Invoking event handlers in C# has always been a bit of a pain, because an event with no subscribers is usually represented as a null reference. 

In these modules, see how to build custom middleware, find out how to use advanced configuration, and work with multiple environments. Look at options that are activated in development only, explore the importance of globalization and localization, and view components.

In the February 2016 issue of MSDN Magazine, I showed how to create a custom scripting language based on the Split-And-Merge algorithm for parsing mathematical expressions in C# (msdn.com/magazine/mt632273). I called my language Customizable Scripting in C#, or CSCS. Recently, I published an E-book that provided more details about creating a custom language (bit.ly/2yijCod). Creating your own scripting language might not initially seem to be particularly useful, even though there are some interesting applications of it (for example, game cheating). I also found some applications in Unity programming.
