Add-Migration has no 'IgnoreChanges' parameter

[steamwings]

When I run Add-Migration InitialCreate –IgnoreChanges in package manager console, I get Add-Migration : A parameter cannot be found that matches parameter name 'IgnoreChanges'.
I just created this project yesterday and I'm running VS2019 which shows no relevant updates available.

@steamwings - That could be product issue. Are you using EF Core or EF6?

[steamwings]

It's an ASP.NET Core project. I can see I have the EF6 tools component installed, but I don't see a separate component to install for EF Core.

[smitpatel]

Can you share a repro project which we can investigate?

Moving this to EF6 repo.

[steamwings]

Here's the whole project:
https://github.com/steamwings/aspnetefcore-dbfirst-migration
There's also a text file called PackageManagerSession.txt in case that's helpful.

[bricelam]

The parameter is there in 6.3.0. I suspect you're inadvertently using the EF Core cmdlet.

https://github.com/aspnet/EntityFramework6/blob/2f61cffeb5e09708a20bc6e3f4414b43407170a3/src/NuGet/EntityFramework/tools/EntityFramework6.psm1#L380

[steamwings]

Yep, I should have been looking at the EF Core reference instead of the EF6 reference. I hope y'all are able to bring migration support to existing databases with EF Core. Thanks!

[bricelam]

Note, to do this on EF Core, comment out the contents of the Up method, run the migration, then uncomment. Issue dotnet/efcore#2167 is about making this experience better.
