It&#x27;s gotten better (especially recently), but Xamarin Studio tends to be pretty buggy--  I&#x27;ve seen basic project management tasks (like adding&#x2F;moving files) crash the IDE; I&#x27;ve had syntax highlighting just stop working for files that compile fine; UI editors are slow, don&#x27;t match the feature sets of the equivalent native editors, and occasionally break backwards compatibility with themselves (seriously; had the iOS UI editor wipe out some of its own generated code and break my build a couple weeks ago).  Again, it&#x27;s nowhere near as bad as it was about a year ago, but it&#x27;s still the weak point of Xamarin&#x27;s toolset (which is, otherwise, pretty great, at least for what we&#x27;re doing with it).
