Generated SQL with PredicateBuilder, LINQPad and operator ANY

I previously asked a question about chaining conditions in Linq To Entities. Now I use LinqKit and everything works fine. I want to see the generated SQL and after reading this answer, I use L开发者_如何学编程inqPad.

This is my statement:

var predProduct = PredicateBuilder.True<Product>();
var predColorLanguage = PredicateBuilder.True<ColorLanguage>();

predProduct = predProduct.And(p => p.IsComplete);

predColorLanguage = predColorLanguage.And(c => c.IdColorEntity.Products.AsQueryable().Any(expr));

ColorLanguages.Where(predColorLanguage).Dump();

The code works in VS2008, compile and produce the correct result set, but in LinqPad, I've the following error:

NotSupportedException: The overload query operator 'Any' used is not Supported.

How can I see the generated SQL if LINQPad fails?

EDIT

If I write

var predColorLanguage = PredicateBuilder.True<ColorLanguage>();

predColorLanguage = predColorLanguage.And(c => c.IdColorEntity.Products.Any((p => p.IsComplete));

ColorLanguages.Where(predColorLanguage).Dump();

works... WTF?

As you're using LINQKit, you can make this work by calling Compile() on the expression that feeds the EntitySet, and then calling AsExpandable() on the main query:

var predProduct = PredicateBuilder.True<Product>();
var predColorLanguage = PredicateBuilder.True<ColorLanguage>();

predProduct = predProduct.And(p => p.IsComplete);

predColorLanguage = predColorLanguage.And (
  c => c.IdColorEntity.Products.Any(predProduct.Compile()));

ColorLanguages.AsExpandable().Where(predColorLanguage).Dump();

As explained in the LINQKit article, the Compile method never actually runs: AsExpandable strips it out and modifies the expression tree so that it works with LINQ to SQL.
