We started this chapter by telling you that .NET provides a common programming model, which reduces the learning curve and increases productivity. Once you’ve learned how to do something using the classes in the .NET Framework, this knowledge will transfer to any .NET language. We then illustrated that we could write the same type of code, supporting major .NET features, in any given language. Finally, we proved to you that .NET indeed supports language integration, which is something never before possible using Microsoft platforms and tools, prior to .NET.
