Solution 1:^[1]

Thank to Maytham (propose me about Visual Studio 2022 preview) and Jon Skeet (about how to get Visual Studio 2022 preview, it is different with Visual Studio 2019 preview downloading).

Solution: In Visual Studio 2022, choose Preview channel. Then update to VS 2022 preview, then we can choose Target framework .NET 7.0 easily.
