Be aware : Team Foundation Server 2015 Upgrade can take a long time

With the release of Team Foundation Server 2015, it’s time to upgrade our existing TFS 2013 environments. One warning before you start, upgrading to TFS 2015 can take a long time(depending on the size of your database), a lot longer than upgrading previous versions. The reason for this is that TFS 2015 includes schema changes to a large number of tables in order to support renaming team projects.

If you want to minimize downtime, it is recommended to use TfsPreUpgrade.exe, a small tool that does the most expensive parts of the work to upgrade to TFS 2015 while your TFS 2013 deployment is still online. TfsPreUpgrade.exe works by creating new copies of the tables most impacted by the schema changes present in TFS 2015 and then migrating data from the original tables to the new copies. As TfsPreUpgrade.exe adds some triggers behind the scenes, it can have a negative impact on performance. So only run it when you will upgrade TFS in the near future.

Remark: TfsPreUpgrade.exe can provide a rough estimate of how long it will take to execute by running the Estimate command.

Podman– Command execution failed with exit code 125

After updating WSL on one of the developer machines, Podman failed to work. When we took a look through Podman Desktop, we noticed that Podman had stopped running and returned the following error message: Error: Command execution failed with exit code 125 Here are the steps we tried to fix the issue: We started by running podman info to get some extra details on what could be wrong: >podman info OS: windows/amd64 provider: wsl version: 5.3.1 Cannot connect to Podman. Please verify your connection to the Linux system using `podman system connection list`, or try `podman machine init` and `podman machine start` to manage a new Linux VM Error: unable to connect to Podman socket: failed to connect: dial tcp 127.0.0.1:2655: connectex: No connection could be made because the target machine actively refused it. That makes sense as the podman VM was not running. Let’s check the VM: >podman machine list NAME         ...

VS Code Planning mode

After the introduction of Plan mode in Visual Studio , it now also found its way into VS Code. Planning mode, or as I like to call it 'Hannibal mode', extends GitHub Copilot's Agent Mode capabilities to handle larger, multi-step coding tasks with a structured approach. Instead of jumping straight into code generation, Planning mode creates a detailed execution plan. If you want more details, have a look at my previous post . Putting plan mode into action VS Code takes a different approach compared to Visual Studio when using plan mode. Instead of a configuration setting that you can activate but have limited control over, planning is available as a separate chat mode/agent: I like this approach better than how Visual Studio does it as you have explicit control when plan mode is activated. Instead of immediately diving into execution, the plan agent creates a plan and asks some follow up questions: You can further edit the plan by clicking on ‘Open in Editor’: ...
