The C# code includes an empty string, written as “”.
A violation of this rule occurs when the code contains an empty string. For example:
string s = "";
This will cause the compiler to embed an empty string into the compiled code. Rather than including a hard-coded empty string, use the static string.Empty property:
string s = string.Empty;
How to Fix Violations
To fix a violation of this rule, replace the hard-coded empty string with string.Empty.
