Application Initialization IIS – Log Files

I have configured the Application Initialization for a Web App running on Azure, the reason for that is to improve the “warm up”, because I have some issues with Scale-out, the instance is not ready for the connection then I got some servers errors.
There is a good doc from Microsoft about that:

Bitflag to int C#

I’m consuming a web API and I need to pass in an int value that corresponds to a bit flag. How do I calculate the int values to pass in? For instance, if I want Option B, Option E, and Option F – what would the corresponding int value be?
