Hi all,
I used the DBMetal.exe to create the c# files for my MySQL database,
but i notice that the tables don't support the FirstOrDefault()
method.
I was wondering if there was any plan to put that in any time soon.
For me, it's kind of a pri-0 feature, since i use it everywhere i need
to get a single item from a database (i've found it to actually be one
of the most useful parts of LINQ).
Plans? Thoughts?

Some methods are already supported this way (when they're given an argument), so we can expand their behavior to FirstOrDefault() handling. Bryan, this could be a good way to enter the project :)

ok, i'm back, i've been busy on a project, but i'm back to where i
need this again. what's the current status? has it been implemented
yet? if not, can you point me in the direction i need to look in order
to get it implemented?

As far as I know, nothing's been done for this.
Anyway, by taking a look at it, it appears that FirstOrDefault method is supported, so I'm interesting in knowing what's going wrong.
There are two points where methods are handled:
1. QueryRunner.SelectScalar() handles top level method calls on expressions (according to your sample, this is the concerned point).
2. ExpressionDispatcher.AnalyzeCall() handles method calls within expressions (intermediate methods).
