Thank you for bringing this to our attention, it looks like the docs need updating. I can’t seem to find what the equivalent is, but while we look into this you can enable profiling on the default port by adding <DebugNetworkPort>9264</DebugNetworkPort> to the DebugNetworkPortList in the MicrosoftGame.Config file- it should be in the same directory as your build .exe file.
I will let you know when we find a better solution, and of course update the docs as well.
