I have written an Azure Function App by using the User Interface of Azure Portal. The code is written in C#.
Now, I want to:
download all of the relevant code and configuration files of this
function app
Create an IDE project (e.g. IntelliJ, Visual Studio Code, ...)
store it in a git repository
Deploy the code from IDE or command line to Azure and thereby replacing the previously written Azure function.
So far, I have found only documentation on how to initiate Azure function projects with no previous code. Does somebody know how to do above?
Yes, you could go to your function Overview page, click on Download app content as shown below.
And in your situation, you want configuration files, so select the Content and Visual Studio Project and Include app settings in the download. What is app settings? This will include a local.settings.json file which contains your application settings.
Also the third party .dlls are included.
In the VS, select the folder and it will be working.
Update:
Open the function with vs, then just right click the function and choose Publish, it will show you the publish page. Click start, then you will be able to publish it to a existing Function.
Follow this Setting up a CI/CD pipeline for Azure Functions doc which explain each step in detail.

I had developed azure function solution in Visual Studio 2019 and deployed to azure function by downloading publisher .
But accidently I had deleted entire source code in local machine where I could not get even from "recovery software tools" also.
is there any way can I get source code files from azure function development tools in azure portal? or local machine C drive?
If you open up the Azure Function App Service and navigate to the "Functions" section you will be able to open your individual functions and then select the "Code + Test" section and be able to see your function
I don't know if the type of Function you developed impacts your ability to see this source code or not.
When you deployed through Visual Studio, the source was compiled locally and only the DLLs were uploaded. Thus, you cannot directly see your code. However, you can get to your DLLs and download those. Then you should be able to use any decompiler to see your source code again (maybe not as pretty as originally...).
Go to the SCM console to see and download all files: https://{YOURFUNCTIONNAME}.scm.azurewebsites.net/dev/wwwroot/
I have an existing set of functions in an Azure Functions App written in C# Script. I've downloaded the zip file from the Azure portal and opened the directory in Visual Code. I can also log on to the Azure account from Visual Code and can see the functions. If I right-click, I get options to start and stop streaming logs
However, I don't know how to configure my environment so that I can edit and debug these functions locally. I've found instructions for creating a new Function App, but haven't found ones that describe how to work with an existing app.
As mentioned in this post, for now we can't debug(add break points to) C# script(.csx) functions in VS Code.
We can only run csx function both on Azure and locally. Open the function app folder in VS code, follow steps below.
Check function runtime version(~1 or ~2) and follow tutorial to install Azure Function core tools.
If we use ~2 runtime, you need to register binding extensions for all triggers/in/output except Http and Timer triggers.
If we want to use settings(like AzureWebJobsStorage) in Application settings, copy them into local.settings.json. Or we can right click on Application settings of the Function app in VS Code, click Download Remote Settings(In this way, some invalid settings for local env are downloaded as well).
Input Ctrl+` to open terminal and input func host start in terminal to run functions.
For local dev, I do recommend you to use C# pre-compiled code instead of C# script, which is much easier to work with. To do this transformation, follow this tutorial, new a c# function app locally, copy your code in .cs files. We basically don't need to modify the logic code except adding some package and namespace references.
I'm new to Azure Functions and been thrown into a project without a proper introduction and anybody I could ask is out of office. My simple most likely stupid question is; where can I find the actual code?
In the azure portal, the functions are listed as "read-only" and only contains a function.json. The resource is an App Service and it has a couple of functions. There is no link to any git repository in properties.
Read-only Functions would be compiled and published (e.g. through Visual Studio or a CI/CD pipeline.) The Azure Functions Portal engineers are working on a new, improved experience for this but for now, if your Function app has a deployment source configured, you can view it from the Portal in two ways from your Function app:
Platform Features > Deployment Options.
Platform Features > Resource Explorer. In the file tree on the lefthand side, find your Function app's name, and under that, sourcecontrols. Click to expand in the righthand window.
If your Function app doesn't have a deployment source configured (e.g. your team has been publishing code manually) then things get harder. Depending on how your company has set up their source control and what you already have access to, the function.json you see might help: the entryPoint property in a build-generated function.json will give you the full assembly name of that function (e.g. VSSample.HelloSequence.Run). That or the assembly name of the uploaded DLL in the scriptfile property might help you locate the project.
Good luck! Keep posting if you have further questions; we're here to help.
AFAIK, if we create the azure function in the Visual Studio and publish it to Azure(there may be other ways), it will appear in the situation you described like the screenshot.
Actually, the code is existing in the portal, but the code has been compiled, you could access it in the Platform features -> Advanced tools (Kudu) -> Debug console.
If you want to get the .cs file, I think you should ask it for your coworkers, there will not be in azure.
You said that the Azure function is listed as "read-only". Did you check from the Application Settings menu if you can change the Azure function app edit mode to Read/Write?
I have Created a cluster in Azure http://******.######.cloudapp.azure.com:19080
but don't know how to deploy my service fabric project on to it.
Link to application manifest
ApplicationManifest.xml
It's pretty well documented, unless you are getting specific errors, which you then will need to reference to get some worthwhile help
https://learn.microsoft.com/en-us/azure/service-fabric/service-fabric-publish-app-remote-cluster
Your first option is to use the powershell commands. You can also right-click your application in visual studio and select "Publish". Make sure you are using the correct publish profile.
Within Visual Studio, navigate to your Publish Profiles folder under the application and copy/paste the existing cloud.xml file and then rename appropriately. Ensure that you use the correct public facing I.P for your cluster, which will most likely be the load balancer.
The line should look like the following.
<ClusterConnectionParameters ConnectionEndpoint="<YOUR IP>:19000" />
Example:
<ClusterConnectionParameters ConnectionEndpoint="151.41.35.35:19000" />
However, if the cluster is secured you may need additional information. These options are shown within the commented Cluster Connection Parameters of the cloud.xml file.
Right click on the application, select publish and ensure the new publish profile is selected. Visual studio will attempt to validate the connection. Try to publish and keep an eye on the output window for insight in to the process.
A website with webjob not deploying to Azure.
I am having an issue getting a website with an associated webjob console application to deploy using continuous deployment via Visual Studio Online. I am using VS2013 with update 4 and latest Azure SDK.
The website, and the associated webjob, will publish to Azure using direct publish for Visual Studio and works perfectly, so I am confident the publish settings are fine.
The solution will build and work locally fine.
The solution, once checked in, will build and (seemingly) deploy fine in VSO (using CI) and Azure notes the build was successful and shows it as 'Active deployment'.
However, the website and associated webjob will not be updated.
When I have browsed the deployed files after the VSO build and deploy on Azure, all that is happening, is the binaries of the console app are being copied into the bin/ folder of the website.
None of the website files are being updated. It is almost as if it is deploying the wrong project!
If I remove the Webjob and just deploy the website, it will build and deploy fine through VSO - the website will update.
It is adding the webjob that causes some issue with the deployment via VSO.
I am confident all steps are correct to add the webjob to the WebApp, with the correct webjobs-list.json being added to the webapp and webjob-publish-settings.json to the Console app - as I said, publishing the website (with the webjob) direct to Azure works perfectly, and both the site and webjob get updated.
I have searched post after post and tried all manner of things, but none have worked.
Given the fact this published fine direct from VS, and also that the build is completing, it would suggest that something is wrong with the VSO Build Defintion.
My first guess would be to change it from building the solution to instead building the web project only, but this does not seem to work.
I have also tried every Output location setting (both for the solution build and the web project build) - the only one that works and the build completes is the solution (.sln) build with 'SingleFolder' set.
I have been battling this for a couple of days now an I'm a bit stumped!
This also happens if you have a static website being deployed using a Visual Studio solution via VSO with an automated build - unless the Visual Studio project / solution containing the website is changed then the actual site contents will not be redeployed.
I think your hunch that it's deploying the wrong project is correct. If you have multiple "deployable" projects in your solution (and the console app is considered deployable, as this is one way you can host/deploy a webjob), you need to tell Kudu which one to deploy.
You can control it adding a new setting under "app settings" on the "configure" tab for the webapp.
The setting you want is Project and it's a relative path from the solution root to the .csproj file of your web project.
Alternatively, you can specify the setting in a custom .deployment file.
Relevant Kudu documentation here
From the documentation:
You can specify the full path to the project file. Note that this is not a path to the solution file (.sln), but to the project file (.csproj/.vbproj). The reason for this is that Kudu only builds the minimal dependency tree for this project, and avoids building unrelated projects in the solution that are not needed by the web project.
Here is an example:
[config]
project = WebProject/WebProject.csproj
I have also tried every Output location setting (both for the solution build and the web project build) - the only one that works and the build completes is the solution (.sln) build with 'SingleFolder' set
That's the root case of problem.
You can't have SingleFolder as it sets the OutDir which mess up with web job packaging.
I had to introduce a wpp.targets files in each of my web app project to create the publish package to a particular path (using PackageLocation)
So, let each project have that and set the setting to AsConfigured (or Per Project) instead of SingleFolder.
