This morning I blogged about using LINQPad to query an XML file. Well did you know you can also query a Microsoft Dynamics CRM 2011 (in the cloud?!?) version directly from LINQPad? Pretty sweet.
The use of LINQ has become more and more prevelant in the last few years, from .NET Developers using LINQ2SQL, and just using LINQ for object queries, and everything in between (when is there going to be a LINQ2OLAP??)
Once you have that all set you can go and get your LINQ Query on.
The possibilities are pretty much endless here, but yeah, now you can run ad-hoc queries against your CRM installation, which is pretty cool. If you want more samples, install the CRM SDK and do some code diving, you will find some LINQ queries they do in the SDK, which is how I initially got the idea to try using LINQPad.
