Clears all 11 unresolved SonarCloud issues on master. The netstandard2.0 build (#252, #401) caused every one of them.
Fixed in code (9)
CA1510 ×4 in DashboardApiClient / DashboardConsumerClient: if (x == null) throw … becomes _ = x ?? throw …. ArgumentNullException.ThrowIfNull is what the rule suggests, but it doesn't exist on netstandard2.0, which Dashboard.Client targets. A throw expression compiles on every target. Checks run in the same order and throw the same exceptions as before.
S2925 ×5 in IntervalTimerTests / MonotonicTimeTests: Thread.Sleep becomes await Task.Delay. The wait still stands in for a busy caller or for real time passing, so the drift bound (1200ms vs ~1400ms for a drifting timer) still separates a correct timer from a broken one.
Suppressed with a justification (2)
S6588 on Epoch.Unix (Redis): netstandard2.0 has no DateTime.UnixEpoch. The remark on Epoch.Unix also said the field arrived in .NET 5. It has been in the framework since netstandard2.1, and the remark now says so.
S2094 on IsExternalInit: the compiler looks the type up by name and needs it to be empty.
These are [SuppressMessage] attributes in the source, not Won't Fix marks in SonarCloud, so a reviewer can see the reason in the code.
Verification
Dashboard.Client and Transport.Redis build in Release with -p:CI=true on net10.0, net8.0 and netstandard2.0, with 0 warnings.
Dashboard.Client.Tests: 92/92 pass.
The compatibility timer tests pass 14/14, repeated 6 times.
No changelog entry: nothing here changes behaviour a consumer can see.
Null checks in Dashboard.Client use throw expressions, which work on every target including netstandard2.0, where ArgumentNullException.ThrowIfNull does not exist. The compatibility timer tests wait with Task.Delay instead of Thread.Sleep. Epoch and IsExternalInit carry justified suppressions, since netstandard2.0 has no DateTime.UnixEpoch and the compiler needs IsExternalInit to be empty.

📝 Walkthrough
Walkthrough
The diff adds analyzer suppressions for compatibility types, rewrites client constructor null checks, and replaces blocking sleeps with asynchronous delays in compatibility tests.
Changes
Analyzer suppressions
Layer / File(s)
Summary
Compatibility type annotations Source/Compatibility/IsExternalInit.cs, Source/DotNetWorkQueue.Transport.Redis/Basic/Time/Epoch.cs
The types receive analyzer suppressions. The epoch comment identifies netstandard2.1 as the version that introduced DateTime.UnixEpoch.
Constructors use throw expressions or null-coalescing throws for null arguments. The exception types and parameter names remain unchanged.
Asynchronous compatibility test delays
Layer / File(s)
Summary
Asynchronous test delays Source/DotNetWorkQueue.Tests/Compatibility/IntervalTimerTests.cs, Source/DotNetWorkQueue.Tests/Compatibility/MonotonicTimeTests.cs
Tests replace Thread.Sleep with await Task.Delay. Two monotonic time tests change to return Task asynchronously.
The PR contains equivalent validation rewrites, compatibility annotations, and asynchronous test delays without an identified merge-blocking risk.

Pull Request Overview
The PR successfully addresses 11 SonarCloud issues, focusing on modernizing null-check patterns and improving test reliability by replacing blocking sleeps with asynchronous delays. The changes are up to standards according to Codacy analysis. The primary gap identified is the lack of unit tests to verify the newly implemented ArgumentNullException.ThrowIfNull logic in the dashboard client classes.
About this PR
The implementation of CA1510 (throw expressions) in DashboardApiClient and DashboardConsumerClient lacks corresponding unit tests to verify that ArgumentNullException is thrown as expected when null arguments are provided to the constructors.
Test suggestions
Verify that IntervalTimer accuracy and drift detection logic remains correct after switching from Thread.Sleep to Task.Delay.
Verify that MonotonicTime correctly measures elapsed time using asynchronous delays in tests.
Verify that DashboardApiClient constructor throws ArgumentNullException when options or httpClientFactory are null.
Verify that DashboardConsumerClient constructor throws ArgumentNullException when httpClientFactory is null.
Prompt proposal for missing tests
Consider implementing these tests if applicable:
1. Verify that DashboardApiClient constructor throws ArgumentNullException when options or httpClientFactory are null.
2. Verify that DashboardConsumerClient constructor throws ArgumentNullException when httpClientFactory is null.
