TwinCat 3 unions

[jaapieaapie1]

In your README.md you mention that oneof wouldn't be possible in twincat because you don't have proper unions in twincat. But unions exist in twincat 3 and would work you would just need to generate a struct containing a field which indentifies which type is set and the union which contains all the possible types in the oneof.

True!
I initially thought of discriminated union types, not the union we have in TC3.
After revisiting the Oneof section and comparing it with the generated C# code, it turns out we don’t need a union at all— the active value is tracked using an enum. So implementing this shouldn’t be an issue.
