如何修复错误 NETSDK1 project.assets.json 文件未找到。 运行 NuGet 包还原以生成此文件

Question

I cannot run my new .netcore mvc application. The dependencies always show warning icon.

And I got this error message when run my new asp.net mvc applicationafter a few hours of searching, I got a few answers. but the answer still cannot be applied to run my application. I have tried using dotnet restore , nuget restore , dotnet build , etc. but still no one solved this problem. when I run dotnet restore this message appears

when I run nuget restore this message appears

Previously I used Microsoft Visual Studio 2017. I uninstalled it and replaced it with Microsoft Visual Studio 2019. Was there something conflict when I installed Microsoft Visual Studio 2019?

I just want to run my application. but I don't know what's wrong with my application?

Hopefully some of you can help me. Thank you in advance
