azure devops - Pipeline Nuget restore failing on .Net Core 3.0 Preview 8 project (NU1202)

Question

I updated a project from netcoreapp2.2 to netcoreapp3.0 and use Preview8 SDK as well as Microsoft.EntityFrameworkCore.SqlServer, tools, and design.

I can build and run my projects locally just find (VS 2019). But when I try to deploy with Azure DevOps, the Nuget restore gives this error:

NU1202: Package Microsoft.EntityFrameworkCore.SqlServer 3.0.0-preview8.19405.11 is not compatible with netcoreapp3.0 (.NETCoreApp,Version=v3.0). Package Microsoft.EntityFrameworkCore.SqlServer 3.0.0-preview8.19405.11 supports: netstandard2.1 (.NETStandard,Version=v2.1)

Every reference to an EntityFrameworkCore package will result in that error.

I'm setting the .Net Core SDK in the pipeline to Preview8 via a global.json.

I have a NuGet tool installer task, bringing in the latest version, and a Nuget Restore task command running against my solution.

Answer 1

My problem was that I was using the Nuget Restore. Changing it to dotnet restore made the trick.
