Issue Running Project Tracker Blazor Sample

[fundez]

Question
I feel stupid for having to ask this, I'm sure I'm missing something simple.

When I run the ProjectTracker.Ui.Blazor.Client project it shows a Fetch:Error and when I run the ProjectTracker.Ui.Blazor.Server project I get the error below. I'm guessing I just missed a setting somewhere.

I'm using Visual Studio 2019 and CSLA.Blazor 5.10-R20012001.

An unhandled exception occurred while processing the request.
SocketException: No connection could be made because the target machine actively refused it.
System.Net.Http.ConnectHelper.ConnectAsync(string host, int port, CancellationToken cancellationToken)

HttpRequestException: No connection could be made because the target machine actively refused it.
Csla.DataPortalClient.HttpProxy.Fetch(Type objectType, object criteria, DataPortalContext context, bool isSync)

I suspect that the app server isn't running.

You need to launch not just the Blazor client, but also the app server project, just like you would with the WinForms or WPF apps.

Right-click on the solution, choose to start up multiple projects, and make sure the Blazor client app is started (without debugging) and the app server project is start (with or without debugging as you choose).

That was it. I knew it was something stupid.

Thanks for your help.

@rockfordlhotka , could we add your instructions to 'How to run' in the solution so that everyone would download it in the future?
thanks

Good idea @Chicagoan2016 - should be in a readme.md in the root of the ProjectTracker directory.
