Inital migration needed for migration tool

[psijkof]

Opening the migrations tool without having a single migration yet results in error message.

Steps to reproduce

Include a complete description that I can redo to reproduce the issue.

Further technical details

It would be awesome to have the tool create a db context from a given model (namespace). I feel that is missing. Reverse engineering works very good. Just could use some help in code first scenario

I am not able to reproduce, could you share a project that causes this issue to oocur?

Could you clarify this with an example, I do not understand this

But basically what i did was, reverse engineer an existing database. build solution, use migration tool

As to code first: Maybe I'm missing something, but after I defined my model classes, I have to manually create a db context. It would be awesome to 'reverse engineer' the model classes and generate a dbcontext.

Never heard about that idea before - it is not so simple.. Suggest you file a seperate issue for that feature request.

OK, this issue is just a bug (your test project is a .NET Core project, and I have not done enough testing with that project type)

Fixed in latest daily build, thanks for reporting this!
