Breaking Change: Change SaveState in Csla.Blazor.State.StateManager from void to Task

[StefanOssendorf]

csla/Source/Csla.Blazor/State/StateManager.cs

Lines 64 to 72 in 4cece89

	public void SaveState()
	{
	var isBrowser = OperatingSystem.IsBrowser();
	if (isBrowser)
	{
	_sessionManager.SendSession();
	}
	}
	}

As shown above the _sessionManager.SendSession() method returns a Task which is currently ignored due to the voidness of the method. I think this should be changed for 9.0 to Task to make it possible to await that.

Agreed. I should have fixed it before releasing CSLA 8.

It was originally void because it was designed to be called in a page's Dispose method, and this was the implementation that worked in that context.

Now that state manager no longer works that way, this should be async.
