Two persons independently said me that the primary problem somehow regards to STA. If you remove
[STAThread]
static void Main(string[] args)
attribute, there will be no problems.
Also this problem sometimes occurs when you work with SQL server in STA.

The call to GC.Collect after initializing Remoting have solved this problem for me.
[STAThread]
public static void Main()
{
System.Runtime.Remoting.RemotingConfiguration.Configure (
System.Reflection.Assembly.GetExecutingAssembly().Location + ".config" );
GC.Collect();
GC.WaitForPendingFinalizers();

I have rewritten your test programs in C++, using the STA model. I do not see the memory leak - all objects are finalised. I am using the framework 1.1 service pack 1. Do you know if the service pack fixes the problem or is there some difference between C++ and C# (I only have the C++ IDE)?

Sorry for a long pause, didn't notice the message.
Frankly speaking, I have no idea why it works. Probably, there is some difference between implementations. The core reason is that Garbage Collector works only in the main STA thread (in order to execute objects' destructors in the main thread). If you make an invocation that goes to WinAPI and doesn't return, all objects created in other threads cannot be collected.

I dont see difference when I drive that sample with line RemotingConfiguration.Configure("Server.exe.config"); and without it.
In both cases destructor of the aClass never called until server process is goining down.

I did not see any difference too, the "Called!" string is only showed if I change the [STAThread] to [MTAThread]

I try to run MS 101 VB.NET sample code using tcp mode. I got no memory leak at all in the server after creating million of objects containing large memory usage (1mega bytes) created inside the class. The memory usage is go up and down as I expected that GC picks up unused objects and delete them.
I wonder if the statement from Dmitry Belikov only true if you create remoting lirary with Genuinechannels.
Does any got a problem in creating Remoting library using VB.NET 1.1 in VS 2003, and using Remote configuration file to load your setting.
Thanks

Any one knows whether this memory leak problem still exists in .Net 2.0?
