Frederick .NET User Group Meeting

•6:30 PM Intro Topic: July Code Challenge Follow-up •7:00 PM Pizza/Sponsor demo •7:30 PM Main Topic: LINQ to SQL in N-Tier Applications with Steve Michelotti •Description: Creating an N-Tiered design with clear “separation of concerns” in crucial to successful solutions. However, there have been considerable misconceptions that using LINQ essentially means putting SQL statements directly in the code behinds of web pages. This presentation will create a tiered application from the ground up in order to debunk this misconception. The presentation tier for the application which will be built “on the fly” will not have any knowledge that LINQ is even being used behind the scenes in the data layer. Rather than simple CRUD operations on a single row, the presentation will highlight real-world scenarios with complex objects (e.g., parent/child relationships). The presentation will first show out of the box LINQ auto-generated SQL and then, in minutes, switch to all stored procedures in order to examine the differences. Throughout the talk, the “gotchas” for building N-Tiered LINQ applications will be presented with their appropriate solutions. •Speaker Bio: Steve Michelotti, MSCD, MCPD, MCT is a consultant for Applied Information Sciences.
