			&lt;/tbody&gt;
&lt;/table&gt;
&lt;/div&gt;
&lt;p/&gt;
&lt;p&gt;&#160;&lt;/p&gt;

&lt;p&gt;The ImmutableTypeClassMapConvention refuses to map such a class, because when obtaining the properties of a type, it &lt;a href=&quot;https://github.com/mongodb/mongo-csharp-driver/blob/v2.7.0/src/MongoDB.Bson/Serialization/Conventions/ImmutableTypeClassMapConvention.cs#L42&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;calls the GetProperties&lt;/a&gt; method with no parameters. According to the MSDN documentation,&#160;&lt;a href=&quot;https://docs.microsoft.com/en-us/dotnet/api/system.type.getproperties?view=netcore-2.1&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;both instance and static properties&lt;/a&gt; of a type are returned in this case.&#160;&lt;/p&gt;

&lt;p&gt;The suggested fix is to consider instance properties only by setting the correct BindingFlags.&lt;/p&gt;

&lt;p&gt;&#160;&lt;/p&gt;

&lt;p&gt;I&apos;ve edited line 42 to be:&lt;/p&gt;

&lt;p&gt;var properties = typeInfo.GetProperties(BindingFlags.Instance | BindingFlags.Public );&lt;/p&gt;

&lt;p&gt;and this now solves this problem.&lt;/p&gt;

&lt;p&gt;See PR&#160;&lt;a href=&quot;https://github.com/mongodb/mongo-csharp-driver/pull/350&quot; class=&quot;external-link&quot; target=&quot;_blank&quot; rel=&quot;nofollow noopener&quot;&gt;https://github.com/mongodb/mongo-csharp-driver/pull/350&lt;/a&gt;&lt;/p&gt;
