<p>There are lots of cases that you can improve. The examples use nullable reference types, but only the <code>WhenNotNull</code> example requires it.</p>

<p>You can make it easy to call methods that return <code>bool</code> and whose signature include an <code>out</code> param with a nullable annotation, using the <a href="https://docs.microsoft.com/dotnet/api/system.diagnostics.codeanalysis.notnullwhenattribute" rel="nofollow">NotNullWhen</a> attribute. In the typical pattern, the attribute tells the compiler that the out parameter is set when the return value is <code>true</code>. In that case, you don't have to check the out parameter for a null reference, if you guard the use of the reference within an <code>if</code> statement, conditional on the return value.</p>
<p>You can search a codebase for this pattern with the following regex, to find opportunities to use <code>NotNullWhen</code>.</p>
