- 15. How to create New Type Provider
- 16. Before You Start The type provider mechanism is primarily designed for injecting stable data and service information spaces into the F# programming experience. materials are from MSDN
- 17. Before You Start This mechanism isn’t designed for injecting information spaces whose schema changes during program execution in ways that are relevant to program logic. materials are from MSDN
- 18. Before You Start: Ask yourself questions • Do you have a schema for your information source? If so, what’s the mapping into the F# and .NET type system? • Can you use an existing (dynamically typed) API as a starting point for your implementation? • Will you and your organization have enough uses of the type provider to make writing it worthwhile? Would a normal .NET library meet your needs? • How much will your schema change? • Will it change during coding? • Will it change between coding sessions? • Will it change during program execution? materials are from MSDN
