Is Eiffel transparent in Visual Studio .NET?
Yes. Eiffel for .NET can be used in exactly the same way as classic Eiffel and no extra language constructs are required to produce applications. Since there are some elements of the .NET language which have no equivalents in Eiffel, such as the ability to define custom attributes, these have been extended to Eiffel for .NET so that the full features of .NET can be used.
