Ignore parts of the code

In most solutions, there are parts of the code where you want to disable some or all of JetBrains Rider features. This topic lists all available ways to make JetBrains Rider ignore specific parts of the code.

Disable code inspection for parts of the code

ScenarioMinimize unwanted results in design-time code inspection and code inspection in specific scope by ignoring parts of code that you are not going to improve.
