Prevent the application from freezing

If the extension executes a process that takes a long time, the application may appear to freeze. The following code allows you to draw the UI while the extension is running.

using System.Windows.Threading; 

///<summary> 
///DoEvents 
///</summary> 
void DoEvents() 
{ 
var frame = new DispatcherFrame(); 

var callback = new DispatcherOperationCallback(obj => 
{ 
((DispatcherFrame)obj).Continue = false; 
return null; 
}); 

Dispatcher.CurrentDispatcher.BeginInvoke(DispatcherPriority.Background, callback, frame); 
Dispatcher.PushFrame(frame); 
} 

void SomeCommand(ICommandContext c, ICommandParams p) 
{ 
for ( var i=0;i<100; i++) 
{ 
//Do some processing 
... 

//Update the application screen 
DoEvents(); 
} 
} 

Caution

Instead of blocking the user interface, it is possible to operate the screen, which may result in unexpected behavior, so please use with caution.
