I realize there are differences between fields and auto-props when using certain other features, but from a design perspective, these are identical within an assembly:

  public int Foo { get; set; }
  public int Bar;

Java has absolutely made important improvements, and there are even more impressive ones on the horizon. In particular you should look at Project Loom, which is Java’s answer to async/await. It’s not finished yet because the design is much more general and novel, and it avoids the “function color” problem that async/await has. It’s inspired in part by Erlang/BEAM’s green threading system.

You might also look at the JDK flight recorder, which is an amazing feature that .NET doesn't have. The Java perspective is adding complexity to the runtime fiest instead of the language.
