Well TechEd North America 2010 is at least done. As I promised during my sessions at TechEd North America 2010, I will be posting some samples on how to create custom federation location runtime for SharePoint 2010. SharePoint 2010 includes 3 out of the box federation location runtimes. One for FAST Search, one for SharePoint Search, and one for OpenSearch compliant search providers. With this out of the box abiltiies a lot of awesome search user experiences can be done. However there are some scenarios that may warrant creating your own custom federation location runtime. Below is a list of scenarios that can come to mind.
Stay tuned for the samples later this week.
