I've found #935 which is a very similar issue but can't get it to work. I'm following the same steps but I still get the same error.\r\n\r\nThe C# side\r\n```C#\r\n    public enum MyEnum: byte\r\n    {\r\n        Success= (byte)'S',\r\n        Error = (byte)'E'\r\n    }\r\n\r\n    public class MyClass\r\n    {\r\n        public Dictionary\u003cEnum, BlockingCollection\u003cISomeInterface\u003e\u003e MyDictionary { get; }\r\n\r\n        public MyClass()\r\n        {\r\n            MyDictionary = new Dictionary\u003cEnum, BlockingCollection\u003cISomeInterface\u003e\u003e(); \r\n        }\r\n    }\r\n```\r\n\r\nOn the python side, I began with this code\r\n```python\r\n    from System.Collections.Concurrent import BlockingCollection\r\n    from MyModule import MyClass, ISomeInterface, MyEnum\r\n\r\n    obj = MyClass()\r\n    collection = BlockingCollection[ISomeInterface]()\r\n    obj.MyDictionary.Add(MyEnum.Success, collection)\r\n```\r\nThis fails with `TypeError: No method matches given arguments for Add`. I've tried what seemed to solve it for #935 but get the same results\r\n\r\n```python\r\n    from System.Collections.Concurrent import BlockingCollection\r\n    from System import Enum\r\n    from MyModule import MyClass, ISomeInterface, MyEnum\r\n\r\n    obj = MyClass()\r\n    collection = BlockingCollection[ISomeInterface]()\r\n    obj.MyDictionary.Add[Enum, BlockingCollection[ISomeInterface]](MyEnum.Success, collection)\r\n```\r\n\r\nThis fails with `TypeError: No match found for given type params`\r\n\r\n-  The output of `print(obj.MyDictionary.Add.__overloads__)` is\r\n\r\n```python\r\n    Void Add(System.Enum, System.Collections.Concurrent.BlockingCollection`1[MyModule.ISomeInterface])\r\n```\r\n\r\n**UPDATE**\r\n\r\nRunning this code alone actually works, `add` shows as a bound method in the debugger:\r\n\r\n```python\r\nadd = obj.MyDictionary.Add.Overloads[Enum, BlockingCollection[ISomeInterface]]\r\n```\r\n\r\nHowever, attempting to call the function always fails. I've attempted passing System.byte and 0, instead of the enum, but none of them work.\r\n```python\r\nadd(MyEnum.Success, collection)\r\nobj.MyDictionary.Add[Enum, BlockingCollection[ISomeInterface]](MyEnum.Success, collection)\r\nobj.MyDictionary.Add.Overloads[Enum, BlockingCollection[ISomeInterface]](MyEnum.Success, collection)\r\n```\r\n\r\n","author":{"url":"https://github.com/integerfn","@type":"Person","name":"integerfn"},"datePublished":"2020-04-03T13:31:25.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":14},"url":"https://github.com/1099/pythonnet/issues/1099"}
