Strongly-typed identifiers improve type safety by preventing accidental parameter order mistakes that the compiler can't catch with primitive types. This post walks through implementing strongly-typed IDs in C# using a generic base class, then integrating them with Marten (a .NET document/event store). Key challenges include Marten's requirements for public getters/setters and specific ID types. The solution uses the [Identity] attribute to redirect Marten's identifier to the underlying primitive value, configures non-public member serialization, and shows a full Event Sourcing aggregate example with the pattern applied.
