Hands down, this is the accelerator that developers (at least I personally) would crave for.
CRM Accelerators: eService (ASP.NET Portal)
eService accelerator allows developers to easily create self-service customer portals built on top of ASP.NET. This accelerator utilizes an ASP.NET starter kit and several components of the ASP.NET framework including the membership provider for authentication. The out of the box functionality of eService includes the ability for customers to create cases, schedule and manage service appointments, search through KB articles, etc all from within the website.
Don’t be fooled by the name “eService”, as underneath the covers, there is an ASP.NET control suite for CRM. Each of the ASP.NET form you saw in this video is a customizable ASP.NET user control and all of its properties and settings are derived from the CRM metadata. You can hook up these controls to any entity within the CRM system and configure them fairly easily.
I’m sure this accelerator will jump start CRM development for a lot of ASP.NET developers and vice versa.
