Fixed version usage

If you want to ship a fixed version of the WebView2 runtime with your application you will need to include it in your project.

Instructions can be found at: https://learn.microsoft.com/en-us/microsoft-edge/webview2/concepts/distribution

The following assume you are using runtime version 95.0.1020.53, you will change this number to whatever version you are using.

You will need to: 1 Include the fixed WebView2 runtime in the package project

\WebView2_WinUI3_Sample\WebView2_WinUI3_Sample (Package)\FixedRuntime\95.0.1020.53\

2 Update the package project wapproj file for the version your using

 < Content Include="FixedRuntime\95.0.1020.53\\**\*.*" > 

3 Uncomment the code in app.xaml.cs to enable the runtime override

public App()
{
    this.InitializeComponent();
    // If you are shipping a fixed version WebView2 SDK with your application you will need
    // to use the following code (update the runtime version to what you are shipping.
    StorageFolder localFolder = Windows.ApplicationModel.Package.Current.InstalledLocation;
    String fixedPath = Path.Combine(localFolder.Path, "FixedRuntime\\95.0.1020.53");
    Debug.WriteLine($"Launch path [{localFolder.Path}]");
    Debug.WriteLine($"FixedRuntime path [{fixedPath}]");
    Environment.SetEnvironmentVariable("WEBVIEW2_BROWSER_EXECUTABLE_FOLDER", fixedPath);
}

4 Update the version information for the appropriate version

 
String fixedPath = Path.Combine(localFolder.Path, "FixedRuntime\\95.0.1020.53");
