I have just updated all my nuget packages for my solution (dotnet core 1.1 project).
I am now getting the following warnings and I don\'t really know what they mean.
If you're getting this error for Razor in a netcoreapp3.1, you just need to change the project SDK from Microsoft.NET.Sdk.Razor to Microsoft.NET.Sdk.
Razor
netcoreapp3.1
Microsoft.NET.Sdk.Razor
Microsoft.NET.Sdk
