I cannot see AnkhSVN as an option under "Tools - Options - Source Control" in Visual Studio 2017. I have uninstalled and reinstalled AnkhSVN, but no effect.
Is there a way to fix this?
I came here looking for an answer to the same question. I am Running Windows 10 Enterprise and had VS2015 with AnkhSVN working before and after installing VS2017, but in VS2017 AnkhSVN was not available under SCC Plug-In Selection (even after uninstall and reinstall of the install executables downloaded from http://ankhsvn.open.collab.net, which offer registration against VS Dev15/2017).
This is what eventually worked:
So the trick I believe is to "remove program installed by MSI/EXE followed by install extension via Visual Studio VSIX".
I was also subsequently able to upgrade AnkhSVN (2.7.12815 from VSIX install), by running the downloaded EXE installer for the latest daily build (2.7.12821), after which AnkhSVN is available in both VS2015 and 2017, although I had to reselect it in 2015.
