+          Use supportedRuntime tags to explicitly specify the version(s) of the .NET Framework runtime that
+          the custom action should run on. If no versions are specified, the chosen version of the runtime
+          will be the "best" match to what Microsoft.Deployment.WindowsInstaller.dll was built against.
+
+          WARNING: leaving the version unspecified is dangerous as it introduces a risk of compatibility
+          problems with future versions of the .NET Framework runtime. It is highly recommended that you specify
+          only the version(s) of the .NET Framework runtime that you have tested against.
+
+          Note for .NET Framework v3.0 and v3.5, the runtime version is still v2.0.
+
+          In order to enable .NET Framework version 2.0 runtime activation policy, which is to load all assemblies
+          by using the latest supported runtime, @useLegacyV2RuntimeActivationPolicy="true".
