Cant unload assembly

Hi,

i tried to load an assembly to an appdomain. The data output is
correctly but the assembly is still in use after unloading the appdomain...

What am I doing wrong?
Please help!
My current code:

-------------------------------------------------------------------------

' Assembly
Dim AssemblyToLoad As [Assembly]
Dim ClassLibraryMod ule As [Module]
Dim FormType As Type
Dim AssemblyForm As Form
Dim PublicField As FieldInfo

' Application Domain
Dim AppdomainSetup As New AppDomainSetup
Dim baseEvidence As Evidence = AppDomain.Curre ntDomain.Eviden ce
Dim evidence As New Evidence(baseEv idence)
Dim newDomain As AppDomain

' Files
Dim Directory As Directory
Dim ModuleName As String
Dim File As File
ModuleName = "Testmodule.dll "

' Load assembly from file
AppdomainSetup. ApplicationBase = Application.Sta rtupPath

AssemblyToLoad = [Assembly].LoadFrom(Modul eName, evidence)

newDomain = AppDomain.Creat eDomain("Module ", evidence, AppdomainSetup)

' Load the class library
ClassLibraryMod ule = AssemblyToLoad. GetModule(Modul eName)

' define start form
ModuleName = Replace(ModuleN ame, ".dll", "", , , CompareMethod.T ext)
FormType = ClassLibraryMod ule.GetType(Mod uleName & ".Frm_Main" )

PublicField = FormType.GetFie ld("Build")
msgbox("Current build: " & PublicField.Get Value(PublicFie ld))

newDomain.Unloa d(newDomain)

You have to wrap all accesses to the other assembly within a remoted object
running in the context of the second appdomain.

I am having trouble gettting an assembly loaded with Assembly.LoadFrom. I can get the assembly call the method I need to call. Now I want to unload the assembly. I need to do this so that the user can (thru my app) create a new version of the assembly. The app will call a predetermined method (sort of an add-in) and then exit.

Hi everybody. I load an assembly into another AppDomain, not a default one. As there is no way to unload the assembly, I need to unload the domain. This is where the app hangs. The problem is this assembly has references to one dll, currently not performing any work. I tried this: 1. Setting the assembly to null, 2. Implementing a ClassFactory and returning an interface of the object,

Hello, I have read numerous post stating that the only way to unload an assembly (DLL in my case) is to create a separate AppDomain, load the assembly, then unload it by calling AppDomain.Unload. When trying to delete the DLL file I get an exception that access is denied. When trying to copy over the DLL file, I get an exception that it is being used by another process.

Morning all, Right, I've read untold articles now, listening to people bitch about there being no Unload method for Assembly. Plenty of people do counter that this is possible by loading the Assemblies into a seperate AppDomain and closing it when finish, which would suit me fine. However, I have been able to find an example.

Hi there. There are various snippets on forums regarding issues with AppDomain.Unload and how it just doesnt work. Fortunately, I got it working with the base case, after much fiddling. Consider this 5 line program: AppDomain domain = AppDomain.CreateDomain("MyDomain"); domain.CreateInstance("TempDLL", "TempDLL.Class1"); MessageBox.Show("try deleting file now"); //cant delete file AppDomain.Unload(domain);
