+
+There are also some convenience extension methods on framework types that can be useful for various tasks. They are explained below:
+
+## Extensions for shortening numbers
+
+You may want to convert the numeric values to its equivalent string representation. The output will be an abbreviated string. For example, you may want to represent `1,000,000` as `1M` or `1,000` as `1K`. This can be done as shown below:
+
+```cs
+long number = 1_000;
+var converted = number.ToStringAbbreviated();
+Console.WriteLine(converted); // 1K
+```
+
+You can use overloads for `ToStringAbbreviated(...)` to supply an `IFormatProvider` if you need to abbreviate a number using culture-specific formatting information.
+
+## Extensions for string protection
+
+Sometimes you may want to mask certain portions of strings that may contain sensitive information. An example is a password or an authentication key to access an API. An example of how you can do this is shown below:
+
+```cs
+var key = "EcsmGa/wXv/HlA==";
+var result = key.Protect();
+Console.WriteLine(result); // Ecs*************
+```
+
+By default, only the first 20% of the string will be kept as is. The remaining characters will be replaced with asterisks (*). To alter this default behavior you can supply different values to the following parameters:
+
+- `toKeep`: Specifies how many of the characters in the string aren't replaced with the replacement character (which is an asterisk by default) as a percentage.
+- `position`: The position of the string to protect. By default, the `StringProtectionPosition` is `End`. You can alter this to `Middle` or `Start`.
+- `replacementChar`: The character to replace the protected string characters with. By default, it is an asterisk (*).
+- `replacementLength`: The length of the replacement string using the replacement characters.
+
+## Extensions for splitting a string in Pascal casing into multiple words
+
+[Pascal case](https://www.pluralsight.com/blog/software-development/programming-naming-conventions-explained#pascal-case).
+
+```cs
+var str = "HomeAndAway";
+var result = str.PascalSplit();
+Console.WriteLine(result); // Home And Away
+```
+
+By default, the string will be split, and a single whitespace will be inserted in between the words. If you'd like to change the separator that is inserted between the words you can set the `separator` parameter in `PascalSplit(...)`.
+
+## Extensions to the get the value declared on the Enum using EnumMemberAttribute
+
+For example:
+
+```cs
+public enum Platform
+{
+    [EnumMember(Value = "ios")]
+    iOS,
+
+    Android
+}
+```
+
+In the declared enumerations to represent the iOS and Android platforms. Note that only the iOS member has an `EnumMemberAttribute` annotated on it.
+
+```cs
+var platform = Platform.iOS;
+var result = tt.GetEnumMemberAttrValue();
+Console.WriteLine(result); // ios
+
+platform = Platform.Android;
+result = tt.GetEnumMemberAttrValue();
+// result is null here
+```
+
+Since the `iOS` member is annotated with an `EnumMemberAttribute`, `ios` is returned as expected. However, the `Android` member doesn't have that annotation and thus the value that will be returned will be `null`. If you'd like to return the default value in lower case format when there are members without an `EnumMemberAttribute` annotation:
+
+```cs
+var platform = Platform.iOS;
+var result = tt.GetEnumMemberAttrValueOrDefault();
+Console.WriteLine(result); // ios
+
+platform = Platform.Android;
+result = tt.GetEnumMemberAttrValueOrDefault();
+Console.WriteLine(result); // android
+```
