-Starting with .NET Aspire 9, the preceding example could instead use the .NET Aspire SDK.
+The `Project/Sdk` attribute and `Sdk` element enable additive SDKs. Consider the following example, where the .NET Aspire SDK (`Aspire.AppHost.Sdk`) is added to the project atop the `Microsoft.NET.Sdk`:
 
 ```xml
 <Project Sdk="Microsoft.NET.Sdk">
 
-    <Sdk Name="Aspire.AppHost.Sdk" Version="9.0.0-rc.1.24511.1" />

+In the preceding project file, both SDKs are used to resolve dependencies in an additive nature. For more information, see [.NET Aspire SDK](/dotnet/aspire/fundamentals/dotnet-aspire-sdk)
 
 To specify an SDK that comes from NuGet, include the version at the end of the name, or specify the name and version in the *global.json* file.
