MsgPack001 Avoid static default for MessagePackSerializerOptions

Without an explicit MessagePackSerializerOptions argument, a shared/static default will be assumed which any other code in the entire AppDomain or process can alter, causing malfunction in your invocation.

Examples of patterns that are flagged by this analyzer

MessagePackSerializer.Serialize(obj);

Solution

Specify a MessagePackSerializerOptions value that comes from an immutable static property, field or local variable.

MessagePackSerializer.Serialize(obj, MessagePackSerializerOptions.Standard);
