Unsupported .NET Framework Features
The following features, which may be supported by other languages targeting the .NET Framework common language runtime, are not supported in Visual J#:
Operator overloading and the .NET Framework semantics associated with operator overloading.
Implicit and explicit conversions between types using the op_Implicit and op_Explicit conversion operators.
Seamless coercion between Java-language data types and .NET Framework data types.
If a single type implements two interfaces that each require the definition of a method of the same name and signature, Visual J# does not consider these methods distinct and needing different implementations. Visual J# only supports a single code body to implement all interface methods of the same name and signature.
