我该怎么做：Visual Studio 没有显示错误描述

Question

first of all i dont know what the title error wants from me therefore its this strange title for the problem xD

If I purposely mistype "Count" into "cont", I have an Error or Suggestion from VS that doesn't show any description.

But if i press the 'play' button i can see the error Description in the error window.

I have reinstalled VS and checked all Variables in Unity. I have no idea whats the problem and i dont know what to search for. Cause the intellisense system works and it shows that there is an error at the line but not the error description:/

(What did you try and what were you expecting?) i dont know what to write here?! i say everything in the other input box

From your description, after re-install VS the issue still exists, so the issue should come from the project level cache/settings instead of VS environment file lacking.

You can try to create a new project and writing your code as the simplest like this:

using System;
using System.Collections.Generic;

namespace ConsoleApp1
{
    internal class Program
    {
        static void Main(string[] args)
        {
            List<Upgrade> upgrades = new List<Upgrade>();
            var xxx = upgrades.cont;
        }
    }
    class Upgrade
    {
    }
}

If the issue disappears in the new project, I suggest you delete '.vs' directory, '.vs' directory stores settings and caches, it will be created when you open the solution at the first time. This directory is under the same folder level of.sln file. After deleting it, when you open the solution next time, this directory will be re-generated. Intellisense caches are in this directory, that's why we suggest you to re-generate it.

If the issue doesn't disappear in the new project, please check your VS version, if it is not the lastest, please update it to the latest version.
