Code Inspection: Use preferred 'var' style (when type is simple)

This code inspection checks violations of your preferences for using var or explicit type in local variable declarations. Specifically, it checks variable declarations of C# built-in types (bool, double, string, etc.).

Using implicitly typed local variables (also known as var keyword) introduced in C# 3.0 has become quite popular as it improves readability in many scenarios. By default, JetBrains Rider also encourages using of var keyword, but preferences of its usage are flexibly configurable — for example, you can opt for using explicit types in specific cases or everywhere and JetBrains Rider will help you enforce your preferences.

For more information about configuring and enforcing your preferences of using var or explicit types in local variable declarations, see Code Syntax Style: Implicit/Explicit Typing ('var' Keyword).
