Slightly Confusing documentation

in the c# sample of how to configure the lazy loading proxies i was presented with this

AddDbContext(
b => b.UseLazyLoadingProxies()
.UseSqlServer(myConnectionString));

The problem here is not everyone learning c# knows about Func and Action delegates so to call a delegate "b" here could be confusing to some whereas all the samples on the internet uses "options" as the parameter to the delegate instead of "b". I myself got confused for a moment thinking "what does "b" refer to?" It took me a couple of seconds to get it.
