Does VS2015 have any restriction regarding developing Skype for business (Lync 2013 SDK) applications?
When I try to install the Lync 2013 SDK I get an error saying "Microsoft Visual Studio 2010 SP1 or higher not found."
Do I need a Enterprise version?
this problem related to MS bug. You have to unpack it and try to install 64 or 86 msi package.
There are no restrictions. I developed my first application in C# and the Lync 2013 SDK using Visual Studio 2015 Community Edition.
