Type 'Tamir.SharpSsh.jsch.JSchException' is not marked as serializable.

Question

I have a .NET 3.5 MVC2 web app that runs fine from Visual Studio 2008 but when I publish to a remote site, I get an error in a certain function.

Any idea what I should be looking for here?

Answer 1

Well.. is your exception class marked as serializable?

Answer 2

Aop is right, you have to put [Serializable()] before your class. This tells the compiler this class can be serialized.

[Serializable()]        
public class TestSimpleObject  { ... }
