Did you manually verify that this works? You can install a local build of dotnet-ef using the following command:

build -pack
dotnet tool install -g dotnet-ef --version 5.0.0-* --add-source C:\path\to\efcore\artifacts\packages\Debug\Shipping

Things to test: (manually is fine)

• Does it work with short and long options unknown to ef? (e.g. -u and --unknown)
  • If not, do they work with --? (e.g. dotnet ef dbcontext info -- --unknown)
• Are arguments passed into Program.BuildWebHost/CreateWebHostBuilder/CreateHostBuilder?
• Are the arguments passed into IDesignTimeDbContextFactory.Create?

Just note to myself: to install the tool for test you need to run:

build -pack
dotnet tool install -g dotnet-ef --version 5.0.0-dev --add-source C:\path\to\efcore\artifacts\packages\Debug\Shipping

5.0.0-* picks up a different version.

@bricelam I've determined that though the above is installing the dotnet-ef and ef tools, it appears to be picking up it's copy of Microsoft.EntityFrameworkCore.Design.5.0.0-dev.nupkg from somewhere else i.e. the tool reflects the changes I've made to the dotnet-ef and ef projects - but not to the EFCore.Design project - even though the Microsoft.EntityFrameworkCore.Design.5.0.0-dev.nupkg is updated and is available in the path I pass to --add-source. Any ideas on how to fix this so I can test?

[lajones]

@bricelam Never mind. I cleared my NuGet caches and a warning message showed up saying it was picking up an old version. If I then added the path from --add-source as one of the Package Sources for the target app, then it picked up the correct version of Microsoft.EntityFrameworkCore.Design.5.0.0-dev.nupkg during build.

@bricelam I've now manually verified that this works. If you pass the -v flag to any command you'll now see a Remaining arguments output which lists the arguments being passed into each command. DatabaseOperations, DbContextOperations and MigrationsOperations now all have access to a _args variable which is filled in with any remaining arguments.

@bricelam Also added the Powershell updates after testing those too.

Just a few minor comments

This should coalesce to empty array.
