c# - Get package directory task failed unexpectedly

Question

I was working with some examples about "Constructors" and I made this example on Visual Studio:

using System;
using System.Reflection.Metadata.Ecma335;

namespace Classes
{
    class Program
    {
        static void Main(string[] args)
        {
            var customer = new Customer(1, "John");
            Console.WriteLine(customer.Id);
            Console.WriteLine(customer.Name);
        }
    }
    public class Customer
    {
        public int Id;
        public string Name;

        public Customer()
        {

        }

        public Customer(int id)
        {
            this.Id = id;
        }

        public Customer(int id, string name)
        {
            this.Id = id;
            this.Name = name;
        }
    }
}

But when I try to run the code, I get this message:

The "GetPackageDirectory" task failed unexpectedly.

So what is going wrong here? Why am I facing this issue?

I would really appreciate any idea or suggestion from you guys.

Thanks in advance.

Answer 1

u can try dotnet restore and dotnet clean in order. here's a link

edit--- also u can add those codes in ur package library

<PropertyGroup>
    <RestoreFallbackFolders>clear</RestoreFallbackFolders>
  </PropertyGroup>

it will clean up any old package or referances packages. dont worry,it will create them again after u build it ur project.
