+When using WireMock.Net in a Xamarin test project, you can encounter these errors:
+
+## Could not load file or assembly 'System.Memory, Version=4.0.1.0
+```
+WireMock.Exceptions.WireMockException : Service start failed with error: One or more errors occurred.

+### Solution:
+
+Adding assembly binding redirects to the app.config for the assemblies which have an error.
+Like:
+``` xml
+<runtime>
+    <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
+      <dependentAssembly>
+        <assemblyIdentity name="System.Memory" publicKeyToken="cc7b13ffcd2ddd51" culture="neutral" />
+        <bindingRedirect oldVersion="4.0.2.0-4.0.3.0" newVersion="4.0.3.0" />
+      </dependentAssembly>
+
+      <dependentAssembly>
+        <assemblyIdentity name="System.Buffers" publicKeyToken="cc7b13ffcd2ddd51" culture="neutral" />
+        <bindingRedirect oldVersion="4.0.2.0-4.0.3.0" newVersion="4.0.3.0" />
+      </dependentAssembly>
+
+      <dependentAssembly>
+        <assemblyIdentity name="System.Numerics.Vectors" publicKeyToken="b03f5f7f11d50a3a" culture="neutral"/>
+        <bindingRedirect oldVersion="4.0.0.0-4.1.4.0" newVersion="4.1.4.0"/>
+      </dependentAssembly>
+    </assemblyBinding>
+  </runtime>
+```
