  2. CanvasKit vs skwasm for Flutter web in 2026: which renderer should you ship?

    (Start Debugging)

    Ship skwasm with flutter build web --wasm when your dependencies compile to Wasm: it downloads less and rendered 36% more frames than CanvasKit on a heavy scene.

  3. SQL Server compatibility level 150 vs 160: what changes for EF Core 11 queries

    (Start Debugging)

    EF Core 11 now defaults UseSqlServer to compatibility level 160, which puts LEAST, GREATEST and two-argument LTRIM/RTRIM into your SQL, including every Take(n).FirstOrDefault().

  4. Fix: Unexpected failure parsing device information from adb output in Flutter

    (Start Debugging)

    Flutter 3.47.0 cannot parse adb rows whose serial is 22+ characters, so wireless and some USB Android devices vanish.

  5. Fix: GitHub Copilot can't see a file because a content exclusion rule excludes it

    (Start Debugging)

    "File is configured to be ignored by Copilot" or "Some files were excluded from the context" means a content exclusion rule matched.

  6. Fix: UIKitThreadAccessException from MediaPicker.PickPhotosAsync when selecting multiple photos in .NET MAUI iOS

    Picking 2 or more photos on iOS throws UIKitThreadAccessException in MAUI 10.0.100 and 10.0.101.

  8. Fix: EF Core MigrateAsync and CanConnectAsync keep retrying on 'Login failed for user' for 60 seconds

    (Start Debugging)

    EF Core's SQL Server existence check retries error 18456 for a full minute, with or without EnableRetryOnFailure.

  9. Fix: ASP.NET Core API endpoints return 401 instead of redirecting to the login page after upgrading to .NET 10

    (Start Debugging)

    In .NET 10 cookie auth answers API-style endpoints with 401/403 instead of a login redirect.

  10. Fix: a PreToolUse hook returns "allow" but a deny rule still blocks the tool call in Claude Code

    (Start Debugging)

    Since Claude Code 2.1.77 a PreToolUse hook's allow cannot override a deny or ask rule.

  11. Fix: flutter doctor --android-licenses says 'The --licenses option is no longer needed' with cmdline-tools 23

    (Start Debugging)

    cmdline-tools 23.0 retired sdkmanager --licenses, so Flutter before 3.47.3 reports license status unknown.

  12. Microsoft.Extensions.AI 10.10 Fails Evaluation Metrics the Judge Never Scored

    (Start Debugging)

    Microsoft.Extensions.AI.Evaluation.Quality 10.10.0 now marks unparseable and out-of-range quality scores as failed, and Microsoft.Extensions.AI.OpenAI 10.10.0 drops the Assistants adapter.

    (Start Debugging)

    EF Core 11 is compiled against Microsoft.Data.SqlClient 7.0.0.0, but a 6.x copy won the restore or the deploy.

  15. Fix: a coding agent loops forever re-running a check it can't satisfy

    (Start Debugging)

    When a Stop hook, /goal condition, or CI-style gate demands a check the agent's environment can never pass, Claude Code keeps re-running it until the 8-consecutive-block cap (2.1.143+) ends the turn.

  16. How to Create and Extract ZIP Files Asynchronously with the ZipArchive Async APIs in .NET 11

    (Start Debugging)

    Agent Execution Timed Out, ERROR_EXTENSION_HOST_TIMEOUT and Timeout waiting for EverythingProvider are one failure: Cursor's extension host missed its 60 s startup budget.

  22. Agent Framework 1.21: LocalCodeAct Stops Handing Your Host Environment to Model-Written Python

    (Start Debugging)

    Microsoft Agent Framework .NET 1.21.0 ships Microsoft.Agents.AI.LocalCodeAct 1.21.0-preview.260911.1, which no longer lets the CodeAct Python subprocess inherit the parent environment when Environment is null.

  23. Lookup vs Dictionary> for duplicate keys in C#

    (Start Debugging)

    Use ToLookup when you group once and only read: it is immutable, returns an empty sequence for missing keys, accepts null keys and keeps first-seen order.

  24. Native json column vs nvarchar(max) for storing JSON in SQL Server with EF Core 11

    (Start Debugging)

    Use the native json type on SQL Server 2025 and Azure SQL: EF Core 11 gets JSON_CONTAINS, typed JSON_VALUE, in-place modify() and JSON indexes out of it.

  27. .NET 11 RC 1 Makes dotnet publish Container Images Reproducible

    (Start Debugging)

    The .NET 11 RC 1 SDK honors SOURCE_DATE_EPOCH when publishing container images, strips the process id from layer tar headers, and skips blob uploads when the registry already has the manifest.

  28. Fix: Flutter web serves a stale cached build after reloading the browser tab

    (Start Debugging)

    A reload only revalidates index.html, so an unhashed main.dart.js keeps coming from the browser cache.

  29. Fix: The argument type 'TextTheme' can't be assigned to the parameter type 'TextTheme?' with google_fonts

    (Start Debugging)

    Your app imports material_ui but google_fonts 8.2.1 still returns the SDK TextTheme.

  30. Fix: remote MCP server returns 401 invalid_token because the token's aud doesn't match the canonical server URL

    (Start Debugging)

    OAuth succeeded but every MCP call gets 401 invalid_token?

    The SignalR authentication refresh APIs are finalized in .NET 11 RC 1, with renamed callbacks on HubConnection, a TypeScript client, and Blazor Server circuits that pick up the refreshed ClaimsPrincipal automatically.

    EF Core's build-time model generation re-entered MSBuild until RAM ran out.

  36. Fix: IsAuthenticated is false and RemoteUserAccount is null in Blazor WebAssembly after an MSAL upgrade

    (Start Debugging)

    Microsoft.Authentication.WebAssembly.Msal 10.0.8, 9.0.16 and 8.0.27 moved to msal.js 4, whose async init races itself.

  37. Fix: Could not create Dart VM instance in a Flutter release build after flutter upgrade

    (Start Debugging)

    Since August 21, 2026 mentioning @GitHub in Slack starts a Copilot cloud agent session the whole channel can steer.

  39. Fix: The complex type collection must be initialized to a non-null value

    (Start Debugging)

    On EF Core 10.0.x, nulling a complex property that holds a two-element collection inside a ToJson complex collection breaks DetectChanges.

  40. Fix: Complex entry original ordinal '-1' is invalid when saving a ToJson complex collection

    (Start Debugging)

    Upgrade Microsoft.EntityFrameworkCore to 10.0.10 or later.

  41. Fix: AS JSON option can be specified only for column of nvarchar(max) type in WITH clause

    (Start Debugging)

    EF Core emits [col] json '$.path' AS JSON inside OPENJSON WITH, which Azure SQL rejects with Msg 13618.

  42. .NET 11 RC 1 Lets You SIGTERM a Child Process Without P/Invoke

    (Start Debugging)

    Signal, WaitForExitStatus, and ProcessExitStatus land directly on System.Diagnostics.Process in .NET 11 RC 1, so graceful shutdown of a child process no longer needs a kill P/Invoke or a SafeProcessHandle detour.

  43. Rider 2026.3 EAP: dotCover Finally Measures TUnit Coverage

    (Start Debugging)

    The Rider 2026.3 Early Access Program opened on September 7, 2026.

  44. How to stop ImageIcon from tinting an icon with the ambient IconTheme color in Flutter

    (Start Debugging)

  45. How to run dart fix across a whole repo to apply Flutter breaking-change migrations

    (Start Debugging)

    dart fix takes one target directory and it can be the repo root: the analyzer opens a context per nested pubspec.yaml and migrates every package in one pass.

    (Start Debugging)

    Cursor's Self-Hosted Machines, shipped September 2, 2026, move Cloud Agent tool calls onto hardware you own while inference stays in Cursor's cloud.

  47. Fix: MissingMethodException 'AbstractionsStrings.ArgumentIsEmpty' after upgrading EF Core Tools

  48. How to keep appFlavor populated after a hot restart when using flutter attach

    (Start Debugging)

    flutter attach has no --flavor option, so the resident compiler it spawns never defines FLUTTER_APP_FLAVOR and the appFlavor const collapses to null on the first hot restart.

  49. How to find the async void handlers causing ANRs in a .NET MAUI Android app

    (Start Debugging)

    Play Console tells you your ANR rate is over 0.47% and hands you a native stack full of libcoreclr.so frames.

  50. How to consume an RFC 9457 ProblemDetails response from a typed HttpClient without referencing ASP.NET Core

    (Start Debugging)

    The BCL has no ProblemDetails type, and adding a FrameworkReference to Microsoft.AspNetCore.App makes your client refuse to start on a runtime-only container.
