-### Improvements to Minimal APIs Validation
-
+#### Validation with record types
 <!-- https://github.com/dotnet/aspnetcore/pull/61193 -->
 <!-- https://github.com/dotnet/aspnetcore/pull/61402 -->
-Beginning in Preview 4, ASP.NET Core supports validation on record types. With this enhancement,
-inputs to API endpoints defined using `record` types are now validated automatically, in the same way as
-class types.
+
+Minimal APIs also support validation with C# record types. Record types can be validated using attributes from the <xref:System.ComponentModel.DataAnnotations?displayProperty=fullName> namespace, similar to classes. For example:
+
+```csharp
+public record Product(
+    [Required] string Name,
+    [Range(1, 1000)] int Quantity);
+```
+
+When using record types as parameters in Minimal API endpoints, validation attributes are automatically applied in the same way as class types:
+
+```csharp
+app.MapPost("/products", (Product product) =>
+{
+    // Endpoint logic here
+    return TypedResults.Ok(product);
+});
+```
