A bit more information...
If I use ildasm and compare the result with that from a similar C# program, I see that, in F#, each property has its own block, where in C# they share one:
F#:
1 2 3 4 5 6 7 8
.property instance void X(int32) { .set instance void Action/_A::set_X(int32) } // end of property _A::X .property instance int32 X() { .get instance int32 Action/_A::get_X() } // end of property _A::X
C#:
1 2 3 4 5
.property instance int32 x() { .get instance int32 cslib._A::get_x() .set instance void cslib._A::set_x(int32) } // end of property _A::x
If I modify the F# IL to make it look like the C# IL and compile that, then I get the type library that I'm hoping for.
Hi Jason,
Yes, this is a discrepency in the exact metadata we generate for properties - this is the first time we've seen that this is significant. I've recorded it as bug 1061 in our internal database. At some point we hope to make this database accessible in some form so you'll be able to track our progress on this issue, but we haven't done that just yet.
Kind regards & thanks for the detailed bug report

I am experimenting with writing a library in F# that will be used by COM clients (VB6 and VBA). I have had good luck, except with get/set properties that are declared in interfaces, as shown in the sample code below. In this case, the type library produced by regasm.exe has different names for the getter and setter, e.g. X and X_2. If I declare a get/set property in the class instead of interface, then it works correctly, with both the getter and setter sharing the same name.
Any advice?
Aside:
I am using an interface in order to avoid exposing the ToString, GetHashCode, Equals, and GetType members from obj. A different approach that I tried was to use only a class, but within that class I supplied an overload of each of the obj methods and marked them as ComVisible(false)... almost... I could not override GetType. If there is no way to have get/set properties in an interface appear to a COM client with the same name, is there a way to expose a class's interface to COM without the obj members?
thanks,
Jason
