Unable to retrieve project metadata. Ensure it's an MSBuild-based .NET Core project

Question

I've been researching a lot online but did not find a proper solution. I was trying to use Entity Framework Core with MySQL by using database-first scaffold method to mapping table model while always received this error when applied the command

Unable to retrieve project metadata. Ensure it's an MSBuild-based .NET Core project. If you're using custom BaseIntermediateOutputPath or MSBuildProjectExtensionsPath values, Use the --msbuildprojectextensionspath option.

This is the command I am using to scaffold the database model:

Scaffold-DbContext "server=localhost;port=3306;user=root;password=1234;database=world" "Pomelo.EntityFrameworkCore.MySql" -OutputDir .\Models -f

And this is my .Net Core project setting:

  <ItemGroup>
    <PackageReference Include="Microsoft.EntityFrameworkCore.Tools" Version="2.0.1" />
    <PackageReference Include="Pomelo.EntityFrameworkCore.MySql" Version="2.0.1" />
  </ItemGroup>

  <ItemGroup>
    <DotNetCliToolReference Include="Microsoft.EntityFrameworkCore.Tools.DotNet" Version="2.0.1" />
  </ItemGroup>

Answer 1

For my case this error was solved by downloading latest dotnet-sdk-2.2.107-win-x64

for VS2017 and then dropping and updating database through cmd:

dotnet ef database drop --force --context <<dbcontext>> -s <<startup project directory>> -p <<project directory>>


dotnet ef database update --context <<dbcontext>> -s <<startup project directory>> -p <<project directory>>

Answer 2

I have tried different solutions to solve this error. Did following change in .csproj file.

Solved this issue for .Net Core by edit .csproj file and removed Import tag and then run ef command again in command line.

Add this parameter to the end of your scaffold command "--msbuildprojectextensionspath".
