I'm loving Rider so far, already far superior to Visual Studio in my opinion. One feature I've really missed using VS with Resharper is the Evaluate Expression function in debug mode, VS's Imediate window is a very poor relation. Unfortunately this feature doesn't seem to be working for me in Rider, are you aware of that, or should it be working?
At the moment when I click on the "evaluate expression" button, nothing happens. I hope this feature will be available in a later version, please let me know if I can provide any useful information to help you get it working
