WPF - TextBlock - Format Text Programmatically

Question

In the TextBlock object you can format the text in the XAML like this:

<TextBlock>
    <Bold>bold text</Bold> random non bold next
</TextBlock>

How do you do the "Bold" tags programmatically?

I tried just putting them in the text property and it just printed them out (the tags were printed as text).

Visual Basic Version:

Dim tb As New TextBlock

Dim b As New Bold
b.Inlines.Add(New Run("bold text"))

tb.Inlines.Add(b)
tb.Inlines.Add(New Run("random non bold text"))

C# Version:

TextBlock tb = new TextBlock();
var bold = new Bold(new Run("Bold Text"));
tb.Inlines.Add(bold);

var normal = new Run("Normal Text"));
tb.Inlines.Add(normal);
