When I'm deploying the Service Fabric Application with new version, the complete application is getting replaced with new version in service fabric cluster. And it is working fine as expected in upgrade scenario. But, When I deploy the application with downgraded version, application is not getting replaced rather it is again creating an application with older version.
After the application deployment, I have two different versions of same application in service fabric cluster.
How we can downgrade the application to older version with application deployment. Does we need to change settings/parameters for cluster or in power shell command.
Service Fabric cluster with two versions after deployment of older version image
Thanks.
This is a view of the Service Fabric Image store, which shows the current versions available, below this you should be able to see the actual version that is being used within the cluster, see below, versions 1.0.0 and 1.0.1 are currently in the image store but version 1.0.0 is the version being used.
You can confirm this by looking at your nodes as well.
EDIT:
To remove the unwanted versions from the cluster run the following in PowerShell, obvious replace with your application name and version.
> Unregister-ServiceFabricApplicationType -ApplicationTypeName DowngradeDemoType -ApplicationTypeVersion 1.0.1

I'm using Azure Web Apps and every time I try to make it use node 14.x it resets back to 10.x after every deployment.
When I go to Configuration > General the Stack is blank, I have to select Node and then 14.x to make it work.
Edit: Linux is used not Windows
I managed to solve the problem by adding
runtimeStack: "NODE|14-lts"
in the yaml file, 16.x is not yet supported so it defaults back to 10.x
Add WEBSITE_NODE_DEFAULT_VERSION app setting for the Node version, but make sure the exact version you fill in is installed on the workers (assuming Windows workers here, since you don't specify) -
https://{yourWebAppName}.scm.azurewebsites.net/api/diagnostics/runtime
That's the Kudu API route returning runtime versions. Pick the latest installed Node version from there.
Your app setting becomes
WEBSITE_NODE_DEFAULT_VERSION = 14.16.0
As long as you don't remove or overwrite this app setting, your Node version will stay consistent across code deployments.
Tracking a GitHub issue here since the documentation page is confusing about the version values -

We build our web app with Azure DevOps pipelines and deploy into Azure with an Azure DevOps release. I think today netcore got updated to netcore 3.1.4 on our build agent. But now our Azure DevOps deployment fails, because the netcore 3.1.4 runtime is not yet installed on our app service in Azure.
The error message we are getting:
Could not find 'aspnetcorev2_inprocess.dll'. Exception message:
It was not possible to find any compatible framework version
The framework 'Microsoft.AspNetCore.App', version '3.1.4' was not found.
- The following frameworks were found:
2.2.8 at [D:\Program Files\dotnet\shared\Microsoft.AspNetCore.App]
3.0.3 at [D:\Program Files\dotnet\shared\Microsoft.AspNetCore.App]
3.1.1 at [D:\Program Files\dotnet\shared\Microsoft.AspNetCore.App]
3.1.3 at [D:\Program Files\dotnet\shared\Microsoft.AspNetCore.App]
You can resolve the problem by installing the specified framework and/or SDK.
This makes sense and can happen, but what is the best way to go about fixing this?
I could fix my build to a specific netcore version. But I don't like this, because we do want to keep updating to newer versions, but we don't want a version that is not available in Azure app service.
Am I correct in thinking that we would have to install our services self contained, because otherwise we could get into this issue more often when Azure DevOps is faster with installing patches than Azure?
Or is there a way to force update Azure app service to the new netcore 3.1.4 security patch which would be ideal I think?
I just need some guidance in what is the best approach to fix this issue?
Or is there a way to force update Azure app service to the new netcore 3.1.4 security patch which would be ideal I think?
AFAIK, there is no such a way to force update Azure app service to the new netcore 3.1.4.
We could keep track on the latest releases on the https://aspnetcoreon.azurewebsites.net/, but we could not update it at this moment.
To resolve this issue, we recommend that you publish your app as self-contained produces an application, which includes the .NET Core runtime and libraries, and your application and its dependencies. Users of the application can run it on a machine that doesn't have the .NET Core runtime installed.
Publishing your app as self-contained produces a platform-specific executable. The output publishing folder contains all components of the app, including the .NET Core libraries and target runtime. The app is isolated from other .NET Core apps and doesn't use a locally installed shared runtime. The user of your app isn't required to download and install .NET Core.
You could check this document .NET Core application publishing overview for some more details.
Hope this helps.
If you want version of netcore to be automatically updated as an updated version is available, building our service as self-container seems like a good option: no need to have anything installed on the machine running (ie the version on Azure DevOps and Azure Web App don't have to match).
The main downside of this approach is that the build is going to less deterministic: running your build twice with on the same commit might create different binaries depending on what is currently install on the build agent. if you want to know more, here is an interesting post arguing about why deterministic build is important.
To keep the build determinitic, you can use the Use .Net Core task at the beginning of the build (that will make sure that the desired version of the dotnet sdk is on the agent). You could also add a global.json in your repository to lock for both the build on your dev box and in Azure Dev Ops.
This is a common topic of discussion, and you can find a lot of blogs advocating one or another side.
There were big discussions started when Microsoft released LTS net core 3.1 and it took some time before Azure start supporting the 3.1 runtime as well.
You could find a lot of blogs strongly suggesting to deploy your web apps as self-contained (runtime is ~100MB in size) and cut loose the dependency towards Microsoft supporting the latest runtime. While others advocate that the applications should remain as light weight as possible and the runtime should be set in the pipeline. But that is still up on you. I, myself prefer to deploy self-contained apps after my bad experience with net-core 3.1.
There is no established best practice.
In the past , I've run into the same situation, you can fix this by manually setting the value from RunTime Stack drop down. If you manually update the build processes .yml file
RuntimeStack: 'DOTNETCORE|3.1'
I'm migrating from VS2015 to VS2017, and updating a repo's solutions to be able to be compatible with VS2017. In the process, I'm also updating the Azure SDK version from 2.7 to 3.0.
I'm setting up a fresh dev environment, and installed Azure SDK 3.0 via VS2017's Azure development workload.
When I opened the solution file in the repo, I got one notice per cloud service project that its Microsoft Azure Tools version was getting upgraded from 2.7 to 2.9...
...and the ProductVersion tag in the corresponding .csproj files was updated from 2.7 to 2.9.
Questions:
Why wasn't this updated to 3.0?
Is there anyway for me to update it
to 3.0 without manually editing the csproj file? I don't see an
option to do so in Properties when I right click the cloud service
projects in Solution Explorer.
Is there some reason I shouldn't be
doing this?
"Microsoft Azure Tools - v2.9" mentioned in your screenshot is just a little misleading.
Underlying reason is that Microsoft hasn't really changed the version number of most components as part of 3.0 SDK release. Even the binaries get installed in the same folder as 2.9.
Good news is that you don't need to do anything special apart from converting the project to target latest version, which you're already getting prompted for.
So once you do convert your project as per the prompt, you're essentially working with SDK 3.0, even though version string says v2.9, because as the links explain, most of the components haven't changed major version number as part of SDK 3.0 version (when comparing with 2.9)
Here are some of the links which talk about this -
Azure SDK for .NET 3.0 Release Summary
No breaking changes to the Azure SDK 3.0 have been introduced in this
release. There is also no upgrade process needed to leverage this SDK
with existing Cloud Service projects. To allow use of the Azure SDK
3.0 without requiring an upgrade process, Azure SDK 3.0 installs to the same directories as Azure SDK 2.9. Most the components did not
change the major version from 2.9 but instead just updated the build
number.
Visual Studio 2017 latest installer does not install Azure SDK 3.0

Azure 3.0 SDK Install Weirdness
An independent blog talking about the same issue.
I am stuck on creating azure batch pool with .net 4.6.1.
I went through those very good resources:
Compute Node - Install .NET 4.6.1
How to get the Windows 2016 Preview OS
and I found out that there is a way to use .net 4.6.1 without installing it manually on a node. There is a programmatic way to set up Windows Ghost image with the latest .net version which is .net 4.6.1 but my node is defined in advance.
I need to have .net 4.6.1 because we use Data Factory and custom activities which are run on azure batch nodes. We upgraded .net version manually on that node but Microsoft doesn't guarantee that the state will preserve and we noticed a few times that node was reset to its original state.
My questions are:
do you know if there is any way on azure portal to choose OS family set to Windows Server 2016 with installed .net 4.6.1 version already?
does anybody know when there will be any os with .net 4.6.1 available?
or should I go with StartTask feature and try to install .net 4.6.1 manually? However, that option sounds like some workaround and not the correct solution.
There is not. They have said that when server 2016 releases on azure, it will be available on batch. Until then, the 4.6.1 install as a startup task is your only option. They also will, at some point, allow us to use custom images, rather than their pre-made images.
Updated 2016-02-07:
You can now deploy OS Family 5 under Cloud Services Configuration in Azure Batch, which is equivalent to Windows Server 2016 (as Marketplace/VM image).
Previous answer:
Answers to your questions:
do you know if there is any way on azure portal to choose OS family set to Windows Server 2016 with installed .net 4.6.1 version already?
Yes, you can change the "Image Type" to Marketplace and select 2016-Datacenter which is Windows Server 2016.
does anybody know when there will be any os with .net 4.6.1 available?
As per above, it's available now for Marketplace (IaaS) under 2016-Datacenter. The Batch team is currently working to support OS Family 5 as a guest OS for Cloud Services.
or should I go with StartTask feature and try to install .net 4.6.1 manually? However, that option sounds like some workaround and not the correct solution.
You can always install it as part of a start task and is considered the proper solution for Azure Batch proper for compute nodes with Windows Server < 2016.
You will still have to use the StartTask to install .NET 4.6.1. In the first resource you mentioned, there's a small piece of code that checks the current .NET installation and installs+reboots if needed.
If possible, downgrade your application's .NET version to 4.5.2 to save the hassle of restarting the node.
We have two Azure cloud service solutions currently using Storage SDK 2.2. We are upgrading to Storage SDK 2.6 but cannot upgrade and support existing version from the same development environment. If the emulator is upgraded the solution with the older SDK binaries fails. Likewise, the newer SDK binaries do not work with the older emulator.
What is suggested for a mixed SDK version scenario like this? Are separate development environment really required?
