I am trying to walk through this tutorial here.
However after successfully installing EntityFrameworkCore in the package manager console using the command:
then running a dotnet restore successfully in the cmd, the project does not register EntityFrameworkCore. In the .csproj file you can see the line
<PackageReference Include="Microsoft.EntityFrameworkCore.SqlServer" Version="1.1.1" />
Unfortunately whenever I add a using statement with Microsoft.EntityFrameworkCore in a file I get the error mentioned in the title. Any idea why this might be happening?
I solved this problem by:
(1) Right clicking the project in the Solution Explorer
(2) Clicking unload project
(3) Click edit the .csproj and check if there is a Package Reference to EF
(4) Right clicking the project again in the Solution Explorer
(5) Then clicked reload project
Now it recognizes EntityFrameworkCore and there are no more build errors
You missed a required Nuget Package, according to microsoft, you will need to install 3 packages in total, but in my case, it is only required 2 packages as the following:
Hope this can solve your problem.
