WPF XAML Parse Exception?

Question

I was working on a WPF application, and it was running fine. I commented out an if check to test something in a utility class, and all of a sudden my program stopped running due to a XAML Parse Exception. The part of the XAML that it points to is the opening tag and to this attribute:

xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"

The full tag is this:

<Window x:Class="MyApplication.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="MainWindow" Height="Auto" Width="Auto" WindowStartupLocation="CenterScreen" Topmost="False" KeyUp="KeyUpCheck" SizeToContent="WidthAndHeight" ResizeMode="NoResize" mc:Ignorable="d" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" d:DesignWidth="441" d:DesignHeight="319">

The exact error is this:

'The invocation of the constructor on type 'MyApplication.MainWindow' that matches the specified binding constraints threw an exception.' Line number '4' and line position '291'.

The attribute is what is generated when I resize the form in the viewport. I'm completely clueless as to why it's giving me this error. Any ideas?
