Hi!

I wanted to construct dynamic Linq to Entities queries so I added the LinqToolKit which included this nifty library. The problem is that it doesn't seem to work for me. I have spent two days testing different things and it just won't work.

My Code:

Code:
 Return Await Task.Run(Function()
                                      Dim predicate = PredicateBuilder.True(Of PerformanceTest)()    
                                      predicate.And(Function(e) e.TestTime = "201506161553")
                                      Dim res = db.PerformanceTests _
                                      .AsExpandable() _
                                      .Where(predicate) _
                                      .ToList()
                                      Return res
                                  End Function)
The predicate is ignored and the output SQL returns ALL rows.

When I remove AsExpandable and the predicate in the Where clause and add the expression directly, I get the 1 record as expected.

I am baffled as to why something as trivial as this refuses to work. Is it me who is doing something wrong, or what might be the problem?

I have already tested using Or methods, tested adding Compile() to the predicate but everything is without success.

This could save LOTS of code for us if it would just work.
