In a netstandard20 project, I'm using Npgsql.EntityFrameworkCore.PostgreSQL 3.1.0 and I'm having an issue using Guid as the type for my primary keys. If I use Database.EnsureCreated() to create the schema, the primary key columns get created with data type uuid. With everything the same except changing it to use Database.Migrate() creates all the primary key columns with data type text and then I get exception: Npgsql.PostgresException : 42883: operator does not exist: text = uuid when I try to perform any operations.
There is a single migration in my project to create the initial database. In that migration and also in the "context model snapshot" that are auto-generated, the primary key columns are all defined as Guid.
I need to both use the Database.Migrate() method to create the database and also have it create the Guid primary key columns as uuid. How can I make sure it creates the columns correctly?
I found this issue and response after posting my question. It led me to the correct answer which was that when I created the migration I was using sqlite. I needed to blow away the migration created against that data provider and regenerate it.
