Visual Studio Web Service vs. Web Reference
If you are building a new project in Visual Studio targeting the 3.5 or 4.0 framework that uses the Microsoft CRM web services, and you use code snippets from a 2.0 framework project you will notice your code doesn’t compile.
If you’re like me you blindly added something called a service reference rather then a web reference.
After adding the service reference you’ll notice your code won’t compile.
You will have to choose Advanced > Add Web Reference to add a web service reference.
