For an F# Type Provider, how do I make a relative path work as a static parameter?

问题

Is there a good way to make a relative path work for both the type provider while programming and msbuild while building?

//type AddressBookProto = Froto.Gen.ProtoGen< @"test\addressbook1.proto"> // VS GUI
//type AddressBookProto = Froto.Gen.ProtoGen< @"..\test\addressbook1.proto"> // Build
type AddressBookProto = Froto.Gen.ProtoGen< @"C:\Users\taggartc\froto\froto\test\addressbook1.proto">

回答1:

You could use #if

#if DEBUG //or similar constant
    type AddressBookProto = Froto.Gen.ProtoGen< @"test\addressbook1.proto">
#else
    type AddressBookProto = Froto.Gen.ProtoGen< @"..\test\addressbook1.proto">
#endif

Now you just need to define appropriate conditionals.
