- Move all channel-related types into `Stack/Opc.Ua.Core/Stack/Client/Channels/`
subfolder (#13).
- Un-obsolete `SessionReconnectHandler` and the SessionExtensions
`ReconnectAsync(connection, ct)` / `(channel, ct)` extensions; remove
all SRH-related `#pragma warning disable CS0618` suppressions from
applications and tests. AttachChannel/DetachChannel remain obsolete (#1, #4).
- Remove the shared-budget section from MigrationGuide.md (#3).
- Mark `ManagedSession.AttachChannel`/`DetachChannel` `[Obsolete]` so the
warning surfaces all the way up the supported API surface (#9).
- Break the `<see cref=…>` line in `Session.ChannelManager.cs` to stay under
140 chars (#10).
- Move `ChannelManagerSessionFactory` from `Opc.Ua.Gds.Client.Common` into
`Opc.Ua.Client` as a public, documented session-factory option (#11).
- Audit other client classes for `IClientChannelManager`-aware overloads;
add `ISessionFactory`-accepting overloads on `GlobalDiscoveryServerClient`,
`LocalDiscoveryServerClient`, `ServerPushConfigurationClient` so any
session factory (including `ChannelManagerSessionFactory`) works (#12).
- Refactor MCP server (`OpcUaSessionManager`, `Program`) to use
`ManagedSession` + DI-resolved `IClientChannelManager`; remove
`SessionReconnectHandler` and manual keep-alive reconnect (#2).
- ConnectionStateMachine code-style fixes: use named delegate types,
collapse multi-line callback properties to single lines, swap
`timeProvider`/`maxTotalReconnectTime` constructor param order,
fix multi-line declaration (#6, #7, #8).
- HTTPS resilience: confirmed `Microsoft.Extensions.Http` and
`Microsoft.Extensions.Http.Resilience` 10.6.0 support
`net472`/`net48`/`netstandard2.1`; removed `#if NET8_0_OR_GREATER`
gating from `ManagedSessionBuilder` and `OpcUaClientBuilderExtensions`
and HTTPS csproj package refs (#5).
Verification:
- `Opc.Ua.Client` + `Opc.Ua.Core` + `Opc.Ua.Gds.Client.Common` build
clean (0 warnings, 0 errors).
- 56/56 core channel-manager / retry-budget / HTTPS factory tests pass.
- 129/129 client (ManagedSession + legacy SRH back-compat + SessionExtensions)
tests pass.
