Introduce GetFullyQualifiedPocoName in CsHelpers class to return fully qualified POCO names. Update using directives to include AXSharp.Compiler.Cs.Helpers. Refactor Create methods in various builder classes to use GetFullyQualifiedPocoName. Update AddToSource method calls to use fully qualified POCO names. Modify CsPlainConstructorBuilder and CsPlainSourceBuilder to use GetFullyQualifiedPocoName. Wrap generated code in Pocos namespace in CsPlainSourceBuilder. Update AddCreatePocoMethod in CsOnlinerSourceBuilder to use GetFullyQualifiedPocoName. Adjust namespace and type declaration methods in CsPlainSourceBuilder to use GetFullyQualifiedPocoName.

Updated namespace references for Pocos classes across multiple files to use the global:: prefix. This change affects methods such as OnlineToPlainAsync, _OnlineToPlainNoacAsync, PlainToOnlineAsync, _PlainToOnlineNoacAsync, ShadowToPlainAsync, PlainToShadowAsync, DetectsAnyChangeAsync, and CreateEmptyPoco. The updates ensure the correct global namespace is used, avoiding potential conflicts and improving code maintainability.

Modified AXSharp.Connector.S71500.WebAPITests.csproj to update package references and include new certificates. Replaced WebApiConnector instantiation with TestConnector.TestApiConnector in Exploratory.cs and WebApiConnectorTests.cs. Removed TestConnector class from WebApiPrimitiveTests.cs and added new using directives. Updated GH_PTKu_ix_56.cs, GH_PTKu_ix_59_68.cs, and GH_PTKu_ix_xx.cs to use TestConnector.SecurePlc. Updated apax.yml with new project name, version updates, environment variables, and scripts. Modified go.ps1 to set targetInput and update sld command. Updated Directory.Build.props to target net8.0. Added new TestConnector.cs for handling Web API connections and certificate validation.

Modified OnlinerBaseTypeTests.cs to use Is.InstanceOf for more accurate type checking in GetParentTest. Updated test_L10.ps1 and test_L2.ps1 scripts to run with --framework net9.0 and exit with $LASTEXITCODE for improved build and test processes.

Updated `dotnet run` command to use `--framework net9.0` in
`dev.yml`, `master.yml`, `pr-dev.yml`, and `release.yml` to
ensure the project runs with .NET 9.0. Removed the `Test Report`
step using `dorny/test-reporter@v1` from all mentioned YAML
files, which was generating a test report regardless of the
previous steps' outcomes.

Updated the target framework version from .NET 8.0 to .NET 9.0 in multiple files:
- In `BuildContext.cs`, changed `Framework` property of `DotNetRunSettings` from `"net8.0"` to `"net9.0"`.
- In `AXSharp.templates.csproj`, updated `<TargetFramework>` element from `net8.0` to `net9.0`.
- In `axsharpconsole.app.csproj`, updated `<TargetFramework>` element from `net8.0` to `net9.0`.

Updated `TestCollectionOrderer` attribute namespace in `DisplayNameOrderer.cs`. Removed various `Onliner` type properties and `Parent` and `Interpreter` properties across multiple classes and namespaces. Added methods `GetChildren`, `GetKids`, and `GetValueTags` to return collections of children, elements, and value tags. Updated `units.csproj` to target `net9.0` and updated package references.

Modified BuildContext to update ProcessRunner arguments and added new properties. Updated TestsTask to use >= for TestLevel and replaced AX_WEBAPI_TARGET with AXTARGET. Removed AXSharp-L3-tests.slnf. Added conditional compilation in ApaxTests. Updated TestConnector to use environment variables. Updated apax.yml with new targets, dependencies, and scripts. Enhanced Entry.cs with new methods and environment variables. Updated integrated.csproj to include new certificates. Removed conditional delays in PlainersSwappingTests and GH_ISSUE_183. Added new solution filters for integration and WebAPI tests. Added new certificate files.
