How to publish Blazor Web assembly with ASP.NET core hosting and identity auth app to azure App Service?

I want to host a Blazor Web assembly app with ASP.NET core hosting and the inbuilt identity authentication. I am a complete beginner and this is my first post so I apologize in advance for providing irrelevant or insufficient information. Please request additional information.

I created a so-called File -> New -> Project Blazor Web Assembly App with the ASP.NEC Core Hosted Checkbox Checked and selected Individual User Accounts under authentication and created the project. Started the app without debugging went to the registered age and registered and added migration from the browser button. Logged in and it worked fine.

Then I right-clicked on the server project and selected publish and followed the steps to publish on azure. It published successfully. But when I open the browser it gave me an error page "HTTP Error 500.30 - ANCM In-Process Start Failure". Ran the app on the command line. It threw an error:

Thereafter I published to a folder and run the .Server.exe file as administrator and got the exact same error.

This worked fine when Started within the Visual Studio IDE on both IIS Express and Kestrel.

What am I doing wrong?

Thanks in advance.

Solution

  • Since, you have not added your code here. I would suggest you to validate below settings to get this working:

    Add the following settings into appsettings.json, within the "IdentityServer" brackets. This followed the "Clients" element:

    For File:

    "IdentityServer": {
    "Key": {
      "Type": "File",
      "FilePath": "C:\cert.pfx",
      "Password": "password123"
    }
  }

    For Development (don't use in production obviously):

    "IdentityServer": {
    "Key": {
      "Type": "Development"
    }
  }

    For Store:

    "IdentityServer": {
  "Key": {
    "Type": "Store",
    "StoreName": "My",
    "StoreLocation": "CurrentUser",
    "Name": "CN=**WHATEVER NAME YOU USED AS THE DISTINGUISHED SUBJECT FOR YOUR CERT**"
  }
}
