📝 This rule is new for StyleCop Analyzers, and was not present in StyleCop Classic.
The name of a parameter in C# does not begin with a lower-case letter.
A violation of this rule occurs when the name of a parameter does not begin with a lower-case letter.
An exception to this rule is made for lambda parameters named _ and __. These parameters are often used to designate a
placeholder parameter which is not actually used in the body of the lambda expression.
If the parameter name is intended to match the name of an item associated with Win32 or COM, and thus needs to begin
with an upper-case letter, place the parameter within a special NativeMethods class. A NativeMethods class is any
class which contains a name ending in NativeMethods, and is intended as a placeholder for Win32 or COM wrappers.
StyleCop will ignore this violation if the item is placed within a NativeMethods class.
To fix a violation of this rule, change the name of the parameter so that it begins with a lower-case letter, or place
the item within a NativeMethods class if appropriate.
