.NET Forum / .NET Framework / CLR / October 2004Assembly.LoadFrom problems called from WindowsService
Hi, I have a Windows Service that processes MSMQ messages and dynamically instantiates 'Message Processor' components according to the message type. I use the Assembly.LoadFrom(<assembly path>) call to load the appropriate assembly from its path. All works fine as far as the assembly itself goes, but I get the FileNotFoundException for any dependencies. I know that LoadFrom should add the path of the dynamically loaded assembly to the list of paths searched for dependencies - but it's not happening for me. If I drop the required assemblies into the Windows Service .exe directory all is fine (even though the dynamic assembly itself is not there). Please help - is there something different about Windows Services that means that this mechanism doesn't work? Thanks, in anticipation. Chris Lewis What is the appdomain's base directory that the window service is running in, and what is the location of the assembly you are loading using LoadFrom? If the assembly is not located in the same directory, or a subdirectory below the appbase, then the runtime cannot automatically resolve the reference. You can subscribe to the appdomain's AssemblyResolve event to manually locate dependencies for the runtime. > Hi, > [quoted text clipped - 18 lines] > > Chris Lewis Thanks a lot David, this worked for me!

Also, that must be specified as a relative path , not an absolute path, and it is relative to the application base directory. > Hello, > [quoted text clipped - 32 lines] >> >> Chris Lewis
