Subject: [PATCH] Simple Injector sample: .NET 10, SimpleInjector 5.6.0,
 lifestyle mismatch test

Retarget both projects to net10.0, update SimpleInjector to 5.6.0 and the test packages, use target-typed new and an expression-bodied property in ContainerManager, and add a test that pins the Verify() lifestyle mismatch failure.
