There's a lot of magic numbers in this code. It'd be good to pull these out as constants and add comments explaining what they're doing.

Would be good to add an interface for this, and use the dependency injection framework to inject it into ReactComponent. That way, anyone can swap out the implementation if they want to (eg. if they want the old one back).

(see AssemblyRegistration.cs, use .AsSingleton())

Nice idea, i can inject it to ReactEnvironment and create property IReactIdGenerator (like IBabel) and call it from constructor in ReactComponent like "environment.ReactIdGenerator.Generate(...)"

ok!, const will be inlined without overhead 👍

You can pass it in the constructor for ReactComponent rather than adding a
property to ReactEnvironment

Ugh, sorry. Missed this one. There is no XML comment for this type which is generating a warning at build time.
