JVMStaticGC

Microsoft's flagship language — dominant in enterprise, game development (Unity), and Windows desktop applications. Similar to Java but with more modern features: LINQ, async/await, nullable reference types. Benchmarks show moderate verbosity with decent safety from GC and optional null checking.
