 **Exception:** When referring to static members of those types, it is custom to use the full CLS name, e.g. `Int32.Parse()` instead of `int.Parse()`. The same applies to members that need to specify the type they return, e.g. `ReadInt32`, `GetUInt16`.

 Examples include connection strings, server addresses, etc. Use `Resources`, the `ConnectionStrings` property of the `ConfigurationManager` class, or the `Settings` class generated by Visual Studio.

 **Framework Guidelines**  
 
 * Use C# type aliases instead of the types from the `System` namespace (AV2201)  
+* Prefer language syntax over explicit calls to underlying implementations (AV2202)
 * Build with the highest warning level (AV2210)  
 * Use Lambda expressions instead of anonymous functions (AV2221)  
 * Only use the `dynamic` keyword when talking to a dynamic object (AV2230)
