[Mono-list] WCF service using JSON over Ajax possible on mono?

[Agustín Giménez]

Hi Olli.

This is not a solution but a suggestion.

If your needs are a service which communicates through http with json encoding, try servicestack, its portable and works with mono in all architectures and creates very robust REST services.

Cheers.
