// Load the assembly in a new AppDomain mainly so that we are able to unload it, which is necessary when we want to delete all temporary files including this assembly.
AppDomainSetup setupInformation = AppDomain.CurrentDomain.SetupInformation;
AppDomain newAppDomain = AppDomain.CreateDomain("newAppDomain", AppDomain.CurrentDomain.Evidence, setupInformation);
//Create an instance of the inspector class in the new domain:
//System.Runtime.Remoting.ObjectHandle obj = newAppDomain.CreateInstance(typeof(AssemblyInspectorOnOtherDomain).Assembly.FullName, typeof(AssemblyInspectorOnOtherDomain).FullName);
string pathOfThisVeryAssembly = PathsHelper.GetPathOfThisVeryAssembly();
System.Runtime.Remoting.ObjectHandle obj = newAppDomain.CreateInstanceFrom(pathOfThisVeryAssembly, typeof(AssemblyInspectorOnOtherDomain).FullName);
IAssemblyInspectorOnOtherDomain inspector = (IAssemblyInspectorOnOtherDomain)obj.Unwrap(); // As the object we are creating is from another appdomain hence we will get that object in wrapped format and hence in next step we have unwrappped it
// Call LoadAssembly method so that the assembly will be loaded into the new appdomain amd the object will also remain in new appdomain only:
inspector.LoadAssembly(pathOfAssemblyThatContainsEntryPoint);
// Call the method that finds the type that inherits from Application:
applicationClassFullName = inspector.FindApplicationClassFullName();
// Get the assembly name and full name too:
assemblyName = inspector.GetAssemblyName();
assemblyFullName = inspector.GetAssemblyFullName();
// Unload the assembly (so that we can later delete it if necessary):
AppDomain.Unload(newAppDomain);
GC.Collect(); // Collects all unused memory
GC.WaitForPendingFinalizers(); // Waits until GC has finished its work
GC.Collect();
