Last summer Telerik released the Oslo Comparison and Migration Tool. It is a tool that is available free for the community. It allows you to compare two Microsoft code named “M” files, see a visual diff, and then merge the results. (M is the code name for a new data modeling language from Microsoft.)

Telerik has expanded the tool to allow comparison of items in the SQL Server “Repository” and then do the same visualdiff and them merge the schema. Developers who have been playing with the M language and repository will find it very useful to have a tool that will allow comparisons and migrations, since the requirements of our applications are always changing! :) Pretty cool.

Just a note: Telerik will be updating the tool as soon as Microsoft makes some “M” and SQL Server “Repository” related announcements next week at PDC. Stay tuned!
