我跟着跑了

在那之后，我犯了一个错误

Building project ...
Scaffolding failed.
Add Microsoft.VisualStudio.Web.CodeGeneration.Design package to the project as a NuGet package reference.
To see more information, enable tracing by setting environment variable 'codegen_trace' = 1.
RunTime 00:00:03.47

我尝试使用

dotnet add package Microsoft.VisualStudio.Web.CodeGeneration.Design --version 3.1.0

并得到错误

希望你很好。你的csproj看起来像什么？当您试图使用.NETCore时，您的目标框架可能指向.NETFramework。
