.NET training
.NET Training Overview
In this course, you’ll learn to use the exciting new .NET Framework 3.5 feature, Language Integrated Query (LINQ) to easily create complex data-independent queries. In addition, you’ll learn about the new language features added to Visual Basic in Visual Studio 2008 in order to make LINQ possible. You’ll start by working through a quick overview of LINQ, and how it applies to working with collections of objects, retrieving data stored in SQL Server, and creating XML content. Subsequent topics introduce new LINQ-oriented language features, LINQ to Objects, LINQ to DataSets, LINQ to SQL, LINQ to XML, and LINQ to Entities. By the time you’ve completed the course, you’ll have a good understanding of now only how to construct LINQ queries to work with data, but also how to use the features added to Visual Basic that support LINQ.
.NET Training Prerequisites
A good working knowledge of .NET in general and more specifically, with programming ADO.NET. Please note that this course does not cover the fundamentals of Visual Studio 2008 or .NET Framework.
.NET Training Audience
NET programmers interested in learning the fundamentals of LINQ.
