PUBLIC SECTOR WEBCAST: Introduction to LINQ + LINQ to SQL (June)

June 27th 2:00P-3:30P EST (11:00A-12:30P PST)

Modern applications operate on data in several different forms: Relational tables, XML documents, and in-memory objects. Each of these domains can have profound differences in semantics, data types, and capabilities, and much of the complexity in today’s applications is the result of these mis-matches. In this talk, we will explain how the Orcas release of Visual Studio aims to unify the programming models through LINQ capabilities in C# and Visual Basic, a strongly typed data access framework, and an innovative Application Programming Interface (API) for manipulating and querying XML.

Database-centric applications have traditionally had to rely on two distinct programming languages: one for the database and one for the application. In the second part of this talk we will introduce LINQ to SQL, a component of the LINQ project designed to help integrate relational data and queries with C# and Visual Basic. LINQ to SQL enables developers to express queries and updates in terms of their local programming language without sacrificing the server-side execution model of today’s high-performance SQL-based approaches. Using these advances, database queries that previously were stored as opaque strings now benefit from static type checking, CLR metadata, design-time type inference, and of course IntelliSense. LINQ to SQL also supports a rich update capability that lets you save changes to an object graph back to the database using optimistic concurrency or transactions.
