Note that the file     scheme does not work on the compact framework  at least it doesn t with 5 0   You will need to use the following   string appDir   Path GetDirectoryName      Assembly GetExecutingAssembly   GetName   CodeBase   webBrowser1 Url   new Uri Path Combine appDir    Documentation index html

Somewhere  nearby the assembly you re going to run  Use reflection to get path to your executing assembly  then do some magic to locate your HTML file    Like this   var myAssembly   System Reflection Assembly GetEntryAssembly    var myAssemblyLocation   System IO Path GetDirectoryName a Location   var myHtmlPath   Path Combine myAssemblyLocation   my html

Do a right click- properties on the file in Visual Studio   Set the Copy to Output Directory to Copy always    Then you will be able to reference your files by using a path such as     my html html   Copy to Output Directory will put the file in the same folder as your binary dlls when the project is built   This works with any content file  even if its in a sub folder   If you use a sub folder  that too will be copied in to the bin folder so your path would then be     my subfolder my html html   In order to create a URI you can use locally  instead of served via the web   you ll need to use the file protocol  using the base directory of your binary - note  this will only work if you set the Copy to Ouptut Directory as above or the path will not be correct   This is what you need   string curDir   Directory GetCurrentDirectory    this webBrowser1 Url   new Uri String Format  file     0  my html html   curDir      You ll have to change the variables and names of course

What worked for me was    lt WebBrowser Source  pack   siteoforigin     StartPage html    gt    from here  I copied StartPage html to the same output directory as the xaml-file and it loaded it from that relative path

quite late but it s the first hit i found from google      Instead of using the current directory or getting the assembly  just use the Application ExecutablePath property      using System IO    string applicationDirectory   Path GetDirectoryName Application ExecutablePath   string myFile   Path Combine applicationDirectory   Sample html    webMain Url   new Uri  file        myFile
