Summary of the Kit according to MSDN :
This kit is for .NET based developers who want to ramp up and build on the Microsoft Dynamics CRM platform. Microsoft Dynamics CRM 4.0 uses familiar components such as Web Service endpoints, Windows Workflow Foundation, SSRS reporting, and more; making it a general purpose platform for any line-of-business applications. Developers can use their existing .NET skills to take advantage of various features of the Microsoft Dynamics CRM platform. This kit drills into the details of such development and explains how developers can connect, extend, and embed with the Microsoft Dynamics CRM platform. It includes presentations, hands-on labs, and a VPC environment for practicing. This content was delivered earlier as part of the Metro Early Adopter initiative and the video recordings of the ramp-up presentations are included as well.
Familiarity with the .NET Framework, Microsoft Visual C#, Jscript, Microsoft SQL Server and general Web development is recommended.
