I have the same issue

No progress since April. Jetbrains please 'unblock' -> it used to be possible to type in the migration name manually so a part of the issue is the decision to hardcode the list to take dropdown entries only.

I suspect the issue may arise when the migration project is separate from the project containing the DbContext.

Hi folks! This issue requires detailed repro steps as I can't reproduce it using a regular EF Core project setup (neither in a single project setup nor with a separate startup + migrations one)

@jektvik your case sounds interesting, I assume, that it may be a key for the problem resolution. Could you please describe your project's anatomy in a little more detail?

Do you have references configured between projects like the following?

graph TD;
    A[Startup project]-->B;
    B[Migrations project]-->C[DbContext project];

[jektvik]

I have 2 projects:

1. project with migrations - cmd line project, startup capable incl connection string
2. project with db context (and main app/models code), in my case an azure functions project

project dependency is: migrations csproj references dbcontext csproj

[seclerp]

And which one you usually select as Startup project and which one as Migrations project in the Update Database dialog?

[jektvik]

It doesn't matter which i select in the dialog as far as the dropdown is concerned (i.e. no matter what i select, the migration dropdown is only allowing 0). But for the command i go with the migration project as both startup and migrations.

@seclerp My case is the same as @jektvik 's. As you can see in the screenshot, my startup and migration project are both set to the project containing migration. Plus startup project only contains 1 option which is the project containing migration, there's no other options I can select.
