I've mostly worked on the server side of things for the last few years but last year I decided to dip into mobile. I felt disappointed after trying MonoDevelop as I found a lot of the things I had really appreciated in server development missing or inadequate. Things like a proper package manager and easy integration with CI servers. I just got NuGet to work last month, after trying it infrequently over a couple of months. xbuild, I never got to work properly, sure I was able to run unit tests inside MonoDevelop but my expectations were a bit higher.

Meanwhile, over in Javaville, I can do just about anything Android related my heart desires with Maven and even CocoaPods in its infancy was a better experience than NuGet. Just my 2 cents.
