Hi Jan and Jon,
I was hoping to make mention to this tool in my (very soon) MicroStation CONNECT Edition Update 5 Release
Announcement a little later today. Hint, hint - the MSCE SDK U5 is now released - VS2015/.NET 4.6.1.
Feel free to download the latest (CONNECT) ECSchema Editor. Please note the first release provides read-only schema access, where future releases will provide more features and capabilities along with read-write schema access.
HTH,
Bob
