Siliverlight 4 tools for vs2010(silverligh4_tools.exe): sl4 SDK, Ria service, etc.

Silverlight 4 Toolkit

Riaservicestoolkit

Project template business application

This template contains the basic application framework of membership.

Template project directory structure

Server:

Dto: objects used for transmission on the server and client

Shared: used for sharing between the server and the client.Code

Resources:

Contains localized resource files [shared by connecting to the client and server]

Services

Domain service class: a service generated based on the WCF Ria services framework

Client:

The name is clear
