Use IIS manager to administrate web app
Before we could use IIS manager to administrate web app.
Remote Administration of Windows Azure Websites using IIS Manager
https://azure.microsoft.com/en-us/blog/remote-administration-of-windows-azure-websites-using-iis-manager/But around year end of 2017, we got error like below.
---------------------------
Internet Information Services (IIS) Manager
---------------------------
Could not load file or assembly 'Microsoft.Web.Configuration.AppHostFileProvider, Version=8.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified.
---------------------------I tried sometimes, but this problem isn't resolved yet.
I hope this problem will be fixed.47 votesThank you for bringing this up. We are aware of the issue that the capability to manage apps through the IIS manager is currently not available since the move of App Service to WS2016.
We don’t have a timeline of when we will be able to complete the work to re-enable, but we will update when there is more to share.
Thanks,

Access-Control-Allow-Credentials not set in credentialed CORS request
Not sure if this is a bug or a feature request. This is affecting me when using Azure Functions, but I beleive this has to do with the CORS implementation in Web Apps.
Basically, the Access-Control-Allow-Credentials header is not being set in response to credentialed requests.
https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Access-Control-Allow-CredentialsSomeone else posted this issue in the azure functions github, but @lindydonna said this was to do with Web Apps. Original github issue is here:
https://github.com/Azure/azure-webjobs-sdk-script/issues/620The problem is also documented on the official MS developer blog here:
https://blogs.msdn.microsoft.com/benjaminperkins/2017/04/12/azure-functions-access-control-allow-credentials-with-cors/38 votesPlacing back as Under Review after discussion here in the comments, over GitHub and internally in the team. We will share more when we have a clear approach and timeline.

DNS resolution is not working in Azure Web App for Containers (linux)
DNS resolution is not working in Web App for Containers (linux) when using custom docker image. The DHCP generated resolv.conf is broken. After using SSH to log in to the container trying nslookup google.com also fails with DNS resolution error.
See my sample project for more details:
https://github.com/henkosch/azure-webapp-dnstest
The problem is also mentioned in the comments section on this page:
https://docs.microsoft.com/en-us/azure/app-service/containers/app-service-linux-faq
Does anyone have an idea how to fix this?

Allow access to certificate stores
As of today, you can't programatically install your own certificates (e.g. read from App_Data and Add(..) to store) to the Root or CertificateAuthority stores. This is seen in the LocalMachine as well as CurrentUser certificate store location. The PaaS responds with a "CryptographicException: Access is denied." which is bizarre because non-basic plan customers are paying for the entire underlying VM. Even on the basic plan you should allow this but restrict it to the CurrentUser store location since the VM/IIS could be shared with other cloud customers.
As of now, you can only access the "My" store which is a…

Enable 'Connect', 'Log Stream', 'Console' etc for App Service Environment
When you deploy an App Service into an App Service Environment behind an ILB, much of the UI is greyed out. Examples of this is the 'Connect' button, 'Log Stream', 'Console' etc.
I have to manually construct a URL to get to the kudu endpoint right now in order to use the console.

allow empty collection as a value of Set-AzureRmWebApp -AppSettings parameter
Attempting to clear AppSettings using
Set-AzureRmWebApp -ResourceGroupName $resourceGroupName -Name $name -AppSettings @{}
fails the validation. I believe this is a bug because it should be possible to clear all AppSettings this way.9 votesWe’re moving this to dev and will update when complete.

Allow us to remove the Zend Extension "opcache" from the default php.ini file
When you run PHP 5.5+ in an Azure website, the opcache Zend Extension is automatically enabled as the first Zend extension in the php.ini file.
"[ExtensionList]
...
zend_extension=php_opcache.dll"Any other Zend extension we add is appended after opcache.
Since this file is read-only, you cannot remove this extension.
This conflicts with other Zend extensions like ioncube, which require themselves to be the first extension loaded.
Please allow us to choose whether the opcache extension is enabled in php.ini OR give us a way to remove it WITHOUT running a custom PHP runtime of our own.
I'd much rather you manage…

"HTTPS Only" Setting Should Be Inherited With Configuration In Deploy Slot
We've set up a custom domain and purchased and installed security certificates. Everything works great for https, and we've switched on HTTPS Only in the Custom domain panel for our production slot.
Then, we created a new build with new features we developed in the latest sprint, created a new deploy slot, checked the box for the deploy slot to inherit its configuration settings from production, and... the HTTPS Only setting is switched to off, regardless of inheriting configuration settings.
We switch HTTPS Only back on in the deploy slot, go through our upload. When we swap the deploy slot…

When we choose the Backup Database from Backup configure after The connection strings is overwritten.There is a bug.That doesn't seen to have problem.

REST API shouldn't return 0 when it doesn't have the actual data
Calling the REST API to get CPU or memory usage of an app service plan, if you ask for it in the last minute it can return 0 to you, when a few minutes later it will return the actual value for the same time, it seems it takes a while for the real data to be available to the API, however I think it's wrong to return incorrect data, it should not return a value until it has the real value.

Enable surfacing all attributes from Win32_PerfRawData_Tcpip_TCP (https://msdn.microsoft.com/en-us/library/aa394341(v=vs.85).aspx)
We have been experiencing sporadic times of high dependency latency. Understanding where this is coming from would help narrow down a long term solution.
