How Can I Merge ServiceStack DLLs into a Single EXE for Deployment?

Combine multiple assemblies into one file for use by ServiceStack

When using the ServiceStack service from an EXE project, you may encounter a missing ServiceStack DLL during deployment. This is because the EXE project does not automatically bundle dependent DLLs.

To resolve this issue, there are a few ways you can merge the necessary DLLs into your EXE:

Method 1: ILMerge

ILMerge is a free tool that allows you to merge multiple .NET assemblies into a single file.

• Install ILMerge.
• Create a batch script or use the command prompt to merge the DLL: ILMerge /target:exe /out:MergedAssemblies.exe YourExe.exe ServiceStack.dll Azure.dll
• Replace YourExe.exe with the name of your EXE project.

Method 2: SmartAssembly

SmartAssembly is a commercial tool that provides advanced functionality for embedding and merging DLLs.

• Install SmartAssembly.
• Load your EXE project into SmartAssembly.
• Configure the tool to embed or merge the necessary ServiceStack and Azure DLLs.
• Build the project to create an updated EXE containing the merged assembly.

Method 3: Customize AssemblyResolve handler

This method involves modifying your source code to handle assembly resolution at runtime.

• Mark the required dependencies as "Embedded Resources" in your project properties.
• Create an AssemblyResolve handler in your code that reads the DLL from the embedded resource and returns it to the .NET runtime.
• Make sure your EXE project is compiled with the "Embed Interop Types" option enabled.
