Problems about Aras Innovator Method Plugin


I'm trying to use the Aras Innovator Method Plugin to debug a sever method in Visual Studio 2017.

Here is the URL of Aras Innovator Method Plugin:

I build the project successfully, but when i try to debug it the error is 'System.InvalidCastException'.

Where the error appeared is 'Aras.Server.Core.CallContext CCO = ((Aras.Server.Core.IOMConnection)serverConnection).CCO;'.

I don't know why because it is a template code.

Any help would be appreciated. Thank you!
