] | Don't check if it was called via a breakpoint - instead, when an instance/service mthod is called, check if the values are actually initialized. Or try to log something from the static constructor and see if it was called.
The static constructor may be called before you have a chance to debug/break on it. | The static constructors should still be called, but this will happen when the hosting program first loads your DLL.
It could be that the host (IIS I presume?) has the service loaded before you added your breakpoint. Try an IISRESET and then check again, you will need to attach to the iis worker process for debugging. |

The case where there is only one digit is easy, there are $9$ possibilities.

The latter are easily found: $111, 222, \ldots, 999$. There are $9$ of these.
Next, consider $11X$ and $1X1$. Then $X$ can be any digit but $1$, giving a total of $9$ possibilities. This gives a total of $18$ numbers.
