Object reference not set #7

Closed chris-cubhub closed 5 years ago

chris-cubhub commented 5 years ago

I've got a code first model using EntityTypeConfiguration maps that are created through reflection. I've added a DbSet to the AppContext protected DbSet<QueryModelClass> QueryData { get; set; }

I'm getting a "Obect reference not set to an instance of an object" exception when I try to do a join.

Configuration problem on my end.

It would be nice to be able to past a List into this instead of having to convert that into a fake anonymous object.
