Net Standard 2 is not compatible with Net Core 2 #1909

Closed wgutierrezr closed 6 years ago

wgutierrezr commented 6 years ago

I have multiple projects in one solution, two of them class libraries: Net Core 2 Class Library (EMS.Entities) and Net Standard 2 Razor UI class library (EMS.UIService), using VS 2017 Pro.

EMS.UIService cannot compile because the error (included dotnet restore command) : C:\Projects\EMS2\EMS\EMS.UIService\EMS.UIService.csproj : error NU1201: Project EMS.Entities is not compatible with netstandard2.0 (.NETStandard,Version=v2.0). Project EMS.Entities supports: netcoreapp2.0 (.NETCoreApp,Version=v2.0) [C:\Projects\EMS2\EMS\EMS.sln]

I googled this error and did almost every recommendation to solve it but still the same error.

I will appreciate any suggestion to solve it.

Regards.

Is the UIService Project a netstandard project while the Entities project is netcoreapp? You can't reference a netcoreapp project from a netstandard project. Only the other way around.

You can switch the UIService class library project to be netcoreapp and it should work. Otherwise, you need to make the Entities project netstandard.

I'm going to close this now. Let us know if you have more details or can clarify whether you were trying to have a .NET Standard Library reference a .NET Core library or the other way around.
