Write your Java apps in Visual Studio.NET?
Apparently Visual MainWin allows you to write your webapps in C# and .NET and then deploy them to a J2EE server.
Visual MainWin for J2EE enables these organizations to deploy .NET and J2EE applications on a single J2EE infrastructure, eliminating the need to maintain two separate application servers or implement complex interoperability solutions between the .NET and J2EE platforms.
This product certainly won't do anything for me. I've heard that Visual Studio is a great IDE, but if I can't write Java in it - what's the point?
Then again, I'm biased. I have a friend who is a long-time Java developer. Lately, he's been developing in C# because that was the only gig he could get (in Nevada). He says that C# is a piece of sh*t compared to Java.
Update: My friend contacted me to set the record straight. To quote him, "C# is OK, its the .NET framework that sucks ass. The C# syntax is a total ripoff of Java anyways."
