Another Gradle process holds ~/.gradle/caches/journal-1 and cannot hand it over. Find the Owner PID, kill that daemon, and stop deleting .lock files: that only moves the error.

The official google_mobile_ads sample renders nothing until onAdLoaded, so your content jumps by 150 dp seconds after the screen appears. Ask for the anchored adaptive size first, reserve it with a SizedBox, persist the height across launches, and only then load the ad. Measured on Flutter 3.44.8 with google_mobile_ads 9.1.0.

Orleans 10.4.0 adds StreamSubscriptionStartPosition.EarliestAvailable, so a new stream subscriber can replay what is still in the pulling agent's queue cache. The release also changes RPC argument wire IDs, request-latency metrics, and SQLite persistence scripts.

Tool calling is a protocol, not magic: the model emits a structured request matching a JSON Schema you supplied, your code runs it, and the result goes back as a message. The schema and its descriptions are rendered into the model's prompt and, with strict mode, into a decoding grammar, so they shape behaviour more reliably than any system-prompt instruction. Here is how it works on claude-sonnet-5-5 and OpenAI strict mode, with schema patterns that make invalid calls impossible.

A signed assembly must name its friend by the full 320-character public key, not the token, or the build fails with CS1726 or CS0281. Get the key with sn -p and sn -tp, or with a cross-platform .NET script, then put it in the Key metadata of an InternalsVisibleTo item in the .csproj. Covers the PublicKey property fallback, Moq's DynamicProxyGenAssembly2 key, and the line-break trap.

Use SystemEvents.SessionSwitch in a desktop or console app, override OnSessionChange in a Windows service, or hook WM_WTSSESSION_CHANGE yourself. Covers .NET 10 code for all three, the hidden '.NET System Events' thread, why services see logon but desktop apps do not, out-of-order notifications, and how to query the current lock state with WTSQuerySessionInformation.

A SET statement run once is wiped by DISCARD ALL the moment Npgsql returns the connection to its pool. Put search_path and statement_timeout in the startup packet with the Search Path and Options connection string keywords, fall back to ALTER ROLE or a ConnectionOpened interceptor, and know why UsePhysicalConnectionInitializer silently loses its SET.

NUnit 5.0.0 makes Assert.ThrowsAsync, CatchAsync and DoesNotThrowAsync truly asynchronous. Forget the await and the assertion never runs. Here is what breaks, what the NUnit.Analyzers NUnit2059 rule catches, and the other NUnit 5 changes to check before upgrading.

In a workflow, your code decides the next step and the model fills in each step. In an agent, the model decides the next step and your code only executes it. That one question (who owns the control flow) determines cost, latency, testability and failure modes. Here is the distinction as Anthropic, Microsoft Agent Framework and LangGraph define it, with the same task built both ways in Python against claude-haiku-4-5 and claude-sonnet-5-5.

Check IsCompleted first and read the result through GetAwaiter().GetResult(), which costs 0 bytes. Only fall back to blocking when the ValueTask is still pending, and do that with a cached event and UnsafeOnCompleted instead of AsTask(), which allocates 72 to 208 bytes per call. Measured on .NET 10 and .NET 11 RC1.
