What is a loose XAML file?

It is very similar to an HTML file that you create in Notepad and add it to your files/folders like this one:

Type in Notepad the following one line:

Hello, HTML

and now save it as TestHTML and save it as a HTML file (not the .txt extension) to your desktop. When you double click this file, your browser (IE perhaps) displays the following:

Hello, HTML
Sometimes it is also called a HTML fragment.

Likewise you can store a loose XAML file as shown:

Type the following in Notepad and save it as a file with extension .XAML to your files/folders.

http://schemas.microsoft.com/winfx/2006/xaml/presentation

" FontWeight="Bold">
Hello, XAML
 
Now open this file using IE (this is usually at C:\Program Files\Internet Explorer\iexplore.exe)

You will see the following:

Hello, XAML

For a loose XAML file you should havethe following:

•Contains only XAML (that is, no code).

•Has an appropriate namespace declaration.

•Has the .xaml file name extension.
