Well, I'd think how an empty database is created (with noDocument argument being true/false) should not have effect on ReadDwgFile() method being called and the Database being saved as logically. But I could be wrong.

Anyway, I tested with

using (Database db = new Database(false, true))

The result were the same:

Acad2009 32bit: OK;

Acad2011 32bit: getting eFileSharingViolation exception

Acad2012 64bit: getting eFileSharingViolation exception

Since it is very unlikely this would have anything to do with 32/64bit, I'd think this is bug/break in Acad 19.xx (2010/11/12)

Except for OpenFileMode.OpenForreadAndWriteNoShare in ReadDwgFile() method, the other value of FileOpenMode (OpenForReadAndAllShare, OpenForreadAndReadShare and OpenTryForReadShare) seems OK.

So, if I'd avoid to use OpenFileMode.OpenForReadAndWriteNoShare, if I have to read dwg file into database in in the same time do not want the dwg file accessed by others.

A small remark. 19.xx - is AutoCAD 2013 ..., but 18.xx is 2010,2011,2012
