Supported build tools

MSBuild

Usage

You just need to install NuGet package to merge all your project dependencies. If you want to customize the process then you can create a file named "ILRepack.targets" in your project folder. You can create it like shown below.

Example "ILRepack.targets"

<!-- ILRepack -->
<?xml version="1.0" encoding="utf-8" ?>
<Project xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
    <Target Name="ILRepacker" AfterTargets="Build" Condition="'$(Configuration)' == 'Release'">

    <ItemGroup>
        <InputAssemblies Include="$(OutputPath)\ExampleAssemblyToMerge1.dll" />
        <InputAssemblies Include="$(OutputPath)\ExampleAssemblyToMerge2.dll" />
        <InputAssemblies Include="$(OutputPath)\ExampleAssemblyToMerge3.dll" />
    </ItemGroup>

    <ItemGroup>
        <!-- Must be a fully qualified name -->
        <DoNotInternalizeAssemblies Include="ExampleAssemblyToMerge3" />
    </ItemGroup>

    <ILRepack
        Parallel="true"
        Internalize="true"
        InternalizeExclude="@(DoNotInternalizeAssemblies)"
        InputAssemblies="@(InputAssemblies)"
        TargetKind="Dll"
        OutputFile="$(OutputPath)\$(AssemblyName).dll"
    />

    </Target>
</Project>
<!-- /ILRepack -->

Configuration

You need to create "ILRepack.Config.props" file in your project folder to configure the behavior of ILRepack.Lib.MSBuild.Task.

<?xml version="1.0" encoding="utf-8" ?>
<Project xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
  <PropertyGroup>
  </PropertyGroup>
</Project>

You can specify following options inside the <PropertyGroup> element to configure the behavior of the ILRepack task.

Specify your custom Targets file path

If you don't want to add "ILRepack.targets" file in your project folder then you can specify your targets file path as shown below.

<ILRepackTargetsFile>$(SolutionDir)ILRepack.targets</ILRepackTargetsFile>

Specify Key File to use for signing

You can specify the path of the SNK file you want to use for signing your assembly as shown below. This configuration option only applies if you are using default targets file provided in NuGet package.

<KeyFile>$(ProjectDir)ILRepack.snk</KeyFile>

Specify whether to clear directory after merging

If you are using default targets file then you may notice that it clears Output directory after merging dependencies. You can turn this functionality off by setting ClearOutputDirectory to False as shown below.

<ClearOutputDirectory>False</ClearOutputDirectory>

Task options

Option	Description
KeyFile	Specifies a KeyFile to sign the output assembly.
KeyContainer	Specifies a KeyContainer to use.
LogFile	Specifies a logfile to output log information.
Union	Merges types with identical names into one.
DebugInfo	Enable/disable symbol file generation.
AttributeFile	Take assembly attributes from the given assembly file.
CopyAttributes	Copy assembly attributes.
AllowMultiple	Allows multiple attributes (if type allows).
TargetKind	Target assembly kind (Exe\|Dll\|WinExe\|SameAsPrimaryAssembly).
TargetPlatformVersion	Target platform (v1, v1.1, v2, v4 supported).
TargetPlatformDirectory	Path of Directory where target platform is located.
XmlDocumentation	Merge assembly xml documentation.
LibraryPath	List of paths to use as "include directories" when attempting to merge assemblies.
Internalize	Set all types but the ones from the first assembly 'internal'.
RenameInternalized	Rename all internalized types (to be used when Internalize is enabled).
InternalizeExclude	If Internalize is set to true, any which match these regular expressions will not be internalized. If internalize is false, then this property is ignored.
OutputFile	Output name for merged assembly.
InputAssemblies	List of assemblies that will be merged.
DelaySign	Set the keyfile, but don't sign the assembly.
AllowDuplicateResources	Allows to duplicate resources in output assembly.
AllowedDuplicateNamespaces	Allows the specified namespaces for being duplicated in to input assemblies. Multiple namespaces are delimited by ",".
ZeroPeKind	Allows assemblies with Zero PeKind (but obviously only IL will get merged).
Parallel	Use as many CPUs as possible to merge the assemblies.
Verbose	Additional debug information during merge that will be outputted to LogFile.
NoRepackRes	Does not add the embedded resource 'ILRepack.List' with all merged assembly names.
Wildcards	Allows (and resolves) file wildcards (e.g. `*`.dll) in input assemblies.
RepackDropAttribute	Name of an attribute (optional). Members in input assemblies marked with this attribute will be dropped during merging.
