Class GuidSerializer
Type serializer for Guid values. Converts each GUID to and from the
standard hyphenated 8-4-4-4-12 string representation (format specifier "D"),
for example 550e8400-e29b-41d4-a716-446655440000.

Syntax
public sealed class GuidSerializer : TypeSerializerBase<Guid>, ITypeSerializer<Guid>, ITypeSerializerRemarks
The "D" format is chosen over "B" (braces) or "N" (no hyphens)
for maximum human-readability and cross-platform JSON compatibility. On read,
Parse(string) accepts all standard Guid format strings, so data
produced by other serializers using a different format will still deserialize correctly.
Use the shared Instance singleton rather than creating new instances;
GuidSerializer carries no mutable state and is safe to share across threads.
Fields
Instance
Shared, reusable singleton instance of GuidSerializer.
Prefer this over allocating a new instance wherever a GuidSerializer is needed.
