A few weeks back, I wrote a series of three articles on the topic of building SharePoint 2010 Service Applications. Today, I have updated the source code for these articles to include Powershell cmdlets for provisioning, retrieving and updating the demo service application from the command line.
The three articles and a link to download the source code solution can be found on the SharePoint Solutions' community site:
Part One – The Service Application
Part Two – The Service Application’s Admin Interface
Part Three – The WCF Service Endpoint
Part Four – The User Application Page
