ProTech is sponsoring our November meeting. A long time .NET User Group Community support, ProTech offers training and consulting services from right here in Pittsburgh.

Abstract:

Using LINQ in your .NET code is a knee-jerk reaction these days. But how many of us really understand what's really happening under the hood? What if you wanted to provide your application the ability to search on any field but wanted your code to be dynamic. Expression Trees form the basis for LINQ, and also provide you the ability to create your own dynamic queries. They are also at the core of libraries like Entity Framework and third party tools like Moq. This session will provide an overview of Expression Trees in .NET, how to use them to construct dynamic queries, and

we'll also walk through a sample application that evolves from hard-coded queries to Expression-based dynamic queries.
