.NET: Are there any differences between InvariantCulture and en-US?

Question

Given the following two cultures:

CultureInfo c1 = InvariantCulture;
CultureInfo c2 = new CultureInfo("en-US");

and i were to examine every piece of information specific to both cultures, e.g.:

c1.DateTimeInfo.ShortDatePattern;
c2.DateTimeInfo.ShortDatePattern;

c1.DateTimeInfo.LongDatePattern;
c2.DateTimeInfo.LongDatePattern;

c1.NumberFormat.CurrencyDecimalDigits;
c2.NumberFormat.CurrencyDecimalDigits;

c1.TextInfo.IsRightToLeft;
c2.TextInfo.IsRightToLeft;

Would i find any differences?

In other words, is the InvariantCulture, for all purposes, identical to the "en-US" culture?

Answer 1

Yes.

For example: InvariantCulture uses the international symbol for currency: "¤" versus the dollar sign: "$" when formatting currency.

For the most part, however, they're very similar.
