+#### Special debugger side considerations for .NET 5.0+
+
+Custom Visualizers transfer data between the *debuggee* and *debugger* sides through binary serialization using
+the <xref:System.Runtime.Serialization.Formatters.Binary.BinaryFormatter> class by default. However, that kind of
+serialization is being curtailed in .NET 5 and above due to security concerns regarding its *unfixible* vulnerabilities.
+Moreover, it has been marked completely obsolete in ASP.NET Core 5 and its usage will throw as described in the
+[ASP.NET Core Documentation](/dotnet/core/compatibility/core-libraries/5.0/binaryformatter-serialization-obsolete).
+Hence, this section describes the necessary steps that should be taken so that your visualizer is still supported in
+this scenario.
+
+- For compatibility reasons, the <xref:Microsoft.VisualStudio.DebuggerVisualizers.DialogDebuggerVisualizer.Show%2A> method
+that was overridden in the preceding section still takes in an <xref:Microsoft.VisualStudio.DebuggerVisualizers.IVisualizerObjectProvider>. Nonetheless, it is actually of type <xref:Microsoft.VisualStudio.DebuggerVisualizers.IVisualizerObjectProvider2>.
+Therefore, cast the `objectProvider` object to the updated interface.
+
+- When sending objects, like commands or data, to the *debuggee-side* use the `IVisualizerObjectProvider2.Serialize` method
+to pass it to a stream, it will determine the best serialization format to use based on the runtime of the *debuggee* process.
+Then, pass the stream to the `IVisualizerObjectProvider2.TransferData` method.
+
+- If the *debuggee-side* visualizer component needs to return anything to the *debugger-side*, it will be located in the
+<xref:System.IO.Stream> object returned by the <xref:Microsoft.VisualStudio.DebuggerVisualizers.IVisualizerObjectProvider.TransferData%2A>
+method. Use the `IVisualizerObjectProvider2.GetDeserializableObjectFrom` method to get an
+<xref:Microsoft.VisualStudio.DebuggerVisualizers.IDeserializableObject> instance from it and process it as required.
+
+Please refer to the [Special debuggee side considerations for .NET 5.0+](#special-debuggee-side-considerations-for-net-50)
+section to learn what other changes are required on the *debuggee-side* when using Binary Serialization is not supported.
+
+> [!NOTE]
+> If you would like more information on the issue, see the [BinaryFormatter security guide](/dotnet/standard/serialization/binaryformatter-security-guide).

+serialization method used by default. Please read this [section](#special-debugger-side-considerations-for-net-50) before continuing.
+
+- If the visualizer implements the <xref:Microsoft.VisualStudio.DebuggerVisualizers.VisualizerObjectSource.TransferData%2A> method, 
+use the newly added <xref:Microsoft.VisualStudio.DebuggerVisualizers.VisualizerObjectSource.GetDeserializableObject%2A> method that
+is available in the latest version of `VisualizerObjectSource`. The <xref:Microsoft.VisualStudio.DebuggerVisualizers.IDeserializableObject>
+it returns helps to determine the object's serialization format (binary or JSON) and to deserialize the underlying object so that it may be used.
+
+- If the *debuggee-side* returns data to the *debugger-side* as part of the `TransferData` call, serialize the response to the
+*debugger-side's* stream via the <xref:Microsoft.VisualStudio.DebuggerVisualizers.VisualizerObjectSource.Serialize%2A> method.
