The text displayed in an XAML button is set by the Content property (or so I believe).
What is the correct way to do something like....

if mButton.Content = "Press Me" then

The above doesn't work :(

Not sure what you're trying to do...  what you have above appears to be trying to set the text of the button in an "if" statement.

This would set the text on the button:
mButton.Content = "Press me";

This would test to see if the text on the button is "Press me";
if(mButton.Content == "Press Me")
{ // do something }

I'm trying to test if the button's text is "Press Me" but it Errors as

Error      1      Requested operation is not available because the runtime library function 'Microsoft.VisualBasic.CompilerServices.Operators.ConditionalCompareObjectEqual' is not defined.

Ah, VB, not C#...  Not my specialty, but...

Try this:
if mButton.Text.Equals("Press Me") then

Or
if String.Equals(mButton.Text, "Press Me") then

There is no .text on an xaml button.  It's called Content as far as I can see.

Content holds an object. You have to call a .ToString() on it.

Try this:

if mButton.Content.ToString() = "Press Me" then

You are correct...  being that I don't do VB (other than occasionally read it), I tested the code under forms which uses .Text...  Content is correct for XAML so:

If mButton.Content.Equals("Press Me") Then
     code goes here
End If
