After reading through several answers (.NET Core 3.0 - Preview 2 - Razor views don't automatically recompile on change) that recomend installing Microsoft.AspNetCore.Mvc.Razor.RuntimeCompilation NuGet package to get back runtime compilation, I tried the suggested solutions but the project gets the following error message simply by installing the package without even using AddRazorRuntimeCompilation():
The project "project name" must provide a value for configuration
double clicking in the error leads to the following path:
C:\Users....nuget\packages\microsoft.aspnetcore.razor.design\2.2.0\build\netstandard2.0\Microsoft.AspNetCore.Razor.Design.CodeGeneration.targets
But there is no indication as to what is wrong with this file
