Queryable Extensions missing Where<T> with LambdaExpression

[jogibear9988]

would it be possible to add a signature like this

public static IQueryable<TSource> Where<TSource>([NotNull] this IQueryable<TSource> source, [NotNull] LambdaExpression lambda)

Why do you want to add such a signature? You could cast the LambdaExpression to the appropriate type:

Expression<Func<int, bool>> expr = x => x % 3 == 0;
LambdaExpression lmbd = expr;
var lst = Enumerable.Range(1, 100);
var qry = lst.AsQueryable().Where((Expression<Func<int,bool>>)lmbd);

I've a IQueryableT, but for Perfromance I have a preparsed Expression, so I will not use Where(String), instead I will use Where(Lambda), and so I have to cast the IQueryable before I could call ToList

[zspitz]

I'm still not following. You have an IQueryable<T>? What happens when you cast the LambdaExpression to Expression<Func<T, bool>>?
