I'm using SocketRocket with the Xamarin wrapper you have provided. I'm filing this bug with you because I think it's more likely that the bug is with your code than theirs.

I new up an instance of the SocketRocket client per the documentation. It works fine, submits a GET request to the server, and things proceed nicely.

Then I command-home the app, wait till things time out, and bring the app up out of the background. In that case I've coded the app to reconstruct the SR client from scratch (per documentation and various examples I've found).

When I do this, it submits the same GET request to the server, but the first line of the handshake data is corrupted. It should come through as "GET HTTP 1.1" or similar. Instead, it's coming through as "<garbage>GET HTTP 1.1", where <garbage> == an ASCII rendering of some obviously unintended stuff.

If I kill the app and restart it, the request is correct. That's why I'm blaming the client and not the server.

I really don't know the problem is in the Xamarin wrapper, but frankly I can't believe this use case hasn't been hammered on by the community that's using SocketRocket. 

Here's version my version info. I'm using the latest versions of all of the libraries involved.
