BO that support synchronous and ansynchronous factory methods

[bashinamwila]

I want BO's to support both synchronous and asynchronous static factory methods.
But if I include both versions of the Data Portal methods(one for sync and one for async) I am getting a Data Portal Exception.
For example
[Create] public void Create(){} and
[Create] public async Task CreateAsync(){}
Many thanks

I think you misunderstand how the data portal works, as I don't think there is any reason to do what you are describing.

The client-side data portal is where you invoke the data portal:

  var obj1 = DataPortal.Create<MyBusinessType>();
  var obj2 = await DataPortal.CreateAsync<MyBusinessType>();

The server-side data portal is where you implement data portal operation methods. Whether a data portal operation is implemented as an async method depends entirely on whether your method needs to invoke an async API to create/fetch/update the data.

  [Create]
  private void Create()
  {
    // create the object without calling any async APIs
  }

or

  [Create]
  private Task CreateAsync()
  {
    // create the object by calling async APIs
  }

It doesn't matter whether your client-side calls are sync or async, that depends on how you want your UI to work.

The data portal takes either type of client-side call, relays it to the app server, and invokes the server-side data portal operation method.
