How to correctly add InstallShield-Projects under version control with VisualSVN in a VS-Solution

Question

I'm currently switching from TFS to VisualSVN (client v5.1.3 / server v3.5.1).

In TFS the InstallShieldLE-Projects were also automatically under source control. (Marked with the TFS specific signs).
After unbinding from TFS and adding the solution to VisualSVN
by selecting VisualSVN -> Add Solution to Subversion in VS2015, they are not included by default anymore (missing traffic lights status icons for ISLE-Projects). I'm also missing the "Add to subversion"-Option in the context menu for this kind of projects in VS2015.

I know i'm able to add files manually via the TortoiseSVN-Context menu in windows explorer or CMD-line. But isn't there a "built in way" to do this? Because i dont want to take care by myself, if all files included to subversion correctly all the time...

Answer 1

Adding the the following files manually, via the SVN-Contextmenu in Windows-Explorer did the trick. (Maybe some configuration changes at the VisualSVN-VS-Plugin will do this automatically)

After adding the following files manually from the InstallShield-Project-Folder:

• [ProjectName].isl
• [ProjectName].isproj

...the project seems to be correctly bound in VS:
