Can't use .NET Core 5.0 application with Visual Studio Community 2019 Version 16.7.5

Question

A week ago I wanted to use .NET Core 5.0. I have installed it on my PC:

I used do.net commands to create some applications. It worked well. I can even launch every application I have created with .NET Core 5.0. Problems start when I create .NET Core Application with Visual Studio.

The solution explorer is full of warning signs:

ConsoleApp1.csproj file shows me that I use .NET Core 5.0 version as it should be:

<Project Sdk="Microsoft.NET.Sdk">

  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>net5.0</TargetFramework>
  </PropertyGroup>

</Project>

I didn't change the applications yet. Program.cs:

using System;

namespace ConsoleApp1
{
    class Program
    {
        static void Main(string[] args)
        {
            Console.WriteLine("Hello World!");
        }
    }
}

I decided that I should choose the Target Framework for my application. I went to the project settings and saw that my taget framework wasn't selected. I wanted to choose one but there is only .NET Framework target frameworks:

I tried to watch answers on the ente.net. That is why I checked Use previews of the .NET Core SDK (requires restart) on:

It still doesn't work. It doesn't work with old or new projects. Maybe there is no chance to Debug .NET Core 5.0 with Visual Studio now?

To use .NET Core 5.0 you should download the preview version of the visual studio separately (from here: https://visualstudio.microsoft.com/vs/preview/ ). If you have already installed .NET Core 5.0 SDK and don't know how to switch back version of the .NET Core in your project to an earlier one, then write.netcoreapp3.1 (maybe another version) instead of.net5.0 in your .csproj file. For example my ConsoleApp1.csproj :

<Project Sdk="Microsoft.NET.Sdk">

  <PropertyGroup>
    <OutputType>Exe</OutputType>
    <TargetFramework>netcoreapp3.1</TargetFramework>
  </PropertyGroup>

</Project>
