T4 template that creates Typescript type definitions for all your Signalr hubs. If you have C# interface named "I<hubName>Client", a TS interface will be generated for the hub's client too.If you turn on XML documentation in your build, XMLDoc comments will be picked up.Licensed with http://www.apache.org/licenses/LICENSE-2.0

3 years later...if anyone wants an alternative to T4 templates, I wrote a command line tool based off the code in this gist:
You can add it as a post-build step which makes build server integration a little easier (also we were having problems with conflicting version of JSON.NET).
