Yeah, I used ildasm to see 0 or 1 is used really.
Seems possible to get methods that use enum and scan through IL of methods
to search for enum member usage through Cecil API? Worth to try?
.method public hidebysig static void Consume(valuetype
[Test.ServiceProvider]Test.ServiceProvider.Enum1 e) cil managed
{
// Code size 15 (0xf)
.maxstack 2
.locals init ([0] bool CS$4$0000)
IL_0000: nop
IL_0001: ldarg.0
* IL_0002: ldc.i4.0*
IL_0003: ceq
IL_0005: ldc.i4.0
IL_0006: ceq
IL_0008: stloc.0
IL_0009: ldloc.0
IL_000a: brtrue.s IL_000e
IL_000c: nop
IL_000d: nop
IL_000e: ret
} // end of method ClassEnum1Consumer::Consume
