Issues Debugging MVVM Bindings in Visual Studio 2010?

Question

I'm developing an application in Visual Studio using MVVM Light and Ninject. Unfortunately, when I try to debug this application and there's a problem in one of my ViewModels, instead of actually debugging the code, I get something like this:

This is rather useless and impossible to debug. Now, if I know where the error is or have an idea, I can insert breakpoints there in the code and Visual Studio will show the correct info, but I don't always know where the error is. I can't just breakpoint every line of code in the application. Is there a way to force Visual Studio to look past the UI and debug the actual code?

Answer 1

There is no need to set the owner of the application main window.

The correct way to set the owner of a window in XAML is as follows

<object>
  <object.Owner>
    <Window .../>
  </object.Owner>
</object>

alternatively you can set it from code behind like this

// Create a window and make this window its owner
Window ownedWindow = new Window();
ownedWindow.Owner = this;
ownedWindow.Show();

The way you have done WPF tries to convert the string "Auto_Calibrator_v0._05.MainWindow" to window object which is not possible unless you have a type converter.

I am not able to view the error please make it large or type it in text format. This is from my page.

<UserControl x:Class="Retail.View.Settings.ShopSetting"

             xmlns:d="http://schemas.microsoft.com/expression/blend/2008" 
             mc:Ignorable="d"      `
