Using and distributing a fixed version of the Windows Webview2 Runtime with MAUI

This sample shows how to use and distribute a fixed Version Windows WebView2 Runtime with your MAUI App. Follow these instructions to use the sample.

1. Download the Fixed version installer packages from here: https://developer.microsoft.com/en-us/microsoft-edge/webview2/#download-section

2. Extract the packages into a Runtimex86, Runtimex64 and RuntimeARM64 folders in your solution folder. This will keep the files outside your project and keep your Solution Explorer clean. First use the expand command to expand the .cab file and then rename the folder as appropriate.

   expand {path to the package} -F:* {path to the destination folder}   
   

   Example, from a PowerShell terminal:

   expand "C:\Downloads\Microsoft.WebView2.FixedVersionRuntime.114.0.1823.79.x64.cab" -F:* C:\src\MySolution\
   rename-item "C:\src\MySolution\Microsoft.WebView2.FixedVersionRuntime.114.0.1823.79.x64" "C:\src\MySolution\Runtimex64"
   

3. Add the following code to CreateMauiApp() in MauiProgram.cs:

   #if WINDOWS
           string relativePath = @"\Runtime";
           string basePath = AppContext.BaseDirectory;
           string wvrPath = Path.Combine(basePath, relativePath);
           Environment.SetEnvironmentVariable("WEBVIEW2_BROWSER_EXECUTABLE_FOLDER", wvrPath);
   #endif
   
   

4. After the existing <MauiAsset> element, add the following to your .csproj file:

   <MauiAsset Include="..\Runtimex86\**" 
              LogicalName="Runtime\%(RecursiveDir)%(Filename)%(Extension)" 
              Condition="$([MSBuild]::GetTargetPlatformIdentifier('$(TargetFramework)')) == 'windows' And ('$(PlatformTarget)' == 'x86')"/>
   <MauiAsset Include="..\Runtimex64\**" 
              LogicalName="Runtime\%(RecursiveDir)%(Filename)%(Extension)" 
              Condition="$([MSBuild]::GetTargetPlatformIdentifier('$(TargetFramework)')) == 'windows' And ('$(PlatformTarget)' == 'x64')"/>
   <MauiAsset Include="..\RuntimeARM64\**" 
              LogicalName="Runtime\%(RecursiveDir)%(Filename)%(Extension)" 
              Condition="$([MSBuild]::GetTargetPlatformIdentifier('$(TargetFramework)')) == 'windows' And ('$(PlatformTarget)' == 'ARM64')"/>
