Packaging Fonts with Applications - WPF .NET Framework | Microsoft Docs[^]:

In order to reference font resource items from code, you must supply a two-part font resource reference: the base uniform resource identifier (URI); and the font location reference.

<Window.Resources>
    <Style x:Key="Foo">
        <Setter Property="TextElement.FontFamily" Value="pack://application:,,,/Main;component/Fonts/#MyFont" />
    </Style>
    <Style x:Key="Bar">
        <Setter Property="TextElement.FontFamily" Value="./Fonts/#MyFont" />
    </Style>
    <FontFamily x:Key="Baz">./Fonts/#MyFont</FontFamily>
</Window.Resources>

<StackPanel Orientation="Vertical">
     <TextBlock Text="" Style="{StaticResource Foo}" />
     <TextBlock Text="" Style="{StaticResource Bar}" />
     <TextBlock Text="" FontFamily="{StaticResource Baz}" />
     <TextBlock FontFamily="Segoe MDL2 Assets" Text="" />
     <TextBlock x:Name="txt1" />
     <TextBlock x:Name="txt2" />
 </StackPanel>

private void Window_Loaded(object sender, RoutedEventArgs e)
{
    txt1.FontFamily = new FontFamily("pack://application:,,,/Main;component/Fonts/#MyFont");
    txt1.FontFamily = new FontFamily(new Uri("pack://application:,,,/Fonts/"), "./#MyFont");
    txt1.FontFamily = new FontFamily("MyFont");
    txt1.Text = "\xe905";
}

You can tell the debugger which exceptions or sets of exceptions to break on, and at which point you want the debugger to break (that is, pause in the debugger)

an exception occurs that you aren't handling (and that is in the "break on this exception" list your project has set)

myDataTable = new DataTable();
myDataTable.Columns.Add("C1");
myDataTable.Columns.Add("C2");
myDataTable.Columns[0].Caption = "A new caption";
myDataGridView.Columns.Clear();
myDataGridView.DataSource = myDataTable;
for (int i = 0; i < myDataTable.Columns.Count; i++)
    {
    myDataGridView.Columns[i].HeaderText = myDataTable.Columns[i].Caption;
    }

<asp:Button ID="Button1" runat="server" OnClick="Button1_Click" Text="Button" />
