在kali linux 2020 上的monoDevelop IDE 中找不到“/usr/lib/mono/msbuild/15.0/bin/Roslyn/Microsoft.CSharp.Core.targets”

Question

I am new to c# programming and specially new to mono compiler and mono related things on linux. when i wrote

using System;

namespace HelloWorld
{
    class MainClass
    {
        public static void Main(string[] args)
        {
            Console.WriteLine("Hello World!");
        }
    }
}

on mono develop IDE and hit the build button i am getting

/usr/lib/mono/msbuild/15.0/bin/Microsoft.CSharp.CurrentVersion.targets(5,5): Error MSB4019: The imported project 
"/usr/lib/mono/msbuild/15.0/bin/Roslyn/Microsoft.CSharp.Core.targets" was not found. 
Confirm that the path in the <Import> declaration is correct, and that the file exists on disk. (MSB4019) (HelloWorld)

this error. i did some research i can't understand any solution because i am completely beginner to mono c# programming on linux

Answer 1

I used to meet " couldn't find Microsoft.CSHARP.Targets". And the solution is to change it as "Microsoft.Csharp.targets". So maybe you can try the same way.
