Telerik has a good converter that is based on SharpDevelop that has worked pretty well over the years, though it has not been updated in years (due to it being based on SharpDevelop).
I've recently come across a roslyn based converter as well. I don't know how well it works or how well maintained it is, but as it's open source you can always fork it and update it as needed.
