Must use PackageReference

[cscuser]

packages\Microsoft.Windows.SDK.Contracts.10.0.17763.1000\build\Microsoft.Windows.SDK.Contracts.targets(4,5): error : Must use PackageReference

when i install Microsoft.Identity.Client library using Nuget Manager I got "Must use PackageReference" error in .Net MVC Project.

The error is coming from the package, not from NuGet (see the path to the targets file, as reported by MSBuild).

Looking at the package on nuget.org: https://www.nuget.org/packages/Microsoft.Windows.SDK.Contracts/
it says this:

Requires default package management format set to PackageReference, and NuGet 4.0 or higher.

You can contact the package owner on nuget.org, on the right side under the "Info" block, there's a link "Contact owners".

There's nothing the NuGet team can do about package authors generating errors in their MSBuild files.

@zivkan This is indeed related to: AzureAD/microsoft-authentication-library-for-dotnet#2247

This is not a NuGet issue, as @zivkan says.
