Add migration - Both Entity Framework Core and Entity Framework 6 are installed

Question

I have a solution with multiple projects one of them with EF 6 and another one with entityframeworkcore.

The Entity Framework Core tools are running. Use 'EntityFramework\\Add-Migration' for Entity Framework 6.

Answer 1

For EF6:

EntityFramework\Add-Migration <MIGRATIONNAME>

For EF Core:

EntityFrameworkCore\Add-Migration <MIGRATIONNAME>

Answer 2

I had this same scenario happen on our project that spans now ~20 years in history.

Depending on luck, I would sometimes get that PackageManagerConsole<\/code> was using EFCore<\/code> sometimes EF6<\/code> .
