I am developing an application for windows phone and microsoft band, the application consists of several pages.
I pass parameters between pages, but the page you are methods of microsoft band and libraries, when I try to run it more than once, gives me the following problem
'microsoft.band IOException in Mbcorlib.dll'
and do not know why.
I think it is because it runs more than once, as I call it from the main and other pages, not to mention giving me
global::System.Diagnostics.Debugger.Break();
An application can have only a single, valid IBandClient instance (i.e. connection to the Band) at any given time. If you have multiple pages that each connect to the Band, and you navigate between them without first closing/disposing of the connection before the navigation, then you can expect to see Band communication errors.
Without more specific information about what those pages are doing (e.g. how they're using the Band), it is difficult to guess at the problem you are having.
