## What it is
ILRepack is an open-source command-line tool that merges multiple .NET assemblies into a single assembly, serving as a replacement for the discontinued ILMerge. It is built on a fork of Mono.Cecil and is available as a NuGet package or a dotnet global tool.

## Use cases
- merge multiple .net dlls into one assembly
- bundle dependencies into a single exe
- open-source alternative to ilmerge
- combine .net assemblies for easier deployment
- repack nuget library into single file
- merge assemblies in a build pipeline

## When to choose
- you need to merge .NET assemblies and want an open-source, customizable tool
- ILMerge is too slow or resource-heavy for your build
- you want ILMerge-compatible syntax with extra options like wildcards
- you prefer installing tools via dotnet tool or NuGet

## When to avoid
- you target non-.NET platforms or languages
- you need merging of obfuscated or signed assemblies with complex scenarios without testing
- you only need simple dependency trimming rather than merging
