Azure App Service hosting internal technology - azure

When I host a .NET Core application in Azure App Service, it takes a web.config custom headers configuration, same as in IIS.
Which technology is used in the Azure App Service to host a .NET Core web application?

Thank you Lex Li for your suggestion posting it as answer to help other community members .
"Azure app service is just a name.
you can either host your web app on Windows (IIS) or Linux or on Docker, as you said web.config takes effect, you were using the Windows based App Service hosting plan."
According to that when we host our application in Azure app service there will be no change in our application .

Migration of On-Prem to Azure

I have a web application that is running on my localhost and i want to use azure app service or azure vm to launch it online. which is the best choice?
Solution to host webapplication
There are ways to deploy your application to Azure Cloud.
Method 1 : Azure App Service is fully managed platform for deploying application and scaling apps. it has built-in web hosting feature and supports multiple languages and frameworks.
Please follow the steps to deploy application to App Service.
1.Create sample web application using Visual Studio application.
Create a new project
Right click on created application and choose Publish
Note: Before publish application to Azure, login to visual studio with Azure Account.
Select target-Azure Cloud.
5.Select target platform windows or Linux.
Click on App Service (Windows) > Create new (window)" in App Service (Windows) >Create new.
Select your subscription, resource group & hosting plan.
Check the Application deployment status in visual studio account.
9.Test the application with Azure App service URL once deploy the application to Azure app service.
Go to Azure Portal > Azure App Service > overview > Url.
Application working with App service Url
Method 2: Azure VM
To deploy an application in an Azure VM with IIS, you can follow below steps:
Create an Azure VM with required configuration such as the operating system and size.
Azure Portal > Create > Select Server OS.
2.Use RDP to connect to the Azure VM.
You can use FTP to upload your code to the Azure VM.
Now, open the IIS Manager and create a new website in that IIS.
After that, you can configure the website to point to the location of your application code on the VM.
Finally, test your application.

Uploading Web API to Azure makes Blazor Web App not accessible

I have been trying to understand what I am doing wrong for about a week now. Here is my structure:
I am publishing Blazor server app to number 1. Then I have created ASP.Net Web API, tested it on my localhost and would like to upload it to Azure to access it online. However after I am hitting Publish in Visual Studio, my entire Blazor app is not any longer accessible from https address. Then I am Publishing my Blazor app again from Visual Studio and it is working fine again. What I am doing wrong? Is there any guide how to publish Blazor Web App and then host ASP.Net Web API on the same Azure account?
"on the same Azure account" is of course possible, but when you have 2 projects you will need 2 App Services, maybe under 1 service plan.
Two services cannot share the same URL.
I don't think you need an "API Management service" but I could be wrong.

How to change the URL of Web API service

An Azure App Service Web API using .NET Core was successfully deployed using the Visual Studio 2017 Publish function but now the URL needs to change. How can I do that?
You could map custom DNS name to Azure App Service
Go to the App Service blade.
On the blade, find the Custom domains or bind the SSL settings.
Then you could follow the Tutorial: Map an existing custom DNS name to Azure App Service and the Tutorial: Bind an existing custom SSL certificate to Azure App Service.
As both API Apps and Web Apps share the same underlying infrastructure.
Hope it helps.

Blazorhosted ASP.NET Core 3 as Azure App Service

Should hosting a Blazor netcore 3.0 ASP.NET app through Azure App Services be working? I just set up the sample app using preview3 blazorhosted template which works fine locally, but it's not working as an Azure app service. Has anyone tried this on the new core3 templates?
You can do it, you need to install .NET Core 3.0 on your web app in Azure, check extensions, install preview and restart the app.

Web API app with OWIN 'SystemWeb' on Azure App Service

I am creating app which uses Identity 2.1.0 framework in .NET. I started project in Visual Studio 2015 as Empty Web App (template). Now, I use Microsoft.AspNet.WebApi.Owin, and also Microsoft.Owin.Host.SystemWeb NuGet packages in my project. I understand that OWIN is a specification made to avoid monolithic frameworks and to specify how smaller application components interact with servers. However, I have requirement to deploy to Azure App Services.
I have found examples (blogs) where people deploy OWIN Web Api app as self-hosted to the Azure Cloud Services worker role. But I don't want this, as I don't use Cloud Service.
Since I am using Microsoft.Owin.Host.SystemWeb, am I going to be able to deploy this to Azure App service (which I assume manages internal IIS instance) ?
.NET ecosystem newbie here - so please excuse me for any possible redundancies in the question.
Microsoft.Owin.Host.SystemWeb is designed for hosting in IIS and all Azure App Service web apps are hosted in IIS, so this is exactly what you want (In fact, self-hosting likely won't work with Azure App Service).
