The Microsoft Oslo platform is a new model driven development paradigm. Developers can model their applications using the new M language and store their M code on disk or move their M to the repository in order to share their models and metadata with the rest of their organization.  As applications evolve, their models evolve. Developers will now have new versions of their M code.

The Telerik Oslo Comparison and Migration Tool allows developers using “May CTP” to compare two M source code files (or groups of files) and view the differences with a Visual Diff.

Once a developer sees the differences they can determine if their new code will break their existing applications and choose to merge the files or discard the changes.

Developers can also compare M in the Microsoft Oslo repository and perform the same visual diff and merge capabilities. A future version of this tool will also allow the developers to migrate one version of the repository to another.

Download the Alpha CTP today get started, all you need is two M files! For more information you can explore the release notes and getting started guide in the /docs folder.
