I am new to Azure.
I was able to use the Microsoft bot Composer to publish my first chatbot to the azure window web service. I also log into the azure portal to use the edge browser to open up KuDu Console.
I also open up the corresponding shell. I can use the shell (such as the cmd or powershell) to trace the nested wwwroot. But, the nested wwwroot is hidden from the kudu console? Why the azure window web service wants to keep the nested wwwroot hidden from the KuDu console? In anther word, the kudu console only displays the top-level wwwroot while keeping the sub-level wwwroot hidden from being discovered.
If I have understood you correctly, It's due to the sandbox restrictions.
All Azure Web Apps run in a secure environment called a sandbox. Each app runs inside its own sandbox, isolating its execution from other instances on the same machine as well as providing an additional degree of security and privacy which would otherwise not be available.
The sandbox generally aims to restrict access to shared components of Windows.
Applications are highly restricted in terms of their access of the file system.
I suggest you to check these docs for more information on this:

I have a .Net core app developed using Visual Studio 2019 and deployed on Azure app service. I have function app as well in the same solution. I have to do couple of things and then redeploy to Azure app service.
Add one .cshtml file
Modify one .cshtml file
My question is, how to deploy the CSHTML file only to the Azure app service? Without affecting the existing functionality of application.
As per my understanding, if web app is deployed in Azure app service then the whole thing (solution) has to be deployed even though there are/is very small code modifications.
Please let me know.Thanks.
Even if you have Web App and Function App in the same solution, they should be separated units of deployment. That said, your deployment pipeline should be separately triggered for Web App and Function App.
From the technical point of view(or architecture) there's no concept of "solution". Solution(.sln) is a Visual Studio specific being and even though it's supported e.g. in VS Code, I'd never treat it as deployment unit. Especially in your scenario, when in fact two separate services are responsible for handling your code.
Even if you deploy Function App as a part of the same App Service Plan as your Web App, it's still a separate Azure service. In such a scenario they only share compute.
Yes its possible if you have access to kudu deployment center you can perform manual add/update information , please visit below URL:-
https://[yourAppName].scm.azurewebsites.net
You can also navigate to this site using the azure portal , once you open the app service blade you will find the kudu deployment center option in the bottom left of the menu.
It will provide an online file explorer of your application hosted on the app service and from there you can migrate to relevant folder and perform add/update.
Can I host a web application created on .net core 2.1 with sql server as database to azure web app service using CI tools / MS WebDeploy?
The following points I want to take care:
The application is using file system for temp storage and file storage
Deployment should be managed by some CI tools such as jenkins
After deployment, the app settings file should be modified with some keys/server details
Log files(stored on app root) should be accessible by application administrator
Is there a way to create a virtual directory same as in IIS and upload the files using FTP or similar protocols..?
All your doubts about deploying .net core 2.1 web app are achievable.
Suppose our projects are all completed and uploaded to github.
Questions and explanations about your concerns：
About the connection configuration using the database, you can directly configure it in web.config. If you are using azure sql server, find the connection string, set up the firewall, and pass the SSMS test, you can test the connection in the code. It can also be added in the Configuration -> Application settings -> Connection strings in the portal. After the addition, the priority is higher than the configuration in web.config, which will override the configuration and not modify the web.config file.
Regarding the use of file storage, you can use azure storage services or not. Looking specifically at the business, for example, very small pictures, documents and other files can be stored in the current program running directory, which is consistent with the original development at the code level. When publishing, you need to include the MyFiles file in the publishing process, or wait for the publishing to be completed and add folders manually in kudu, or the program can judge. It is recommended to use the program to judge that the subsequent program upgrade will not lose data.
The confidential information in the app settings file can actually be configured in web.config or appsetting.json. Make sure that the offline project is running properly when you are debugging locally, and then you can publish it. The rest is configured in the portal as in the first explanation.
The Log Files file storage can fully achieve the effect you want. It should be enough to set the owner permissions of this app services. For details, please refer to the official documentation.
Virtual directories and virtual applications, I have a better answer in another post here, you can refer to it.
Steps：
First of all, we can create a web app in portal and select .net core 2.1. Create appservices, and click Deployment Center when finished.
Follow the prompts step by step, and wait until the Action in github is completed, and the release is successful.
I would like to run ILSpy on one of my DLLs to verify code is running on a deployment slot and unable to figure out how to retrieve the DLLs from my PaaS WebApp.
As all mentioned above, If we want to get the published files from the Azure WebApp, we could use the Kudu tool to do that easily.
More info about Azure website file structure, we could refer to this document. If you want to know more about Azure WebApp, you could refer to Azure WebApp Sandbox.
I created an app service at http://testsam.controltrackonline.com, it loads properly. I have also created a folder within it called webapi but it does not load up and does not allow publishing content to it via appVeyor. The non loading folder location can be loaded here http://testsam.controltrackonline.com/webapi
I do not see any permissions issues surrounding this as other app services with same settings load well with folder within. But for this appservice there seems to an issue.
Any ideas?
It seems that you'd like to publish content to an Azure web app virtual directory, so please make sure you configure virtual directory or application under Application settings blade in the Azure Portal.
Note: you can also refer to "Deploying multiple virtual directories to a single Azure Website" to set up the virtual directory or application.
I have also created a folder within it called webapi but it does not load up and does not allow publishing content to it via appVeyor.
I do not see any permissions issues surrounding this as other app services with same settings load well with folder within. But for this appservice there seems to an issue.
Please try to use FTP or Kudu to access your Azure web site folder, and then you can try to upload your content package to webapi folder and check if it works as expected.
Besides, If issue only appear on that specific app service, you can create an Azure support request, Azure support can help you investigate the issue.
I'd like to execute a
appcmd set config /commit:WEBROOT /section:sessionState /mode:StateServer /stateConnectionString: tcpip=loopback:42424 /stateNetworkTimeout: 120 /useHostingIdentity:True
command on the box belonging to an Azure Web App. The console is a "sandbox environment", so I don't necessarily expect to have enough privileges, but appcmd is not recognized as a command.
Same thing happened with the KUDU special console - which looked more promising in terms of potential privileges to carry out the task -, both with the CMD and the PowerShell console.
My main goal is to start the IIS's State Server. How to start ASP.Net State Service in Azure mentions "startup task", but I couldn't figure out how to do that. https://technet.microsoft.com/en-us/library/cc732412(v=ws.10).aspx quotes appcmd.
Per your link in your question: Startup tasks are for web/worker roles in Cloud Services, not Web Apps (completely different things; web/worker role instances are Windows Server instances, not a sandboxed environment).
You cannot enable IIS State Server on Web Apps. You'll need to store your session state in something like Redis Cache service, which runs independent of Azure Web Apps. Really, you can use any cache (or storage) you want that's external to the Web App sandbox, as long as you have proper drivers/providers for what you choose.
