ADR0011V01R01 — Per-control culture isolation
Context
Controls that parse or format numbers, dates, and masks must respect a culture.
Changing Thread.CurrentThread.CurrentCulture globally would leak into the host
application’s own formatting.
Decision
A control’s culture is set via .Culture(...) and applied only within that
control’s execution scope. The global/thread culture is never mutated. When no
culture is specified, the control uses the ambient culture read at run time.
Consequences
- Positive: no side effects on the host app’s culture; parallel prompts can use different cultures safely.
- Negative / trade-off: culture must be passed explicitly when it differs from the ambient one; accepted to guarantee isolation.
