The problem I’m having is that I am trying to implement a SignalR with CORS from one ASP.NET (localhost:50000) project called Frontend to another ASP.NET MVC project (in the same solution) (localhost:60000).
When I run the application I get this error message in the console:
The following errors occurred while attempting to load the app.
– No assembly found containing an OwinStartupAttribute.
– No assembly found containing a Startup or [AssemblyName].Startup class. To disable OWIN startup discovery, add the appSetting
owin:AutomaticAppStartup with a value of “false” in your web.config.
To specify the OWIN startup Assembly, Class, or Method, add the
appSetting owin:AppStartup with the fully qualified startup class or
configuration method name in your web.config.
When I add a OWIN Startup class I don’t get this error message:
HTTP Error 404.0 – Not Found The resource you are looking for has been
removed, had its name changed, or is temporarily unavailable.
And I guess it’s because it is trying to find the hubs in it’s own project.
Do I need a startup on my Frontend?
Question 2 (if Question 1 == yes):
Must I in the Startup map SignalR to my Backend?
