XamlToCSharpGenerator.Generator.WPF 0.1.3

XAML Source Generator for WPF (WXSG) Toolset

WXSG replaces WPF's classic XAML/BAML codegen path with Roslyn source generation and emits typed InitializeComponent() code directly in C#.

This toolset is independent and unaffiliated with Microsoft.

This repo's reference usage is: vscode-wpf/sample/net6.0-csharp-expressions.

What You Get

• Source-generated InitializeComponent() for WPF XAML.
• Typed x:Name fields in generated partial classes.
• C# expression support in XAML via {cs: ...}. Preview in .NET MAUI 11.
• Simpler XAML support (implicit standard namespaces for WXSG parsing). Preview in .NET MAUI 10.

Quick Start (Project Consumption)

Published package page: https://www.nuget.org/packages/XamlToCSharpGenerator.Generator.WPF

1. Add WXSG package reference:

<ItemGroup>
  <PackageReference Include="XamlToCSharpGenerator.Generator.WPF" Version="0.1.0" PrivateAssets="all" />
</ItemGroup>

2. Enable WXSG in your .csproj:

<PropertyGroup>
  <UseWPF>true</UseWPF>
  <WpfXsgEnabled>true</WpfXsgEnabled>
</PropertyGroup>

That is enough for normal package usage because the package ships buildTransitive props/targets.

Local Package Development Flow (Optional, Advanced)

When developing WXSG from source (as in vscode-wpf), use a local package feed:

<PropertyGroup>
  <RestoreSources>$(MSBuildProjectDirectory)\..\..\artifacts\local-packages;$(RestoreSources)</RestoreSources>
</PropertyGroup>

Pack locally:

dotnet pack src\XamlToCSharpGenerator.Generator.WPF\XamlToCSharpGenerator.Generator.WPF.csproj -c Debug -o artifacts\local-packages

Then restore/build:

dotnet restore sample\net6.0-csharp-expressions\sample.csproj --no-cache
dotnet build sample\net6.0-csharp-expressions\sample.csproj

XAML Example

From the sample:

<Window xmlns:local="clr-namespace:sample"
        x:Class="sample.MainWindow"
        Title="{cs: string.Concat(&quot;WXSG — &quot;, &quot;C# Expressions + Simpler XAML&quot;)}"
        Width="{cs: 520}"
        Height="{cs: 420}">

  <Window.Resources>
    <local:GreetingViewModel x:Key="Vm" />
  </Window.Resources>

  <Grid DataContext="{StaticResource Vm}" Margin="20">
    <TextBlock x:Name="GreetingLabel" Text="{Binding Greeting}" />
  </Grid>
</Window>

Notes

• xmlns:local="clr-namespace:YourNamespace" is still needed when referencing your own CLR types (for example view models in Window.Resources), unless you declare an equivalent global prefix.
• Simpler XAML here means you can omit repeated standard header declarations in WXSG input while still keeping normal WPF semantics.
