Why is FileVersionInfo.FileMinorPart (an int) documented in MSDN to possibly be null?

Question

In MSDN Diagnostics.FileVersionInfo it says that, for example, ProductMinorPart returns an int or null if the value is undefined. However it's not a Nullable<int> - how can it return null? I checked with ILDasm, and the definition is a normal int, no Nullable...

Am I missing something?

Answer 1

No, you don't appear to be missing something. I'd say the documentation is inaccurate.

It appears that the property returns 0 if the minor part is missing, or if the entire version is missing all together.
