C# Plugin System

• For a new project, add a reference to the PluginBase project
• Ensure project XML includes

<ItemGroup>
      <ProjectReference Include="path\to\PluginBase.csproj">
          <Private>false</Private>
          <ExcludeAssets>runtime</ExcludeAssets>
      </ProjectReference>
  </ItemGroup>

• Create a new class (or classes) which implements IPlugin

• OnLoad is called as soon as the plugin is instantiated.
• CreateTask may be called at any time after OnLoad and before OnUnload. The returned task should implement the desired behaviour of the plugin. CreateTask may return a PluginResultData object or null.
• OnUnload may be called at any time after OnLoad. Note that it may be called before CreateTask, whilst a task is still running or after it has completed.

--help for in-tool help

--pluginLocations - List of locations to load plugins from, can be a filepath or URI - see "Loading remote plugins" below

--targetPlugins - List of plugin names to run. If not provided all plugins are run.

--pluginLocationsFile - List of files from which to load plugin paths. May be local or remote files. Each path should be on a new line.

The PluginHandler will accept remote URIs for plugins. The URI must contain the name of the assembly as the last part of the path. eg. https://example.com/PluginName.dll or https://example.com/SearchPlugin.dll?token=abc123or https://example.com/QuestionPlugin?token=abc123.

Loosely based on the .NET Core plugin system described here
