This works fine:
Func<string, string> func1 = s => s + "func";
ViewState["function"] = func1;
However, this does not:
Func<string, string> func1 = s => s + "func";
Func<string, string> func2 = s => func1(s);
ViewState["function"] = func2;
It throws a runtime serialization exception: Type 'MyProjectName._Default+<>c__DisplayClass3' in Assembly 'MyProjectName, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' is not marked as serializable.
Now, I can work around this this time, but I'd like to understand why this is happening so that if, in the future, I have no choice but to compose functions before serialization, I'll have a solution.

In JavaScript, for example, you can serialize an object to a JSON string by calling the function JSON. stringify() . CSS values are serialized by calling the function CSSStyleDeclaration. getPropertyValue() .
There are three types of serialization in . Net : Binary Serialization, SOAP Serialization and XML Serialization. Binary serialization is the process where you convert your . NET objects into byte stream.
Serialization is the process of converting an object into a stream of bytes to store the object or transmit it to memory, a database, or a file. Its main purpose is to save the state of an object in order to be able to recreate it when needed. The reverse process is called deserialization.
Capturing modules in a JavaScript function Because a module is just a normal JavaScript value, it is possible to serialize it just like any other value.
What's happening in the second case is that a closure is involved. The use of func1 inside of func2 creates a closure to captured the shared state between the lambdas expressions. Closures are not serializable. When you try and serialize the func it tries to serialize the target object which is the closure and you get your exception.
