Are these methods thread safe

Question

i have the following static class with generic methods and i m wondering if it s safe to use it from different threads and with different objects  i m not sure how this works below the covers so an explanation of would help  public static class Serialization       public static byte   Serialize lt T gt  T obj                using  var ms   new MemoryStream                          Serializer SerializeWithLengthPrefix lt T gt  ms  obj  PrefixStyle Base128               return ms ToArray                         public static T DeSerialize lt T gt  byte   bytes                using  var ms   new MemoryStream bytes                         return Serializer DeserializeWithLengthPrefix lt T gt  ms  PrefixStyle Base128

The only problem with threads is accessing the same object from different threads without synchronization.

If each function only uses parameters for reading and local variables, they don't need any synchronization to be thread-safe.

It follows the convention that static methods should be thread-safe  but actually in v2 that static api is a proxy to an instance method on a default instance  in the case protobuf-net  it internally minimises contention points  and synchronises the internal state when necessary  Basically the library goes out of its way to do things right so that you can have simple code
