Mapping a field of type BLOB sub_type 0 as a Byte[] in EF4, during the call of SaveChanges() method, it returns an incomprehensible exception:
System.NotSupportedException: PrimitiveTypeKind.Binary
I created a dataannotation like:
[Column(TypeName="BLOB")]
public Byte[] filecontent { get; set; }
I can't find online documentation about how to map a blob field in EF4, maybe you can help us.
I know this is a pretty old ticket, but I'll give it a shot. Are you still facing the issue? The `Binary` type is supported in `GetSqlPrimitiveType` now, so I believe this is fixed (already for a long time :)).
