C# Error CS0763 – Both partial method declarations must be static or neither may be static

C# Error

CS0763 – Both partial method declarations must be static or neither may be static

Reason for the Error & Solution

Both partial method declarations must be static or neither may be static.

A partial method declaration cannot have one part static and the other part not static.

To correct this error

1. Make both parts either static or non-static.

Example

The following code generates CS0763:

// cs0763.cs  
using System;  
  
    public partial class C  
    {  
        static partial void Part();  
        partial void Part() // CS0763  
        {  
        }  
  
        public static int Main()  
        {  
            return 1;  
        }  
  
    }
