Tools: Support Xamarin/MAUI Projects (currently requires separate .NET Standard class library)

[rowanmiller]

Tooling is explicitly blocked at the moment, so we'd need to do some work there to enable migrations.

PM> Add-Migration Test
Startup project 'Phoneword' targets framework 'MonoAndroid'. The Entity Framework Core Package Manager Console Tools don't support this framework.

Just an FYI: I've been able to get tooling to work by downgrading the version in NuGet to 1.1.0-msbuild3-final, and then immediately updating it back to 1.1.0-preview4-final. Then rerun Add-Migration and gens the migration within a Xamarin Forms netstandard project.

Anyone knows any alternative solution to this problem?

@raky291 You should be able to create a .NET Standard Class Library to put your EF Core code in and use the tools.

Hi @bricelam thank you

To use the EntityFrameworkCore.Tools with the .NET Standard, I needed to add a console app that references my library, and set it as the startup project.

Correct. You can also just use the class library if you edit the *.csproj to cross-target .NET Core:

<TargetFrameworks>netcoreapp2.0;netstandard2.0</TargetFrameworks>
