Foolowing is the overview from above URL:
The first assembly in the list of input assemblies is the primary assembly. When the primary assembly is an executable, then the target assembly is created as an executable with the same entry point as the primary assembly. Also, if the primary assembly has a strong name, and a .snk file is provided, then the target assembly is re-signed with the specified key so that it also has a strong name.

ILMerge is packaged as a console application. But all of its functionality is also available programmatically. Note that Visual Studio 2005 does allow one to add an executable as a reference, so you can write a C# client that uses ILMerge as a library.

ILMerge runs in the v2.0 .NET Runtime, but it is also able to merge v1 or v1.1 assemblies. However it can merge PDB files only for v2 assemblies.
