 # Copilot Instructions

 ## Project Guidelines
- All new byte[xx] calls should use using var data = ArrayPool<byte>.Shared.Lease(xx); instead of directly allocating byte arrays
+- When running tests in this workspace, do not run tests for the net48 target framework.
+- When changing System.Text.Json code in this workspace, verify API availability for netstandard2.0 and netstandard2.1 instead of assuming newer APIs exist.

+# Multi .NET Framework Targeting
+
+## Instructions
+- The main project "WireMock.Net.Minimal" targets `netstandard2.0` and `net8.0`. Ensure that any new code or dependencies are compatible with these frameworks.
+
+
+# C# Guidelines
+
+## Instructions
+- When a new ByteArray is needed, do not use `var data = new byte[bufferSize];`. Always use `var data = ArrayPool<byte>.Shared.Lease(bufferSize);`.

m4tchl0ck	f919929cb7	Add injectable IScenarioStateStore for distributed scenario state (#1430 ) * Move ScenarioState to Abstractions and add IScenarioStateStore interface ScenarioState is moved to the Abstractions project so it can be referenced by the new IScenarioStateStore interface. The interface defines the contract for storing and retrieving scenario states, enabling distributed implementations. * Add InMemoryScenarioStateStore default implementation Wraps ConcurrentDictionary with OrdinalIgnoreCase comparer, preserving exact current behavior. The Update method encapsulates read-modify-write so distributed implementations can make it atomic. * Wire IScenarioStateStore into middleware options, settings, and consumers Replace direct ConcurrentDictionary<string, ScenarioState> usage with IScenarioStateStore across all consumer files. The store is injectable via WireMockServerSettings.ScenarioStateStore, defaulting to the InMemoryScenarioStateStore for backward compatibility. * Add FileBasedScenarioStateStore for persistent scenario state In-memory ConcurrentDictionary backed by JSON file persistence in __admin/scenarios/. Reads from cache, mutations write through to disk. Constructor loads existing state from disk on startup. * Make ScenarioStateStore non-nullable with default InMemoryScenarioStateStore Move InMemoryScenarioStateStore from WireMock.Net.Minimal to WireMock.Net.Shared so it lives alongside WireMockServerSettings. This allows WireMockServerSettings.ScenarioStateStore to be non-nullable with a default value, following the same pattern as DefaultJsonSerializer. The null-coalescing fallback in WireMockMiddlewareOptionsHelper is no longer needed.	2026-03-25 13:04:44 +01:00
