Running .Net application by App()

[bartek618]

I know how to run .Net executable by MainWindow() constructor but I have some resources defined in App.xaml and MainWindow() doesn't run without them. How to run application starting with App() constructor? Also I need to pass some parameters into MainWindow().

I assume you're talking about a WPF app.

WPF apps are normally launched via the static entry point App.Main() method, just like Windows Forms and Console apps (which by default specify a Main method in the arbitrarily named Program class).

The contents of this method is normally generated for you by the compiler, and typically creates an instance of the App class, calls it's InitializeComponent() method followed by the Run() method. The default implementation of the InitializeComponent() method is parse your App.xaml, determine the startup Window class (in your case, MainWindow.xaml) so that Run() method can startup the Dispatcher for the message loop  and load your window class.

Try calling the static Main() method in your assembly.

The method is static - you don't need a constructor node so try without that. 

The exception text isn't in a language I'm familiar with but I suspect it may be due to which thread is executing the clumps. Try also setting the VI execution properties for the enclosing VI to run in the UI thread only.

I get an exception that Assembly.GetEntryAssembly() returns null. Vi execution is set to UI. Any idea what's going on?

 

Assembly.GetEntryAssembly() returns null. Set the Application.ResourceAssembly property or use the pack://application:,,,/assemblyname;component/
