  • Staying Safe and Sound Thanks to MDSD

    In this article, Andreas Kaltenbach explains how Model-Driven Software Development (MSDS) can help solving backward compatibility problems when creating a newer version of a software which can mean a new API or a new database schema that old clients cannot use. MSDS is used to negotiate the differences between versions to ease the upgrading process.

  • Fine Grained Versioning with ClickOnce

    ClickOnce makes it easy to deploy WinForms applications. But while it has some versioning support, it has no built in way to deliver different versions to different people. This makes partial rollouts to a test audience difficult. David Cooksey shows how to fine grained versioning to a ClickOnce deployment using an HttpHandler written with ASP.NET.

    Version Control for Multiple Agile Teams

    When several agile development teams work on the same codebase, how do we minimize chaos, and ensure there's a clean, releasable version at the end of every iteration? Here Henrik Kniberg outlines the scheme used in "Scrum and XP from the Trenches". This paper is not so much for version control experts as for the rest of us, who just want to learn simple and useful ways to collaborate.
