Migrating an ASP. NET Core 2.1 project to 2.2

The way to migrate an ASP. NET core project from 2.1.x to 2.2.0-preview1 is simple, open the project's. csproj file and change the value of the <TargetFramework> element to netcoreapp2.2. If your project is the. NET Framework 4.x, you do not need to do this (because it requires a more complex migration approach).
