Microsoft.VisualStudio.Web.CodeGeneration.Design not being found by the dotnet aspnet-codegenerator tool
问题 I just created an MVC app with dotnet new mvc --name test-project ( netcoreapp3.1 ), without any kind of database access and Identity, which I would like to add by hand for customisation purposes. Then I added some packages in order to use the dotnet aspnet-codegenerator tool. My .csproj looks like this: <Project Sdk="Microsoft.NET.Sdk.Web"> <PropertyGroup> <TargetFramework>netcoreapp3.1</TargetFramework> <RootNamespace>test_project</RootNamespace> </PropertyGroup> <ItemGroup>
