Message:

#2924:

  • added IEnumerable<T> GetInstances<T>(params object[] args) where T: class and IEnumerable<object> GetInstances(Type type, params object[] args) method to IApplicationManager and implemented them in LightweightApplicationManager -> to instantiate types with specific constructor arguments
  • added RunnerState State { get; } property in IRunnerHost, was already in RunnerHost
  • added user authentication for NativeRunnerHost
  • added optional check for a running docker daemon and available image for type DockerRunnerHost + Exception DockerException
  • added caching of the saved IApplication in ApplicationRunner to prevent a new instance every get call
  • removed System.ServiceModel.Primitives NuGet package
  • lots of formatting
