+# SDK in .NET 11 RC 2 - Release Notes
+
+.NET 11 RC 2 improves file-based program configuration and launch-profile arguments:
+
+- [Quoted file-level directive values](#quoted-file-level-directive-values)
+- [MSBuild properties in launch-profile arguments](#msbuild-properties-in-launch-profile-arguments)
+
+## Quoted file-level directive values
+
+File-based programs can use quoted values containing spaces in `#:property` directives. The `#:package`, `#:project`, and `#:ref` directives also accept trailing `Name=Value` tokens for MSBuild item metadata. This example uses the `Aliases` metadata on a package directive and references the package through the resulting C# extern alias ([dotnet/sdk #55960](https://github.com/dotnet/sdk/pull/55960)).
+
+```csharp
+#:property Company="RC2 Validation Team"
+#:property AssemblyTitle="RC2 Directive Validation"
+#:package System.CommandLine@2.0.1 Aliases=CommandLine
+
+extern alias CommandLine;
+using System.Reflection;
+
+string? company = Assembly.GetExecutingAssembly()
+    .GetCustomAttribute<AssemblyCompanyAttribute>()?.Company;
+var nameOption = new CommandLine::System.CommandLine.Option<string>("--name");
+var command = new CommandLine::System.CommandLine.RootCommand();
+command.Options.Add(nameOption);
+string? name = command.Parse(args).GetValue(nameOption);
+if (company != "RC2 Validation Team" || name != "RC2")
+{
+    throw new Exception($"Unexpected metadata or argument: {company}, {name}.");
+}
+
+Console.WriteLine($"Company: {company}; name: {name}");
+```
+
+Run the file with `dotnet run Program.cs -- --name RC2`. The quoted value becomes the generated assembly's `Company` metadata, and `System.CommandLine` parses the supplied option through the `CommandLine` alias.
+
+See the [file-based apps documentation](https://learn.microsoft.com/dotnet/core/sdk/file-based-apps) for supported directives and the broader workflow.
+
+## MSBuild properties in launch-profile arguments
+
+`dotnet run` now expands MSBuild properties in a launch profile's `commandLineArgs` using the evaluated project. For example, a profile argument such as `--name $(AssemblyName)` receives the project's assembly name when you run `dotnet run --launch-profile <profile>` ([dotnet/sdk #56064](https://github.com/dotnet/sdk/pull/56064)).

+# SDK release-note validation
+
+Run `dotnet run Program.cs -- --name RC2` from this directory with SDK `11.0.100-rc.2.26475.137`. The file-based app checks that a quoted file-level property becomes generated assembly metadata and uses `System.CommandLine` through a C# extern alias supplied by trailing `Aliases=CommandLine` package metadata.
+
+To verify MSBuild property expansion in file-based launch-profile arguments, run `dotnet run --file launch-profile/Program.cs --launch-profile AssemblyName` from this directory. The adjacent `Program.run.json` defines the profile, and the file-based program declares `AssemblyName`; it exits with an error if the property is not expanded.
