hello,

i have a weird problem. i would like to delete an assembly(plugin.dll on harddisk) which is already loaded, but the assembly is locked by the operating system (vista), even if i have unloaded it.

f.e.

AppDomainSetup setup = new AppDomainSetup();
setup.ShadowCopyFiles = "true";
AppDomain appDomain = AppDomain.CreateDomain(assemblyName + "_AppDomain", AppDomain.CurrentDomain.Evidence, setup);
IPlugin plugin = (IPlugin)appDomain.CreateInstanceFromAndUnwrap(assemblyName,                        "Plugin.MyPlugins");

I also need the assemblyinfos, because I don't know which classes in the pluginassembly implements the IPlugin Interface. It should be possible to have more than one Plugin in one Pluginassembly.

Assembly assembly = appDomain.Load(assemblyName);
if (assembly != null) {
   Type[] assemblyTypes = assembly.GetTypes();
   foreach (Type assemblyTyp in assemblyTypes) {
      if (typeof(IPlugin).IsAssignableFrom(assemblyTyp)) {
         IPlugin plugin = (IPlugin)Activator.CreateInstance(assemblyTyp);
         plugin.AssemblyName = assemblyNameWithEx;
         plugin.Host = this;
      }
   }
}
AppDomain.Unload(appDomain);

How is it possible to get the assemblyinfos from the appDomain without locking the assembly?

best regards
