The default behaviour of Visual Studio 2008 is to work with .NET 2.0, 3.0 and 3.5.

It looks like Visual Studio 2008 doesn’t allow or support applications written using .NET 1.1. Whereas if you try opening .NET 1.1 in Visual Studio 2008, then it will open the conversion wizard and will convert your .NET 1.1 to .NET 2.0.

Once your application is converted into .NET 2.0 then Visual Studio 2008 will start supporting it. As .NET 2.0 is one of the framework version which Visual Studio 2008 supports.

Introduction to LINQ

February 15th, 2008 | Posted by Vidya Vrat in LINQ - (0 Comments)

Language-Integrated Query (LINQ) is an innovation which Microsoft made with the release of Visual Studio 2008 and the .NET Framework version 3.5 that promises to revolutionize the way that developers has been working with data before the release of .NET 3.5 having LINQ feature. LINQ introduces the standard and unified concept of querying various types of data sources falling in the range of relational database, XML documents or even in-memory data structures.

LINQ offers the following advantages:

• LINQ unifies and offers the common syntax for querying any type of data source for example, you can query an XML document in the same way as you query a SQL database, an ADO.NET Dataset, an in-memory collection, or any other remote or local data source that you have chosen to get connected and accessed by using LINQ
• LINQ bridges the gap and strengthens the connection between relational data and the object-oriented world.
• LINQ speeds development time by catching many errors at compile time and have intellisense and debugging support.
• LINQ query expressions (unlike a traditional SQL statement) are strongly typed.
