BinaryFormatter.Deserialize and Smart Clients

[Lambuz]

Hi all,
I'm triying to create a prototype of a smart client that using .NET
Remoting.

I've got an assembly loaded into an HTML page by a tag object
<OBJECT id="myID" height="150" width="300"
classid="http:bin/CPRSWebClient.dll#IBM.Cipros.Refinery.CPRSWebClient"
/>

My assembly is strong named and it is full trusted.

Thi assembly referenced some other assembly also strong named and full
trusted and publish in the same virtual directory of the first one.

The object is correctly loaded inside my HTML page and create correctly
a remote channel and I can instance a remote object.

I've got a problem when I try to invoke a method on this remote object.

I'm sure that the invocation occured correctly server side, but when
the return object arrived client side I've got this exception.

System.Runtime.Serialization.SerializationException:

If I try to instance client side an object like that returned by the
invocation no exception occured.

Any ideas ?

no idea from nobody ?

please help me

I'm sure that the invocation occured correctly server side, but when
the return object arrived client side I've got this exception.

System.Runtime.Serialization.SerializationException:
Cannot find the assembly CprsBaseType, Version=1.0.2460.30737,
Culture=neutral, PublicKeyToken=d046a4512344d447. Server stack trace:

That version - "Version=1.0.2460.30737" - has me worried.

Those last two numbers are [re-]generated every time you rebuild
(re-open?) the project. It's all /too/ easy to wind up with different
versions - and, to the Framework, totally different assemblies - on each
side of the Remoting Divide.

HTH,
