 To use source-generated metering, create a class that defines the names and dimensions of the metrics your code can produce. Then, create the class with `partial` method signatures.
 
-The code generator automatically generates the code, which exposes strongly typed metering types and methods that you can invoke to record metric values. The generated methods are implemented in a highly efficient form, which reduces computation overhead as compared to traditional metering solutions.
