Answer 2

Just want to chip in that i had the same issue but with EntityFrameworkCore 3.0 preview. I solved it by simply downgrading all entityframework 3.0(preview) nuget packages to latest stable (2.2).

Hopefully this helps someone aswell, took me hours...

Answer 3

The issue is because you're having local directory path to one of your {projectName}.csproj file Kindly review your .csproj files by Right clicking project and select Edit {projectName}.scproj

e.g

<Reference Include="Microsoft.EntityFrameworkCore">
      <HintPath>..\..\..\..\..\..\..\Program Files\dotnet\sdk\NuGetFallbackFolder\Microsoft.EntityFrameworkCore\2.1.1\lib\netstandard2.0\Microsoft.EntityFrameworkCore.dll</HintPath>
    </Reference>

If yes than go to Nuget Package Manager and add your library bu selecting nuget.org as Package Source

after restoring from nuget Package manager csproject file will have following tag Added to

<PackageReference Include="Microsoft.Extensions.Identity.Stores" Version="2.1.1" />

Here {projectName} is the name of C# project.
