Building an ASP.Net application with C# and Entity Framework
In this post I will show you a step by step example on how to build an ASP.NET application with C# and Entity Framework. First let's try to define what EF is and why it is going to help us to create easily data-centric applications.Entity Framework is an object-relational mapping (ORM) framework for the .NET Framework.EF addresses the problem of Object-relational impedance mismatch.<img alt="" border="0" src="http://stats.wordpress.com/b.gif?host=dotnetstories.wordpress.com&blog=1661705&post=1019&subd=dotnetstories&ref=&feed=1" width="1" height="1" />

Lambda Expressions with VB.Net
Another idea-concept that is tightly linked with LINQ is LAMBDA expressions. Lambda expressions are shorthand for anonymous delegates . Basically delegates allow you to create a variable that “points” to a method. We can use this variable at any time to invoke the method.<img alt="" border="0" src="http://stats.wordpress.com/b.gif?host=dotnetstories.wordpress.com&blog=1661705&post=979&subd=dotnetstories&ref=&feed=1" width="1" height="1" />

Create a simple data-centric WPF application

SSIS is an automation tool-component that is part of SQL Server 2005 and SQL Server 2008. It replaces DTS which has been a set of tools that were useful to DBAs to import, export, and transform data.

Using the Process Component to launch applications from our .Net application
In this post I will show with a simple example how to use the Process control to launch applications from a windows form application (vb version).

Writing from a windows form to microsoft word 2007 using VSTO
In this post I would like how easy it is to use Visual Studio Tools for Office. If you have never heard before of VSTO just google it. In a few words it is a component of Visual Studio(since Visual Studio 2005) that provides a robust, .NET-based environment for building business applications using classic Office programs like Word and Excel. So that means you do not have to learn the specific Office object models, and of course you do need VBA anymore.<img alt="" border="0" src="http://stats.wordpress.com/b.gif?host=dotnetstories.wordpress.com&blog=1661705&post=751&subd=dotnetstories&ref=&feed=1" width="1" height="1" />
