Updating existing projects

To update your .NET MAUI project to use 8.0.0-preview.5.8506, you first need to install the .NET 8 Preview 5 SDK and then update the .NET MAUI NuGet packages in your project. You can use Visual Studio or Visual Studio for Mac to manage your NuGet packages or edit your project file manually.

To use Visual Studio or Visual Studio for Mac, right-click on your project and select “Manage NuGet Packages…” then select the “Include prerelease” option and search for Microsoft.Maui. packages. Update all the packages to version 8.0.0-preview.5.8506. To edit your project file manually, open it in a text editor and find the ItemGroup element that contains the PackageReference elements for Microsoft.Maui. packages. Update all the Version attributes to 8.0.0-preview.5.8506.

Your project file should have an ItemGroup that looks something like this:

<ItemGroup>
    <PackageReference Include="Microsoft.Maui.Controls" Version="$(MauiVersion)" />
    <PackageReference Include="Microsoft.Maui.Controls.Compatibility" Version="$(MauiVersion)" />
    <PackageReference Include="Microsoft.Extensions.Logging.Debug" Version="8.0.0-preview.5.23280.8" />
</ItemGroup>

Now you can build and run your project using Visual Studio or Visual Studio for Mac or use the dotnet build command with the -t:Run target:

dotnet build -t:Run -f net8-android MyMauiApp.csproj

This will build and launch your app on an Android emulator or device.
