Answer 1

First, download Font Awesome, extract the ZIP file and copy fonts/fontawesome-webfont.ttf into a Fonts folder in your solution. Set the Build Action in the properties to Resource if it isn’t already
Next, add a Style to the Resources in App.xaml. Don’t forget the # at the front of the font name and remember to use the internal name of the font, not the name of the file. To check the name of the font, just double click on the font file and it will open in the Windows Font Viewer. The font name will be at the top.
<Application.resources>
<FontFamily x:Key="FontAwesome">/Fonts/fontawesome-webfont.ttf#FontAwesome</FontFamily>
</Application.resources>
Open MainWindow.xaml and replace the grid with below snippet:
<Grid VerticalAlignment="Center" HorizontalAlignment="Center">
<StackPanel Orientation="Horizontal" >
<TextBlock Text="I" FontSize="32" Margin="10" VerticalAlignment="Center"></TextBlock>
<TextBlock x:Name="tbFontAwesome" Text="" FontFamily="{StaticResource FontAwesome}" Foreground="Red" FontSize="32" Margin="10" VerticalAlignment="Center"></TextBlock>
<TextBlock Text="Font Awesome" FontSize="32" Margin="10" VerticalAlignment="Center"></TextBlock>
</StackPanel>
</Grid>
Notice "Text" property of "tbFontAwesome" textblock, its the Unicode for Heart.

To extend the accepted answer because it's somewhat out of date and missing information, here's what I did:
Download FontAwesome
Unzip the archive
Inside the unzipped folder, under the use-on-desktop folder, locate the version you want. N.B. Solid has the most icons free; some icons require a Pro payment for Regular and Light versions.
For me, this was Font Awesome 5 Free-Solid-900.otf.
Following the accepted answer and most tutorials, first create a sub-folder in your C# project named Fonts. Paste the fonts file inside this folder.
I renamed this file FontAwesome.otf for brevity
Set the properties of this file:
Build Action: Resource
Copy to Output Directory: Copy if newer/Copy always
In your App.xaml <Application.Resources> or other <ResourceDictionary>, insert:
<FontFamily x:Key="FontAwesome">/YOUR_PROJECT_NAME;component/Fonts/FontAwesome.otf#Font Awesome 5 Free Solid</FontFamily>
Replace YOUR_PROJECT_NAME with your project name. I include this because it is needed should you use MergedDictionaries across projects.
If you did not place the file in a project sub-folder Fonts, rename or omit this part of the path.
Check that the filename matches: replace FontAwesome.otf with the filename (or rename the file itself).
Check the internal font name. You can do this by following the accepted answer. (Open the .otf or .tff file from explorer to start Windows Font Viewer, copy the font name).
Replace the Font Awesome 5 Free Solid with the font name (after the #).
Do not install the font otherwise you cannot verify that you have followed these steps correctly and the font may not work across computers that do not have the font installed.

I know this is an old question, and this option may not have been available to you at the time, so I thought I would provide an updated method for anyone who stumbles across this. I recommend you install the NuGet package 'FontAwesome5' from here:
FontAwesome5 on NuGet.org
or search "fontawesome5" in Visual Studio's built-in NuGet Package Manager window:
Tools > NuGet Package Manager > Manage NuGet Packages for Solution...
-it is usually the top result when using this exact search term.
Then simply add the following namespace to your XAML document:
xmlns:fa5="http://schemas.fontawesome.com/icons/"
and then you should find relative ease in adding icons to your project. For example:
<fa5:ImageAwesome Icon="Solid_ExclamationTriangle" Foreground="#FFFF7400"/>
or
<fa5:FontAwesome Icon="Solid_ExclamationTriangle" Foreground="#FFFF7400"/>
And the beauty of this is that IntelliSense will show you a list of all available icons, saving you the hassle of going to the website to search them up.

Answer 4

You could as well manually select FontAwesome from the FontFamily property of the TextBlock.That will solve the problem.
If FontAwesome is not among the list of fonts then you probably need to import the font file just like the first answer suggested.
