Compiler Error CS0759

No defining declaration found for implementing declaration of partial method 'method'.

A partial method must have a defining declaration that defines the signature (name, return type and parameters) of the method. The implementation or method body is optional.

To correct this error

  1. Provide a defining declaration for the partial method in the other part of a partial class or struct.


The following example generates CS0759:

// cs0759.cs  
using System;  
    public partial class C  
        partial void Part() // CS0759  
        public static int Main()  
            return 1;
