'The EntityFramework package is not installed on project even though it is

I first had this issue after new version of EntityFramework came out. It says I could not Add-Migration because The EntityFramework package is not installed on project . Now before links This Answer. It's not that - see below:

enter image description here

And it is absolutely installed:

  <Project Sdk="Microsoft.NET.Sdk">

  <PropertyGroup>
    <TargetFramework>net6.0</TargetFramework>
    <ImplicitUsings>enable</ImplicitUsings>
    <Nullable>enable</Nullable>
  </PropertyGroup>

  <ItemGroup>
    <PackageReference Include="Microsoft.AspNetCore.Identity.EntityFrameworkCore" Version="6.0.3" />
    <PackageReference Include="Microsoft.EntityFrameworkCore" Version="6.0.3" />
    <PackageReference Include="Microsoft.EntityFrameworkCore.SqlServer" Version="6.0.3" />
    <PackageReference Include="Microsoft.EntityFrameworkCore.Tools" Version="6.0.3">
      <PrivateAssets>all</PrivateAssets>
      <IncludeAssets>runtime; build; native; contentfiles; analyzers; buildtransitive</IncludeAssets>
    </PackageReference>
    <PackageReference Include="Microsoft.Extensions.Caching.SqlServer" Version="6.0.3" />
    <PackageReference Include="System.Linq.Expressions" Version="4.3.0" />
  </ItemGroup>

  <ItemGroup>
    <ProjectReference Include="..\Discounted.Models\Discounted.Models.csproj" />
  </ItemGroup>

</Project>

I originally fixed this issue by updating the packages.

I have tried:

  • Rebuilding/Cleaning as well as
  • Deleting the the obj & bin folders
  • Restoring the the Project & Solution
c++sharpentity-framework-core

There was two versions of Entity Framework Installed. After uninstalling the regular EF I had to restart visual studio to get it working.
