Some additional notes on SVN:

running it as a server:

Please follow below to troubleshoot the following errors:

when trying to view the https repository
OPTIONS of 'https://localhost/svn/.....' could not connect to server (https://localhost)

it seems that your localhost SVN server is not running.

try creating a service as follow:
click on "start" -> "run" -> type "cmd"

type the following - but change the paths as necessary:
sc create "svnservice" binPath= "\"C:\Program Files (x86)\VisualSVN Server\bin\svnserve.exe\" --service -r c:\Users\tempuser\Documents\SVNRepositories" DisplayName= "Subversion SVN service"  start= auto

you should see the following

[SC] CreateService SUCCESS

then simply start is as follows:

sc start "svnservice"

now you can access your repositories again with the following URL:

svn://localhost/myrepository
