John, Are you familiar with how async pattern works? What you suggested looks great except that it won't work. The GetSize syncronous method can't be used to return a value, because to do that it'd have to execute syncronousely, rendering the whole effort useless. Since it can't return IAsyncResult as it should, because it would cause a runtime error, it retuns null (or 0 for value types). The point is to somehow make up for the absence of actual methods:
IAsyncResult BeginGetSize(string line, AsyncCallback callback, object someData); int EndResult(IAsyncResult); Code similar to your could work if you used Expression classes, but I'm resisting using them unless I have to. I appreciate your help, if you want ping me and I'll send you the actual code. I'm not going to publish it yet, since it's lacking a lot a the moment, but it is working and if anyone else wants to play with it, just drop me a line.
