Hello Keerthana
I have tested on different computers (2), with different
Versions (14.4.0.20 and 15.1.0.37) of your components, and the result is the same. In VS 2015 I have both sfCalculator and much more, in VS 2017 just a couple of them.
VS 2017 with new installation interface I have installed only elements that I am working on routinely, then I have added a couple more features and reinstalled SyncfusionControlForUWP, unchanged, I am now reinstalling the entire computer. About the results I let You tell.
The good news is that in Reference are all drivers, just what I'm adding manually.
