Hi George, There are 3 key things you need to do.

1. Host the Web APIs on its own IIS Website that is separate from the IIS Website that hosts the client app.  IIS allows you to create multiple websites in a single server.  Here are instructions to setup the Web APIs on its own dedicated website and how to properly compile the Web APIs for such deployments: https://docs.appeon.com/ps2021/Hosting_Web_APIs_in_IIS.html

2. Since you have more than one app, save each app’s Web API files is in its own subfolder in IIS.  This means each app in PB IDE on Web API tab config should have a URL like https://www.company.com:port/app1, app2, etc.  Or you can adjust the URL after compilation by following these instructions: https://docs.appeon.com/ps2021/Change_Web_API_URL.html

3. Lastly, make sure the port # you set in IIS for the Web APIs is not being used by some other process and that the firewall allows HTTP traffic to that port #.

Hi George;

  You only need to deploy the CAL once unless, you change PB versions or apply an MR (aka new build).

  If you created the 2nd App's Cloud app project by copying the 1st Apps project. Then make sure on the General Tab & the Web API tab that you specified a different App Name & a different C# deployment (repository) name.

  Also, make sure that your App deployment names have no spaces or periods in the name.

Hi Armeen and Chris,

Thank you a lot for your replies. I looked through all the help file opened by Armeen's 1st link. As far as I understood, it doesn't relate to the deployment on localhost and my local IIS.

Then, according issues 2 in Armeen's comment, I tried to change Web API URL on Web APIs Tab of PowerServer Project from default (localhost:5000) that I used for my 1st app to localhost:84/cpms_pr (1st screenshot in the attached file). Unfortunately, compiling and running Web APIs after this gave error (2nd screenshot). Everything is OK relating the 3rd issue in the Armeen's comment.

I checked everything, according Chris' recommendations, and everything looks fine. I confirm that CAL created for the 2nd app works fine with the 1st one. However, when I tried to use Web APIs of the 1st app for the 2nd one, I got error (3rd screenshot). And when I republished Web API for 2nd app to a new separate folder, copied all the folders and files in it to new web_api folder in wwwroot, and created new web_api site with port 84 (web_apis for the 1st app has port 82), I got the error again (4th screenshot). http://localhost:84/health gives "HTTP Error 500.32 - Failed to load .NET Core host." http://localhost:82/health, at the same time, returns "Unhealthy" message as it should. And finally, "dotnet CustomizaDeploy.dll -url" command shows correct urls for both application.

Do you have any other suggestions? I would be very appreciated,

George

Dear Armin, Chris and Logan,

Thanks to Logan Louie's suggestion, I solved my problem and I can run both applications in my development environment without problems.

I am very grateful to all of you for your suggestions and for your willingness to help me. You are truly a great team!

George
