In the previous discussion, you’ve seen how to use a single language, in our case C#, to build a complete application. This seldom is the case in a real-world environment where libraries from various sources need to be combined to provide an end-to-end solution to the problem at hand. In fact, our use of BCL types like
System.Console is a good example of such a scenario. Although those happen to be written in C# too, as most of the code in BCL is, that’s not a requirement at all thanks to the cross-language capabilities provided by the CLR. However, consuming libraries is just the tip of the language interoperability iceberg. Richer capabilities, such as extending existing types in a different language than ...
