InterfaceGenerator

A simple source generator that creates interfaces by implementations. Useful for when you need an interface purely for the sake of mocking, or maybe you're not sure if you'll need the abstraction later on.

Inspired by net_automatic_interface

Add as PackageReference

When you add this reference be sure you include compile asset and exclude runtime.

<PackageReferenceInclude="CronosCore.InterfaceGenerator"Version="1.1.0"IncludeAssets="compile; build; native; contentfiles; analyzers; buildtransitive" />

Example user implementation

[GenerateAutoInterface]publicclassSampleService:ISampleService{publicdoubleMultiply(doublex,doubley){returnx*y;}publicintNiceNumber=>69;}

Auto generated interface:

publicpartialinterfaceISampleService{doubleMultiply(doublex,doubley);intNiceNumber{get;}}

Supports

• Methods, properties, indexers.
• Default arguments, params arguments.
• Generic types and methods.
• XML docs.
• Explicit interface names (using the Name property on GenerateAutoInterface).
• Explicit interface visibility (using the VisibilityModifier property on GenerateAutoInterface).
• Explicitly excluding a member from the interface (using [AutoInterfaceIgnore]).

Missing

• Events.
• Nested types.
• Probably a bunch of edge cases I forgot about.
