A very general question here, how does DevForce EF handles BLOB? Do you have any sample regarding this? Thanks much!

As I did some simple tests, create a table with one column with Data type - varbinary(MAX). Then update edmx and let Object Mapper do its updates. And then I tried to create entity from some pdf, wmv files, size of my test files are about 8MB and 130MB.
The interesting thing is, for the wmv file, when I tried to commit after my entity is created, there raised  System.OutOfMemoryException. However data in DB is updated and complete, because I can retrieve it and create a new file from it.
 
Thanks to whoever would like to share any insights on this issue.
