update 3

this being caused post-build action included uses ilmerge. see here more details

update2

it seems not directly caused adding command-line support, still don't know did cause it. see so question more details.

update

after making below changes allow command-line support, cannot step through program message on breakpoints:

the breakpoint not hit. no symbols have been loaded document

i checked this answer , found missing file microsoft.visualstudio.debugger.runtime.pdb have no idea has gone ..

is there reason why happen because of app.xaml update?

---

i have wpf application need implement command-line arguments.

following answer @ this question, amended app.xaml remove startupuri attribute:

<application x:class="wpffiledeleter.app"              xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"              xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"              xmlns:local="clr-namespace:wpffiledeleter"              >         <application.resources>     </application.resources> </application> 

i added override method app.xaml.cs:

protected override void onstartup(startupeventargs e) {     base.onstartup(e);      e.args.contains("mytriggerarg")             {             // stuff     } } 

but after inserting break-point @ top of onstartup , debugging application in visual studio, hangs in ready state never allows me step through program.

i tried following values startupuri:

startupuri = "app.xaml" startupuri = "app.xaml.cs" startupuri = "app.xaml.cs.onstartup" 

but application throws "cannot locate resource" ioexception

according ethicallogics's answer, enough define startup parameter in app_start event handler. if delete starupuri xaml need define somethingelse in sratup handler instead of that

how start wpf based on arguments
