How to debug with 2 web API projects in visual studio solution?

Question

I have a visual studio solution with 2 projects in it. Both are web API's (not .net core). When I had one project I could debug it by hitting

http://localhost:53961/api/...

However I then added the 2nd project. How can I start debugging the second one? It doesn't seem to hit the breakpoint. I get

No HTTP resource was found that matches the request URI

When I put a breakpoint on the main method

    // GET: api/<controller>
    [HttpGet]
    public async Task<Result> Get(string emails)
    {

    }

I see a message:

The breakpoint will currently not be hit. No code has been loaded for this code location.

Have you set the second apis port to a different from the first api? — Marcus Höglund, Jun 04 '18 at 19:36
If you want the api's to run on the same url, you need to make sure to load the assemblies from one api to the other. In .net core you only need to refere the project to the startup project..don't know if it's the same in net45> — Marcus Höglund, Jun 04 '18 at 19:44

You can set "Multiple startup projects". Right click on solution in solution explorer and then click properties. Common Properties->Startup Project and then select "Multiple startup projects" and then set the Action for both of your APIs to "Start"
