Type Mapping for Query

Since we are passing parameters as JSON, we don't really have type information and we don't want to add more overhead on clients to specify types for query parameters. We decided to create implicit operators on QueryParameter type to support json elements conversion to basic types.

The only problem arises when we use custom types and enum.

Enum

In order to create compare Enum as string, you have to use CastAs.String method as shown below.

const methods = [
    {
        where: ["x => CastAs.String(x.PostType) == @0", "Page"]
    }
];

Please make sure to call base.OnModelCreating(modelBuilder) inside your own OnModelCreating(ModelBuilder modelBuilder).
