In C++/CLI is there any way to do the following? (I think answer is no because of no Action support?)
public ref class MyClass {
public:
void TaskMethod();
void Start();
}
void MyClass::Start() {
Task^ myTask = Task::Factory->StartNew(??TaskMethod??);
}

Calling StartNew is functionally equivalent to creating a Task using one of its constructors and then calling Start to schedule it for execution. Starting with the .NET Framework 4.5, you can use the Task.Run (Action, CancellationToken) method as a quick way to call StartNew (Action, CancellationToken) with default parameters.
(I think answer is no because of no Action support?) public ref class MyClass { public: void TaskMethod (); void Start (); } void MyClass::Start () { Task^ myTask = Task::Factory->StartNew (??TaskMethod??); } Show activity on this post. Action is just a delegate, which is fully supported in C++/CLI.
If we ever engage in a discussion about task-based asynchronous programming in C#, almost certainly we are going to see some examples using either Task.Run or Task.Factory.StartNew. They are the most widely used ways for initiating a task asynchronously, in most cases in a similar fashion.
Starting with the .NET Framework 4.5, you can use the Run method with an Action object as a quick way to call StartNew with default parameters. For more information and code examples, see Task.Run vs Task.Factory.StartNew in the Parallel Programming with .NET blog. Creates and starts a task for the specified action delegate and cancellation token.
Action is just a delegate, which is fully supported in C++/CLI. (You might be getting it confused with lambdas, which do not have support in C++/CLI.)
Here's the syntax to create a delegate in C++/CLI.
Task^ myTask = Task::Factory->StartNew(gcnew Action(this, &MyClass::TaskMethod));
// For non-static methods, specify the object. ^^^^
// Use the C++-style reference to a class method. ^^^^^^^^^^^^^^^^^^^^
