Infer field nullability from NRT annotations</h3>
+<p>Since 7.9 you can enable the inference of the field nullability from the Null Reference Types (NRT)
+annotations when defining the field with expression. To enable the feature set the<br>
+<code class="language-text">GlobalSwitches.InferFieldNullabilityFromNRTAnnotations</code> to <code class="language-text">true</code>.</p>
+<p>For example, given the following code</p>
+<div class="gatsby-highlight" data-language="c#"><pre class="language-c#"><code class="language-c#">public class Person
+{
+    public string FullName { get; set; }
+    public string? SpouseName { get; set; }
+    public IList&lt;string&gt;? Children { get; set; }
+}
+
+public class PersonGraphType : ObjectGraphType&lt;Person&gt;
+{
+    public PersonGraphType()
+    {
+        Field(p =&gt; p.FullName);
+        Field(p =&gt; p.SpouseName);
+        Field(p =&gt; p.Children);
+    }
+}</code></pre></div>
