This is the class for new .NET LINQ developers looking to gain understanding of the most important features found in .NET 3.5 and the new C#.NET and VB.NET language support for these new features. LINQ is now integral to .NET development. This 1-day class gets you up to speed on the LINQ technology new in .NET 3.5.

Brief Course Description: This LINQ .NET training course is a hands-on introduction and comprehensive 1-day hands-on tutorial of LINQ under .NET 3.5. LINQ can be a confusing technology; attend this course to make sense of LINQ and understand where it fits in your .NET toolbox. The course provides full coverage of LINQ. Several hands-on exercises and labs reinforce the lectures and code demonstrations.

Duration: 1 day of comprehensive .NET LINQ Training with C# .NET and VB.NET

Format: Instructor-led, hands-on; with 4 or more hands-on exercises

Prerequisites: To attend this LINQ .NET training class, strong working knowledge of .NET 2.0 concepts and facilities is required for attendance. The ideal .NET LINQ training student has attended and/or is complete command of the content from our ASP.NET 2.0 Training BOOTCAMP with C#.NET (5-day) or the ASP.NET 2.0 Training BOOTCAMP with VB.NET (5-day) . Windows forms developers using C#.NET or VB.NET under .NET 2.0 are also qualified to attend this training.

Course Materials: LINQ book totaling 300+ pages; Resource Pack with CD

Course Description Summary: : This is a fast paced, 1-day, in depth hands-on .NET LINQ training using C#.NET and VB.NET. This class is about 50% lecture with code demonstrations and about 50% lab work thereafter. The lab work includes many short exercises and several in-depth LINQ .NET training projects. The student exits this class aware of best practices in .NET LINQ and ready to build production .NET 3.5 applications incorporating the LINQ technology, using C#.NET or VB.NET.
