versioning and BinaryFormatter

Hi all,

i want to save my application to a file with a BinaryFormatter . I
have some questions how the BinaryFormatter will work when the I
update my application. How can I make sure that I can still read older
saved files.

I looked for a tutorial but can't seem to find one. Someone has
experience with BinaryFormatter and versioning?

You need to ensure that you can reload the old objects into the newer
versions. This is quite complex with Binary serialization. You need to lookup
serialization surrogates. check out
System.Runtime. Serialization.S urrogateSelecto r class and associated

Let me know if you still need help as I have old code samples somewhere
using them.

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?

Hi All, I have an annoying trouble with binary serialization. I have a windows forms application which works like a server and keeps sending data to its clients. The data is serialized before being sent using BinaryFormatter and a serializable object. When using a windows forms application as a client, everything works just fine and deserialized data can be received intact. When the client application is is embedded in Internet Explorer (I...

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.

Hi all, I have seen a number of posts re: the BinaryFormatter version incompatibility but nothing on how to recover from it. In my case, I want the exception to trigger an alternate behaviour and continue process the stream. My app reads and writes configuration settings to a binary file upon starting and shutdown. The settings are stored in various objects that are serialized and deserialized using a BinaryFormatter. When reading...

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. 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,...
