BLOB field in EF4 generate System.NotSupportedException:
PrimitiveTypeKind.Binary
----------------------------------------------------------------------------------
Key: DNET-456
URL: http://tracker.firebirdsql.org/browse/DNET-456
Project: .NET Data provider
Issue Type: Bug
Components: Entity Framework support
Affects Versions: 2.7.7, 2.7.5, 2.7, 2.6.5, 2.6
Environment: Win7(32) - visual studio 2010 - EF4
Reporter: Full Metal Jacket
Assignee: Jiri Cincura
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.
