Conditions with attribute comparison

When attempting to build a condition comparing to another attribute as the documentation shows, like this:

var candidate = ...
var scopeWrite = Transact.UpdateItem<JobScope>()
  .WithPrimaryKey(pk, sk)
  .WithCondition(Condition<JobScope>.OnSizeOf(js => js.Jobs).LessThan(js => js.MaxJobs))
  .On(js => js.Jobs).Insert(new HashSet<string> { candidate });

the LessThan method gives a compile error:

error CS1660: Cannot convert lambda expression to type 'Expression' because it is not a delegate type

Am I doing something wrong? The parameter is of type Expression - should this be Expression<Func<TEntity, TProperty>>?

@firenero - no problem, done.

@briananderton-il This one seems unrelated to the original API issue. And I can’t easily reproduce it. Do you mind creating a separate issue and providing some code for me to reproduce?
