If I kept track of all the hours wasted on issues due to overloads of functions called ToList() it would probably make up a sizable portion of the project budgets.

If I call ToList on a query object, it looks like I'm trying to serialize the query definition into some kind of array. That's what it *should* do with that name. Bonus if the object implements some generic enumerable interface, ToList makes it call your database, you can just toss the query into some json serializer that blocks while calling ToList for you, and people end up doing exactly this because the code turned out so much neater.

Because that's the thing. It's like people implement it because it's "neat" and the user shouldn't care about its internals. How many tears would be shed by just calling it ExecuteAsync?
