ILMerge utility provides integration when developers use different languages Microsoft is offering an upgraded version of its ILMerge utility, which merges multiple .Net assemblies into a single assembly.Functioning with both executables and DLLs, ILMerge provides a capability for .Net assemblies that is analogous to combining multiple Word documents into a single document, according to a Microsoft representative.Someone, for example, may want to deploy a single file to others but half the development team uses Visual Basic and the other uses C#. Neither Visual Studio 2003 nor the upcoming 2005 release of Visual Studio have the inherent capability to combine two assemblies written in different languages. Packaged as a console application, ILMerge takes a set of input assemblies and merges them into a single target assembly, according to Microsoft. Its functionality also is available programmatically.ILMerge is a “power toy for developers,” said analyst Greg DeMichillie, of Directions on Microsoft.“If you’re building a complex .Net application, you will probably have built it as several assemblies, maybe one [for] the user interface and one for the core logic. This tool lets you combine those into one file which can then be copied, installed, [and] deployed,” DeMichillie said. ILMerge functions with Windows 2000, Windows 2003, and Windows XP. It currently will not work with Mono, which is a Unix-based, open source version of the .Net development platform. Software DevelopmentDevelopment Tools
