Please please please write real doc Entity Framework + Postgres Migrations

[yoDon]

Entity Framework is very important.

Migrations are a CRITICAL part of using Entity Framework.

The existing Sql Server sample doesn't work with Postgres, takes a considerable amount of work to hack into a state that can work with a different database, and in the end doesn't explain how to set one's one project up to create migrations.

It's highly not-trivial to figure this out.

There are many closed issues on this topic, none of which actually tell a normal developer who isn't on the Aspire team how to create a migration.

Examples include:

• Postgres/SQL Server EF components make it hard to run dotnet ef to create migrations, etc. aspire#398
• Add database migration playground and skip connection string validation for EF tooling aspire#2263
• Write guidance for using Entity Framework migrations with Aspire solutions #64
• Postgresql setup for local deployment aspire#3425

This is NOT a solved problem. This is NOT a documented problem.

Please, please, please, write a real end-to-end tutorial that shows how to actually create migrations, not just apply migrations that happen to already exist.

Feels like we should have a tutorial on how to use various databases with aspire. This would cover:

1. The database options
2. Databases in containers
3. Volumes for data persistence
4. Entity framework + aspire
