I want to bind python function with C#'s delegate method in winform

C# Code

public delegate string CallBackFunc(string content);
using (Py.GIL())
  {
      using (PyScope scope = Py.CreateScope())
      {
          scope.Set("main", this);
          scope.Exec(pycode);
      }
  }

Python Code

def test(input):
   return "OK"
res = main.CallBackFunc(test)

When I test in program ,GET the Error Infomation:Type was not found "System. Reflection. Emit. TypeBuilder" on the constructor,
What should I do For this?

This is not a support forum, it is not an adequate answer to me closing your ticket "System.Reflection.Emit.TypeBuilder" Error #1505 to just open a new one
Does this also happen with the current master branch?

1.Thank you for attention, Because of the lack of relevant information about delegate, I have been beseted with this problem for several days, I just found some solutions ,such as #1471,but it's no helpful for this.
2.I just test the newest release (Ver. 2.5.2), I am not sure whether this also happen with other version.
