I ve seen several suggestions  that you can add hyperlink to WPF application through Hyperlink control   Here s how I m trying to use it in my code     lt Window         xmlns  http   schemas microsoft com winfx 2006 xaml presentation          xmlns x  http   schemas microsoft com winfx 2006 xaml          xmlns d  http   schemas microsoft com expression blend 2008           xmlns mc  http   schemas openxmlformats org markup-compatibility 2006           mc Ignorable  d           x Class  BookmarkWizV2 InfoPanels Windows UrlProperties          Title  UrlProperties  Height  754  Width  576  gt       lt Grid gt           lt Grid RowDefinitions gt               lt RowDefinition gt  lt  RowDefinition gt               lt RowDefinition Height  40   gt           lt  Grid RowDefinitions gt           lt Grid gt               lt ScrollViewer ScrollViewer VerticalScrollBarVisibility  Auto  Grid RowSpan  2  gt                   lt StackPanel  gt                       lt DockPanel LastChildFill  True  Margin  0 5  gt                           lt TextBlock Text  Url   Margin  5                               DockPanel Dock  Left  VerticalAlignment  Center   gt                           lt TextBox Width  Auto  gt                               lt Hyperlink NavigateUri  http   www google co in  gt                                      Click here                              lt  Hyperlink gt                              lt  TextBox gt                                             lt  DockPanel  gt                   lt  StackPanel gt               lt  ScrollViewer gt                   lt  Grid gt           lt StackPanel HorizontalAlignment  Right  Orientation  Horizontal  Margin  0 7 2 7  Grid Row  1   gt               lt Button Margin  0 0 10 0  gt                   lt TextBlock Text  Accept  Margin  15 3    gt               lt  Button gt               lt Button Margin  0 0 10 0  gt                   lt TextBlock Text  Cancel  Margin  15 3    gt               lt  Button gt           lt  StackPanel gt       lt  Grid gt   lt  Window gt    I m getting following error      Property  Text  does not support values of type  Hyperlink       What am I doing wrong

I used the answer in this question and I got an issue with it.

It return exception: {"The system cannot find the file specified."}

After a bit of investigation. It turns out that if your WPF application is CORE, you need to change UseShellExecute to true.

This is mentioned in Microsoft docs:

true if the shell should be used when starting the process; false if the process should be created directly from the executable file. The default is true on .NET Framework apps and false on .NET Core apps.

So to make this work you need to added UseShellExecute and set it to true:

Process.Start(new ProcessStartInfo(e.Uri.AbsoluteUri){ UseShellExecute = true });

Hyperlink is not a control  it is a flow content element  you can only use it in controls which support flow content  like a TextBlock  TextBoxes only have plain text

If you want to localize string later  then those answers aren t enough  I would suggest something like    lt TextBlock gt       lt Hyperlink NavigateUri  http   labsii com   gt          lt Hyperlink Inlines gt               lt Run Text  Click here   gt          lt  Hyperlink Inlines gt      lt  Hyperlink gt   lt  TextBlock gt

One of the most beautiful ways in my opinion  since it is now commonly available  is using behaviours   It requires     nuget dependency  Microsoft Xaml Behaviors Wpf if you already have behaviours built in you might have to follow this guide on Microsofts blog     xaml code   xmlns Interactions  http   schemas microsoft com xaml behaviors    AND    lt Hyperlink NavigateUri   Binding Path Link   gt       lt Interactions Interaction Behaviors gt           lt behaviours HyperlinkOpenBehaviour ConfirmNavigation  True   gt       lt  Interactions Interaction Behaviors gt       lt Hyperlink Inlines gt           lt Run Text   Binding Path Link    gt       lt  Hyperlink Inlines gt   lt  Hyperlink gt    behaviour code   using System Windows  using System Windows Documents  using System Windows Navigation  using Microsoft Xaml Behaviors   namespace YourNameSpace       public class HyperlinkOpenBehaviour   Behavior lt Hyperlink gt                public static readonly DependencyProperty ConfirmNavigationProperty   DependencyProperty Register              nameof ConfirmNavigation   typeof bool   typeof HyperlinkOpenBehaviour   new PropertyMetadata default bool              public bool ConfirmNavigation                       get   return  bool  GetValue ConfirmNavigationProperty                 set   SetValue ConfirmNavigationProperty  value                             lt inheritdoc   gt          protected override void OnAttached                         this AssociatedObject RequestNavigate    NavigationRequested              this AssociatedObject Unloaded    AssociatedObjectOnUnloaded              base OnAttached                       private void AssociatedObjectOnUnloaded object sender  RoutedEventArgs e                        this AssociatedObject Unloaded -  AssociatedObjectOnUnloaded              this AssociatedObject RequestNavigate -  NavigationRequested                     private void NavigationRequested object sender  RequestNavigateEventArgs e                        if   ConfirmNavigation    MessageBox Show  Are you sure     Question   MessageBoxButton YesNo  MessageBoxImage Question     MessageBoxResult Yes                                OpenUrl                               e Handled   true                     private void OpenUrl                         Process Start new ProcessStartInfo AssociatedObject NavigateUri AbsoluteUri                MessageBox Show   Opening  AssociatedObject NavigateUri                             lt inheritdoc   gt          protected override void OnDetaching                         this AssociatedObject RequestNavigate -  NavigationRequested              base OnDetaching

Hope this help someone as well   using System Diagnostics  using System Windows Documents   namespace Helpers Controls       public class HyperlinkEx   Hyperlink               protected override void OnClick                         base OnClick                 Process p   new Process                                 StartInfo   new ProcessStartInfo                                         FileName   this NavigateUri AbsoluteUri                                              p Start

I liked Arthur s idea of a reusable handler  but I think there s a simpler way to do it   private void Hyperlink RequestNavigate object sender  RequestNavigateEventArgs e        if  sender GetType      typeof  Hyperlink           return      string link     Hyperlink  sender  NavigateUri ToString        Process Start link       Obviously there could be security risks with starting any kind of process  so be carefull

In addition to Fuji s response  we can make the handler reusable turning it into an attached property  public static class HyperlinkExtensions       public static bool GetIsExternal DependencyObject obj                return  bool obj GetValue IsExternalProperty              public static void SetIsExternal DependencyObject obj  bool value                obj SetValue IsExternalProperty  value             public static readonly DependencyProperty IsExternalProperty           DependencyProperty RegisterAttached  quot IsExternal quot   typeof bool   typeof HyperlinkExtensions   new UIPropertyMetadata false  OnIsExternalChanged         private static void OnIsExternalChanged object sender  DependencyPropertyChangedEventArgs args                var hyperlink   sender as Hyperlink           if   bool args NewValue              hyperlink RequestNavigate    Hyperlink RequestNavigate          else             hyperlink RequestNavigate -  Hyperlink RequestNavigate             private static void Hyperlink RequestNavigate object sender  System Windows Navigation RequestNavigateEventArgs e                Process Start new ProcessStartInfo e Uri AbsoluteUri            e Handled   true           And use it like this   lt TextBlock gt       lt Hyperlink NavigateUri  quot https   stackoverflow com quot                 custom HyperlinkExtensions IsExternal  quot true quot  gt          Click here      lt  Hyperlink gt   lt  TextBlock gt

Note too that Hyperlink does not have to be used for navigation  You can connect it to a command   For example    lt TextBlock gt     lt Hyperlink Command   Binding ClearCommand   gt Clear lt  Hyperlink gt   lt  TextBlock gt

IMHO the simplest way is to use new control inherited from Hyperlink        lt summary gt      Opens  lt see cref  Hyperlink NavigateUri   gt  in a default system browser      lt  summary gt  public class ExternalBrowserHyperlink   Hyperlink       public ExternalBrowserHyperlink                 RequestNavigate    OnRequestNavigate             private void OnRequestNavigate object sender  RequestNavigateEventArgs e                Process Start new ProcessStartInfo e Uri AbsoluteUri            e Handled   true

If you want your application to open the link in a web browser you need to add a HyperLink with the RequestNavigate event set to a function that programmatically opens a web-browser with the address as a parameter   lt TextBlock gt                  lt Hyperlink NavigateUri  quot http   www google com quot  RequestNavigate  quot Hyperlink RequestNavigate quot  gt          Click here      lt  Hyperlink gt   lt  TextBlock gt   In the code-behind you would need to add something similar to this to handle the RequestNavigate event  private void Hyperlink RequestNavigate object sender  RequestNavigateEventArgs e           for  NET Core you need to add UseShellExecute   true        see https   docs microsoft com dotnet api system diagnostics processstartinfo useshellexecute property-value     Process Start new ProcessStartInfo e Uri AbsoluteUri        e Handled   true     In addition you will also need the following imports  using System Diagnostics  using System Windows Navigation   It will look like this in your application
