I am attempting to load a dll into a console app and then unload it and delete the file completely. The problem I am having is that the act of loading the dll in its own AppDomain creates a reference in the Parent AppDomain thus not allowing me to destroy the dll file unless I totally shut down the program. Any thoughts on making this code work?

string fileLocation = @"C:\Collector.dll";
AppDomain domain = AppDomain.CreateDomain(fileLocation);
domain.Load(@"Services.Collector");
AppDomain.Unload(domain);

BTW I have also tried this code with no luck either

string fileLocation = @"C:\Collector.dll";
byte[] assemblyFileBuffer = File.ReadAllBytes(fileLocation);

AppDomainSetup domainSetup = new AppDomainSetup();
domainSetup.ApplicationBase = Environment.CurrentDirectory;
domainSetup.ShadowCopyFiles = "true";
domainSetup.CachePath = Environment.CurrentDirectory;
AppDomain tempAppDomain = AppDomain.CreateDomain("Services.Collector", AppDomain.CurrentDomain.Evidence, domainSetup);

//Load up the temp assembly and do stuff 
Assembly projectAssembly = tempAppDomain.Load(assemblyFileBuffer);

//Then I'm trying to clean up 
AppDomain.Unload(tempAppDomain);
tempAppDomain = null;
File.Delete(fileLocation);
