In order to prepare for multi-server connectivity, I've updated ApiClient with a new ConnectionManager class. Before we get to that, you can upgrade the library with full compatibility by making the following changes:

 

1. Adjust constructor params (see github wiki. fewer params now).
2. Change HttpResponseReceived event to RemoteLoggedOut. This is a friendlier overload to indicate your session was logged out remotely by the server.

Everyone should do this just to start with. jitterjames, and nullpointer, this is possibly all you will need to do.

 

 

Connection Manager

 

Instead of creating an ApiClient instance at your application's entry point, you will instead want to create a ConnectionManager. I've written it all up on the wiki so I'm not going to rehash it all here, but suffice to say, all you need to do is call ConnectionManager.Connect, and that will create your ApiClient instance for you. It will also return a State value indicidating the result:

 

• Unavailable (user has to enter connection info manually)
• ServerSignIn (connected to server but user needs to login)
• SignedIn (connected, signed in, and ready to browse using previously saved credentials)

 

Connection Manager Features:

 

• Automatic opening & closing of web sockets at appropriate times
• Automatic saving and validation of credentials
• Server discovery
• Wake on lan
• Automatic LAN/WAN fallback (this will need testing)

 

Note: The model has interfaces - IApiClient, IConnectionManager, and others in case you want to shield these dependencies from certain areas of your apps.

Aphid - I have handled this for MBT, but I imagine you'll have to do it separately for your branch as well.

[Aphid 212]

The logic for showing the login screen might differ a little, but otherwise I expect whatever you implement will apply to both branches.

[Luke 37068]

Definitely. But if you look at the last paragraph on the wiki page, that is the hard part. It's not a requirement that every app do that just yet, so you can certainly wait if you need to. But I figured I'd move ahead with MBT so that I can hash it out.

I shall migrate to the connection manager logic for my next release.

[Luke 37068]

Thanks Armand. Let me know if you need anything.

for some reason i'm getting the following error, after implementing the connection manager logic.

Right after I call ConnectionManager.Connect(CancellationToken.None).

I'm currently tracking down the issue but myabe you have an idea of what is going wrong.

[Luke 37068]

make sure you're on the latest version of the package because 7 spotted a similar issue that was fixed. if you are then let me know and i'll look again.

[Armand 21]

after the update the problem shifted to my code.. probably some async issue now on my side

[Armand 21]

Looks like ConnectionResult.ServerInfo is null when ConnectionResult.State = ConnectionState.ServerSignIn

[Luke 37068]

yup i can see it. a new nuget will be up in 5 mins.

[Luke 37068]

Based on some feedback from 7, there's a minor adjustment:

 

The State property now has ServerSelection, which means multiple servers are available and the user should be given a selection. The ServerInfo property has been changed to a list. For all the other state values it will either have 1 or 0 entries.

[Luke 37068]

There's another update up.

 

There's a new ICryptographyProvider that you have to supply as a dependency. An implementation is included for the full .net 4.5 version, but those using the PCL version will have to implement it.

 

The sample on the github wiki has been updated.
