
[AttributeTarget("agency_software_product_functionality", "agency_product_program")]
public InArgument<OptionSetValue> ProductProgram { get; set; }

Can anyone help me what that error means?

    I think you are using an invalid .Net framework, please refer below and update your .Net framework as par your organization..

    Hi Mohsin Ali

    The error message should clear say that it is a .net Framework Issue.Exception was not handled here properly. 

    Once other concern, if it is a .net framework issue, how come I did not get any single error when I compile my code with version 4.7.2 where I uses the CRM SDK dll's which supports only 4.5.2

    Anyway, I will downgrade the version in  properties and re-compile the code and try to deploy and update you

    Hi Mohsin, After I compiled the code with 4.62 .Net Frame Work, it worked. Thanks for your help
