Compile Xaml into Baml?

Question

How can I convert a xaml to baml?

thanks

Answer 1

There is a Reflector plug-in that loads assemblies containing BAML resources (e.g. localized resource assemblies) and shows the corresponding XAML: BamlViewer

When you compile a WPF application in Visual Studio, all your XAML files are converted into BAML, and that BAML is then embedded as a resource into the final DLL or EXE assembly.

You can compile the XAML by creating an MSBuild project file that references it. This is what happens in Visual Studio "under the covers" when you do a compile on your project (it creates a temporary .proj file and builds it).

A fairly minimal project file (xamlcompile.csproj) is something like this:

<?xml version="1.0" encoding="utf-8"?>
<Project ToolsVersion="3.5" DefaultTargets="Build" xmlns="http://schemas.microsoft.com/developer/msbuild/2003"&gt;
  <PropertyGroup>
    <ProductVersion>9.0.30729</ProductVersion>
    <SchemaVersion>2.0</SchemaVersion>
    <OutputType>library</OutputType>
    <TargetFrameworkVersion>v3.5</TargetFrameworkVersion>
    <ProjectGuid>{6B8967FF-37B7-43E8-B866-FFD6F13FFC0A}</ProjectGuid>
  </PropertyGroup>
  <ItemGroup>
    <Reference Include="System" />
    <Reference Include="System.Core">
      <RequiredTargetFramework>3.5</RequiredTargetFramework>
    </Reference>
    <Reference Include="System.Xml.Linq">
      <RequiredTargetFramework>3.5</RequiredTargetFramework>
    </Reference>
    <Reference Include="System.Data.DataSetExtensions">
      <RequiredTargetFramework>3.5</RequiredTargetFramework>
    </Reference>
    <Reference Include="System.Data" />
    <Reference Include="System.Xml" />
    <Reference Include="WindowsBase" />
    <Reference Include="PresentationCore" />
    <Reference Include="PresentationFramework" />
    <Reference Include="PresentationFramework.Classic" />
  </ItemGroup>
  <ItemGroup>
    <Page Include="Themes\Generic.xaml">
      <Generator>MSBuild:Compile</Generator>
      <SubType>Designer</SubType>
    </Page>
  </ItemGroup>
  <Import Project="$(MSBuildToolsPath)\Microsoft.CSharp.targets" />
</Project>

And you can then generate the BAML file by running the command:

MSBuild /t:ResolveReferences;MarkupCompilePass1;MarkupCompilePass2 xamlcompile.csproj

This will create a baml file under obj\Debug, in the example above it will be obj\Debug\Themes\Generic.baml.

Hope that helps.
