This week, I just wondered why the Sophis R&D didn't permit to override the CSRGlobalFunctions class in C# before the 6.3 version. If you take a look at the DotNet toolkit, you will see that a CSMGlobalFunctions is defined, but no static method Register exist as for the other classes. This point was several times scrolled up to Sophis in the toolkit forums, and I know some clients who ask Sophis to provide a toolkit permitting their own implementation. Unfortunately, they don't have the code and the interface provided in C# does not implement all virtual of CSRGlobalFunctions, for instance StartPortfolioAddition which is a callback on which we can implement the agregation of results for user columns that we want to store in a cache.

For remember, the overriding of the CSRGlobalFunctions class permits to be called when the folios are calculated (StartPortfolioCalculation, EndPortfolioCalculation).

The goal of this post is to describe how to implement a C++ implementation of the CSRGlobalFunctions that permits to implement callback in C#.
