I have a Regex to not allow spaces and some special chars., but the validation fires even when Uppercase letters are entered.

[RegularExpression(@"^[^<>.,?;:'()!~%-_@#%/*""\s]+$")]
public string FirstName { get; set; }

You need to remove the - (minus sign). %-_ means between % (char code 37) and _ (char code 95) which includes upper case characters.

If you want to exclude the minus symbol, then you need to escape it using \-.

The attribute should be

[RegularExpression(@"^[^<>.,?;:'()!~%\-_@#/*""\s]+$")]
public string FirstName { get; set; }
