VSCode errors :...already contains a definition for...| The call is ambiguous between the following methods or properties,

Question

I am having these errors in VSCode -> GNU/Linux:

• The namespace '' already contains a definition for 'GCoreT' [testc]

For this behavior I have read this,

How to fix "namespace x already contains a definition for x" error? Happened after converting to VS2010

but I can not find the solution, that works for me.

• The call is ambiguous between the following methods or properties: 'GCoreT.mapTex(string, E[])' and 'GCoreT.mapTex(string, E[])' [testc]

• Type 'GCoreT' already defines a member called 'mapTex' with the same parameter types [testc] void GCoreT.mapTex(string text, E[] add)

.

I think this is the most relevant simplified code.

using System;

namespace testc
{
    class Program
    {
        static void Main(string[] args)
        {
           //.. 

        }
    }
}

using System;

class GCoreT{
      ^^^------------------> he says 0


    public Ene[] GTEne (String tex, E[] ene){
    //..    
    mapTex(tex, ene); 
    ^^^------------------> he says 1
    //..
    }

    private void mapTex(String text, E[] add){
                 ^^^------------------------------> he says 2
        //..
    }
}

VSCode says:

0

The namespace '' already contains a definition for 'GCoreT' [testc]

1

The call is ambiguous between the following methods or properties: 'GCoreT.mapTex(string, E[])' and 'GCoreT.mapTex(string, E[])' [testc]

2

Type 'GCoreT' already defines a member called 'mapTex' with the same parameter types [testc] void GCoreT.mapTex(string text, E[] add)

Answer 1

Restarting Omnisharp worked for me. Press CTRL + SHIFT + P, then select 'Restart Omnisharp' from the list

Answer 2

Have you tried restarting VSCode? Could be worth a try. I have faced a similar issue and the problem seemed to magically disappear when I restarted VSCode. Seems like a bug in VSCode that when you rename namespace in certain cases it clings on to the old namespace name.
