Deploy and debug apps on remote targets
There are a number of ways that Visual Studio and Visual Studio Code enable you to interact with remote machines. Both can enable you to connect to a remote machine and use it as a build machine and debug your applications there. Sometimes though your target is not the same as your build machine. For example, for embedded Linux devices you will likely want to cross compiler the application on a more powerful build machine then deploy to the device for debugging. This post is going to demonstrate how to build an application locally in a Dev Container for either a Raspberry Pi 3 or 4, then deploy and debug the appl...

vcpkg Documentation Moves to Microsoft Docs Platform
vcpkg Documentation Moves to Microsoft Docs Platform As of today, the vcpkg documentation has a new home at https://learn.microsoft.com/vcpkg. This is the platform that most Microsoft documentation is hosted on and comes with many features that make it easier to search, navigate, author, and review documentation. All current vcpkg articles are now visible on the new platform. We are still in the process of removing the documentation from other locations (vcpkg.io, the main vcpkg GitHub repo, and vcpkg.readthedocs.io). We will add redirects where possible to the new home for the docs to avoid breaking existing ...
