Question

i have 2 projects in my solution (main is A.WPF and secondary is B.WPF)

when i’m trying to access variables inside my App.xaml.cs in B.WPF:

filename = ((App)Application.Current).ErrorLogFileName;

i get the following error:

Unable to cast object of type 'A.App' to type 'B.App'.

i also tried the following:

filename = ((B.App)Application.Current).ErrorLogFileName;

but still the same error…

the definition in B.App is:

private string _errorLogFileName = "error log.xml";

public string ErrorLogFileName
{
    get { return _errorLogFileName; }
}

please assist…

Looks like you need to do:

filename = ((A.App)Application.Current).ErrorLogFileName;

The error is saying the type is A.App, yet in both cases you are trying to cast to B.App.

There can only be one current application also.
