Entity Framework Mapping SQL Server tinyint to Int16

My Entity Data Model is giving me this error:

Error 2019: Member Mapping specified is not valid. The type 'Edm.Int16[Nullable=True,DefaultValue=]' of ... is not compatible with 'SqlServer.tinyint[Nullable=True,DefaultValue=]' of ...

I've tried deleti开发者_运维技巧ng and recreating the property. I don't know what I've done wrong.

A tinyint should get mapped to a .NET byte; Int16 should be the corresponding type for a smallint in SQL.
