Linting on Xamarin
Linting is the process of running a tool which analyzes your code for potential errors. Generally, each problem detected by the tool is reported with a description message and a severity level. This allows you to quickly prioritize the critical improvements that need to be made. Everyone benefits from higher code quality, plus it improves the accuracy of assistive technologies.
With Xamarin, you can can use a lint tool with Xamarin.Android projects. Set the property AndroidLintEnabled to true in your .csproj.
Unfortunately, there is no built-in lint tool for Xamarin.iOS projects.
<AndroidLintEnabled>true</AndroidLintEnabled>
