What is the DynamicallyAccessedMembers attribute?

DynamicallyAccessedMembers tells the .NET trimmer and AOT compiler which members of a Type you reach by reflection, so they are kept instead of trimmed away. It turns a silent runtime MissingMethodException into a build-time IL2070 warning. Here is what the attribute does, how the data-flow analysis behind it works, and how to annotate parameters, fields, and generic type parameters correctly.

What is Native AOT and what does it cost you?

Native AOT compiles your .NET app to a single self-contained native binary with no JIT, buying fast startup and a small memory footprint. The price is a C toolchain at build time, slower publishes, per-RID builds, no reflection or Reflection.Emit, mandatory trimming, and no Dynamic PGO. Here is the full ledger.

.NET 11 Raises the Minimum CPU Baseline to x86-64-v2

.NET 11 Preview 4 drops support for pre-2013 x86/x64 chips and bumps the JIT baseline to x86-64-v2. Here is what breaks, why, and how to check your hardware before you upgrade.

Native AOT vs ReadyToRun vs JIT in .NET 11: which should you ship?

Plain JIT with Dynamic PGO wins steady-state throughput, ReadyToRun cuts startup with zero code changes, and Native AOT gives the smallest, fastest-starting binary at the cost of reflection and dynamic code. Pick by deployment shape, not raw benchmarks.

Fix: PlatformNotSupportedException: Operation is not supported on this platform in Native AOT

Native AOT strips the JIT and the interpreter, so reflection emit, expression-tree compilation, and unseen MakeGenericType throw at runtime. Find the call via IL3050 and replace it with a source generator or a pre-baked path.
