The ?BDS? symbol is defined, the code sample is:

---

1. if DEVENV
   

return _instance ?? (_instance = new DevenvSolutionHelper());

1. elif BDS
   

return _instance ?? (_instance = new BdsSolutionHelper());

1. else
   
2. error There is no IDE selected for support, consider defining one of the symbols on the project.
   
3. endif
   

---

Of these three choices, R# displays the second and the third as active (BDS and #else) by color, and highlights the #error tag as an error. C# compiler passes the compilation and from its point of view only the second choice is active.

I think that even in the current R# parsign mode for the defines this case should work OK, as it does for the two-choice case.
