AppDomain.Load assembly file not found exception ?

AppDomain.Load assembly file not found exception ?

• JeffRozar

  Hello

  I have exactly the same problem .

  Seems to be when loading seperate Application Domain when running an designer (in VS ) something works a litle different.

  And yes for me too Assembly Resolve of secondary application domain does not trigerred.

  Did you tried the shadow copy files . I believe this time assembly must be unloaded when secondary application domains unloads...

  Mybe this time works .....

  If its works notify me too please

  Good to hear someone actually has the same problem! I'm trying to figure it out through all kinds of ways, but no progress yet. Could you please report back any progress on your side as well

  Thanks!!

  It probably gets fired in the wrong AppDomain. Small chance: register it for AppDomain.CurrentDomain...
  
  It is clearly probing the wrong folder for the assembly. Do you have the hosting process enabled (Project + properties, Debug tab) What folder is "fullPath" pointing to

  Hi,
  
  I also have the same problem. Could you be a bit more specific about the solution you found Perhaps throw in some code too Thanx a lot in advance...

  Heya.. I figured it out... It's not easy though... you have to use .NET Remoting on this. MarshalByRefObject and use CreateInstanceAndUnwrap on your appDomain. You can pass data from the MarshalByRefObject implementer to your current appdomain. But this cannot be type information, just strings/ints etc.. (by value! not by reference) .. and you can also pass serializable objects you created yourself or simple arrays.

  Thanks for your reply. I've already tried this, but the ad_AssemblyResolve never gets called (dropped a breakpoint in there). Any reason

  Code:

  public void myDynamicLoad()

  {

  AppDomainSetup ads = new AppDomainSetup();

  String fullPath = GetAssemblyFileName();

  ads.ApplicationBase = Path.GetDirectoryName( fullPath );

  ads.PrivateBinPath = Path.GetDirectoryName( fullPath );

  AppDomain ad = AppDomain.CreateDomain( "myName", null, ads );

  ad.AssemblyResolve += new ResolveEventHandler( ad_AssemblyResolve );

  try

  {

  ad.Load( AssemblyName.GetAssemblyName( fullPath ) );

  }

  catch( Exception e )

  {

  MessageBox.Show( e.Message );

  }

  }

   

   

   

  static Assembly ad_AssemblyResolve( object sender, ResolveEventArgs args )

  {

  return Assembly.LoadFile( GetAssemblyFileName() );

  }

  Try using the AppDomain.AssemblyResolve event to help it find the assembly.

  Thanks again, really appreciate you putting effort in this!

  "Enable the visual studio hosting process" is greyed out. Probably because my external program to start (and load) .dll is:

  C:\Program Files\Microsoft Visual Studio 8\Common7\IDE\\devenv.exe

  (with command line arguments: /rootsuffix Exp /DesignTimeRun )

  The fullPath is most certainly pointing to the right directory. It works with Assembly.LoadFile( fullPath ); just not in the seperate appDomain.

  ---------

  ah, if I change the appDomain to CurrentDomain (this line of code):

  AppDomain.CurrentDomain.AssemblyResolve += new ResolveEventHandler( ad_AssemblyResolve );

  Then the assembly gets loaded.

  HOWever, I'm not able to remove the assembly at runtime when I unload the domain, for its handle is still open ( ) probably because it is loaded in the CurrentDomain as well as in my own appDomain

  Any thoughts on that as well

  Greets,
