Microsoft has plans to release a 64-bit version of the J# Redistributable this year. This is essentially a runtime needed to support J# applications. At the same time, they announced that J# will be discontinued and will not appear in the next version of Visual Studio.
J# is a .NET language based on Sun’s Java. It was originally released with the first version of Visual Studio.NET as a migration path for Java developers. It has never had much interest in the community for it, with most people having a strong preference for either staying with Java or using C#. Brad Wilson once wrote, "J# exists for old J++ users, NOT for modern Java users."
