Getting started
Step 1: Prepare your WPF project
Make sure that your project has been updated/ported to net7.0-windows
and uses the new SDK csproj format.
For more information see the Microsoft How to upgrade a WPF desktop app to .NET 7 guide.
Confirm that your project runs acceptably on .NET 7 with WPF.
This step is vital. XPF will not work with the old/legacy .csproj
format or versions of .NET less than 6.0. You must first convert your project, and ensure that WPF works with modern .NET version before attempting to use XPF.
If you are running on Linux, see the linux guide before you install .NET.
See our porting tips for a more detailed run-through of this step.
This document specifies .NET 7.0, but net6.0
should also work
Step 2: Add a NuGet.config
Create a NuGet.config
file at the root of your solution, or modify an existing one to contain the following:
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<packageSources>
<clear />
<add key="api.nuget.org" value="https://api.nuget.org/v3/index.json" />
<add key="xpf" value="https://xpf-nuget-feed.avaloniaui.net/v3/index.json" />
<add key="avalonia-nightly" value="https://nuget-feed-all.avaloniaui.net/v3/index.json" />
</packageSources>
<packageSourceCredentials>
<xpf>
<add key="Username" value="license" />
<add key="ClearTextPassword" value="<YOUR_LICENSE_KEY>" />
</xpf>
</packageSourceCredentials>
</configuration>
Step 3: Use the XPF SDK
In the executable WPF project, change the SDK to use the XPF SDK in the .csproj
. The first line:
<Project Sdk="Microsoft.NET.Sdk">
should be changed to:
<Project Sdk="Xpf.Sdk/1.1.0">
XPF is in active development and the CI build version changes frequently. The version given here was the latest version at the time of writing, but it is likely that newer versions are available. You can find the latest CI build version at https://xpf-nuget-feed.avaloniaui.net/packages/xpf.sdk. See nightly builds for more information.
If you have multiple projects which will need to use the same XPF SDK vesion, you can specify this version in global.json
Step 4: Add your Licence Key
In your executable's .csproj
, add:
<ItemGroup>
<RuntimeHostConfigurationOption Include="AvaloniaUI.Xpf.LicenseKey" Value="<YOUR_LICENSE_KEY>" />
</ItemGroup>
Note, that if you have a production license, the AssemblyName of the project has to match your license key
Step 5: Clean your solution
Changing the project SDK requires a clean of existing build artifacts:
- Run
dotnet clean
from the command line; or - Use
Build -> Clean Solution
from your IDE; or - Delete your
obj
/bin
directories manually
Step 6: Run the project
You should be able to run your project from your preferred IDE with Avalonia XPF or use dotnet run
.
If running on Linux see the Linux page for information on how to install .NET and required dependencies.
Additional Projects
If you have non-executable projects that are using WPF APIs and need to build those on Linux or macOS, you can either change the SDK as described above, or if you're targeting net7.0-windows
add:
<PropertyGroup>
<EnableWindowsTargeting>true</EnableWindowsTargeting>
</PropertyGroup>
to the corresponding project file.
Alternatively create a Directory.Build.props
file at the root of your solution with the following contents:
<Project>
<PropertyGroup>
<EnableWindowsTargeting>true</EnableWindowsTargeting>
</PropertyGroup>
</Project>
Target Framework
Ideally all projects which reference XPF should be using the net6.0-windows
or net7.0-windows
TFM. You can use the net6.0
or net7.0
TFM but in this case you cannot use <EnableWindowsTargeting>
and instead must use the XPF SDK.
