EF CORE "dotnet ef dbcontext scaffold" Define Data Types

Question

I've been searching the web for a while, but can't find what I'm looking for.

Basically when I run the aforementioned code against my Sqlite DB, it generates all the classes etc, but instead of rendering booleans etc, it chooses to create them as byte[] and all floating point numbers come through as doubles.

I don't want this, as doubles tend to do poorly when doing math against them, and can create incorrect values.

So basically what I want to know, is, is there a way to define the mapping of types. So all "REAL" in the database are created as Decimal and BIT as bool?
