BinaryFormatter .Deserialize and Smart Clients

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:b in/CPRSWebClient.d ll#IBM.Cipros.R efinery.CPRSWeb Client"
/>

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.S erializationExc eption:
Cannot find the assembly CprsBaseType, Version=1.0.246 0.30737,

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

Any ideas ?

That version - "Version=1.0.24 60.30737" - 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.

Hi everybody, In my application, I'm planning to use BinaryFormatter to serialize a potentially huge object to file (and, of course, deserialize back to memory later). My question is if there is any hard limit on the size of this object? Is it only limited by the amount of memory or hard-disk space in the server?

I'm getting a very weird exception and hoping someone may be able to help. I have an Office Add-In that lives in a .dll (for email reference ai.dll) ai.dll makes calls into the core part of the application implementation in another .dll (let's call that app.dll). app.dll makes a function call into another dll (let's call that one dep.dll). dep.dll has some code in it where it deserializes a memorystream using a binaryformatter.

In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
