A Visual Studio extension that auto loads Scc providers depending on presence of reserved repository file or directories. Supported Scc providers are:

• AnkhSVN (Subversion, default);
• VisualSVN (Subversion);
• Visual Studio Tools for Git (Git, default);
• Git Source Control Provider (Git);
• HgSccPackage (mercurial, default);
• VisualHG (mercurial);
• Perforce (thanks Iurii Zhogoliev).

More providers can be added, provided they are regular Scc providers and there exists an easy way to detect proper RCS type by checking file or directories presence starting from solution root directory.

It supports all Visual Studio versions from 2010 to 2017. License is MIT.

SccAutoSwitcher offers a very simple options dialog page allowing to change the default Scc provider loading priority for different RCS types. To explain allowed values, let's take Suversion Scc providers as an example:

• Default: means AnkhSvn is loaded first, if it's found, otherwise the latter is loaded.
• AnkhSvn: will always try to load AnkhSvn, regardless of extension(s) install status;
• VisualSvn: will always try to load VisualSvn, regardless of extension(s) install status;
• Disabled: won't try to switch Scc provider for Subversion repositories, effectively disabling SccAutoSwitcher for this RCS.

No popular Scc provider seems to enforce itself using the same mechanism SccAutoSwitcher uses to load them. This may be a restriction of VisualStudio. enforced for Scc provider extensions only, or a misunderstanding on the used API[1]. Regardless of the motivation, this actually leaves doors open for competition, as multiple Scc providers can be installed for the same RCS type and there's no contention during solution loading: this is the specific moment when SccAutoSwitcher intervenes, acting as an arbitrator for the different Scc providers and efficiently loading the correct or favourite provider.
