Asp Forum - Problems using Serializable attribute - microsoft.public.dotnet.framework.remoting

Hi!
I read in MSDN that an object could be marshaled by value just be mark it
[Serializable]. When I do this and tries to invoke a method on the object I
get this exception:

An unhandled exception of type 'System.Runtime.Remoting.RemotingException'
occurred in mscorlib.dll
Additional information: Trying to create a proxy to an unbound type.

If I derive the class from MarshalByRefObject everything works fine. I don't
do any changes in my configuration files.

Can some one please tell what's wrong here?

Hi Henke,

From the error you posted its quite difficult to figure out the exact error.
may be you can post the piece of code that is crashing the application.

Anyways here are the list of common remoting errors.

Common Remoting Errors.
1.You Register the channel with a specific port and forget to unregister it
once the use of it is over.
2.Trying to connect to wrong port.
3.By default Remoting Takes the remoting channel name as TCP (if you use TCP
Channel) and you are trying to use the same name for channel again. in your
code.

Hope this helps you.

Thanks
Raghavendra

Hi!
Here's some code...
My Global.asax:
protected void Application_Start(Object sender, EventArgs e)
{
// Configure remoting
BinaryClientFormatterSinkProvider clientProvider = new
BinaryClientFormatterSinkProvider();
BinaryServerFormatterSinkProvider serverProvider = new
BinaryServerFormatterSinkProvider();
serverProvider.TypeFilterLevel = TypeFilterLevel.Full;

System.Collections.IDictionary props = new System.Collections.Hashtable();
props["port"] = 2100;
string channelName = System.Guid.NewGuid().ToString();
props["name"] = channelName;
props["typeFilterLevel"] = TypeFilterLevel.Full;
bllChannel = new TcpChannel(props, clientProvider, serverProvider);
ChannelServices.RegisterChannel(bllChannel);
}

Where I use it:
BaseObject retObject = Activator.GetObject(typeof(CustomerManager),
"tcp://comp00569:2099/CustomerManager");
CustomerList customers = retObject.GetCustomers();

You are hosting your remote object in IIS it seems since your code is in the
Application_Start event. You CANNOT use the TCP channel within IIS. You
can have binary formatting though. Check out this link:

Hosting Remote Objects in Internet Information Services (IIS)
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpguide/html/cpconhostingremoteobjectsininternetinformationservi...

Here's an excerpt:

"you cannot do any of the following:
- Specify an application name when hosting in IIS. The name of the virtual
directory becomes your application name.
- Use the <debug> element in a Web.config file that is used for .NET
remoting configuration.
- Use any channel other than the HttpChannel.
- Use the Web.config file and the <client> element to configure your client
Web application automatically. If you want to use IIS as a remoting client,
you must call RemotingConfiguration.Configure in the Application_Start
method in the Global.asax file"

Thanks,

Sam

Just checking the obvious. Are you deploying your remote object assembly
with your ASP.NET application? Or are you using an interface that your
ASP.NET application has access to? Essentially, are you taking care of
step#5 in this list:

Basic Remoting Task List
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpguide/html/cpconBasicRemotingTa...

Thanks,

Sam

Actually I am deploying my object assembly with my ASP.NET application right
now. But I'm aware that I should deploy interfaces instead. I will do it in
the future.
To answer your question I don't fully take care of step 5.
