Microsoft embraced Java at first. There was a moment in which there was a Microsoft JVM. But Sun Microsystems did not like how Microsoft was engaging Java, so they had a legal battle from 1997 to 2001. Microsoft licensed some patents from Sun, and diverted its effort into .NET. C# 1.0 was very much like Java, but over time it evolved into a completely different language focused on market demands.
