The January Orcas CTP went out last night about 8:30 Pacific time. It is available both as a regular install, and on a virtual machine. I have not had a chance to install it yet, so I can't give too many details of exactly what is available. However, most of the builds I tested around the time the code froze for its release had good support for LINQ to Objects and only shaky support for Linq to SQL. The release notes for the product are, however, more sanguine on Linq To SQL and Linq to Entities support, and certainly there has been good support for those features in the internal builds I've seen in the last few days. The current internal builds are all targeted at the February CTP.

Over the last few weeks I've spent a considerable amount of time porting code from the May LINQ CTP to the current builds of Orcas. Most of the major LINQAPI's stayed the same during that time frame, but the details changed on several occasions. Please see my Notes on January CTP for a description of the experiences I encountered while porting the code. I give a blow by blow for many of the minor API changes.

There was more snow last and so things are quiet here in the office, with many folks still at home. That should give me time to install the CTP on a Vista machine and confirm the details on the Linq To SQL code. I'll post more later in the day or tomorrow.
