[Mono-dev] Entity Framework - new issues

[Oleg]

Oh, we came to the point I started from on StackOverflov
(http://stackoverflow.com/questions/14582318/nullreferenceexception-with-ef6-on-mono-3-0-3)
with NullReferenceException when I have tried use .Net System.Xml. It is a
good sign :)

I will attach updated sample project with patched EntityFramework.dll and
(expiring within a week) trial license for provider to existing Bug 10245
because if I will attach it here, it will not pass 80Kb limitation. Anyway
issue with post compilation validation looks related to Sys.Xml and this way
it is another bug having workaround for EntityFramework now,
