In this course, Mark Long introduces you to the basics of LINQ. He shows you how to get started with LINQ, how LINQ works and with lots of programming demos, he takes you step by step through using LINQ to query Objects, SQL Server and XML documents. To begin learning today, simply click on the movie links.
Language Integrated Query is a new programming feature set that Microsoft officially introduced as part of the 3.5 release version of the .NET Framwork. LINQ brings the world of data queries into the .NET Framework and makes the query itself part of the development environemnt. The result is that developers can now access data from diverse sources using queries with very similar syntax. LINQ provides Intellisense, compiler hints and assistance as well as making data queries happen with few lines of code that is easier to read and understand.
Welcome to the Virtual Training Company presentation of Introduction to Microsoft LINQ. My name's Mark Long and I'm very happy to be here bringing this course to you. In this course, we're going to talk about Microsoft LINQ and this is a set of programming language extensions if you will that Microsoft added to VB.NET and C# in the Visual Studio 2008 release and that course includes, coincides with the Microsoft .NET Framework 3.5 version. Now the idea behind Microsoft LINQ is to create some sort of standardized query environment pulling data from virtually any data source, the original idea was that we put all of our data in the databases and pull them out, concurrency, security access, a lot of things began to cause problems. Then of course that pesky thing called real life that caused the most problems and that is the explosion of the Internet, the use of hierarchical data like XML, the fact that our data is strung across access databases, other people's databases besides SQL server, e-mails, Excel spreadsheets and the list just goes on and on and on and it's just not possible to basically coagulate all of that data into a single central data storage that's not going to happen. So Microsoft has come up with the idea of let's make our language do the work and by doing so we can also help the programmer to stay with the one language development environment. So anyway, let's jump into the course, start to take apart Microsoft.LINQ we'll do a lot of examples and programming here, get you going and you'll be as dangerous on LINQ as you are on all these other things that you're doing so thanks for joining me. Let's get started.
