Avoiding use XRMServices/2011/Organization.svc in console applications

Hello,

I am using ClientServer authentication to avoid using WS-Trust, which will be deprecated.

Before I used a connection string with the url like this:

connectionString="AuthType=Office365;Username=****;Password=*******;Url=">something.dynamics.com/.../2011"

I have noticed that the url uses another feature that is also going to be deprecated(/XRMServices/2011).

My surprise comes when using clientserver, the object that get the connection have the following property in data:

My current connection string:

connectionString="AuthType=ClientSecret; Url=something.dynamics.com;  ClientId= ********;ClientSecret=********"

I'm not sure this connection method will work when Microsoft doesn't support XRMServices/2011 this year.

Is ClientServer authentication sure for my purpose?
