I am building a Function App in C# with a compiled library. I deploy the code from the CLI and that's all fine.
Checking the file system with KUDU I can see all the files are updated, the *.dll is updated (the timestamp), but executing the function I get a result from an earlier build.
I execute the function locally from Visual Studio and everything is fine and outputs are as expected.
I can sometimes get the new build used by restarting the site from KUDU, but that's really not desired.
Any idea? I never had these issues when deploying through Github.
Where is your assembly deployed? If deploying the assembly to a folder outside of the actual function folder, please add that to the watchDirectories configuration in your host.json file.
You can find more information about that setting here.

I published my Azure Function, it run as expected. Then I updated the code a bit without changing any configurational value. Now my function.json file is missing in Azure and my function is not running...
I published with new profile. I was expecting to see function.json file.
Glad #FurkanKaracan, that you have resolved the issue by restarting the IDE and redeploying it.
Function.json file missing issue will be caused if the function project is deployed with Runtime Issues.
That file is generated by the Function SDK in .csproj file Microsoft.NET.Sdk.Functions NuGet Package.
Any Changes to this file configuration code bindings are not allowed.
I have checked the following test cases to make the function.json file missing in the Code+Test menu:
Disabled the Function and redeployed from local IDE.
Published Several times by making function code changes through IDEs and CLI Commands.
Checked the Kudu Site of my Function App for every publish/deploy.
That file was visible perfectly how many times I redeploy the project to function app in the Azure Portal.
As per my experience, it might be some deployment issues while publishing.
Refer to this MS Doc for more info on function.json file.
Restarting visual studio and redeploying the app fixed the issue. I really hate microsoft's technologies...
I met an issue when using Azure function.
I create a Azure Functions v1(.Net Framework) Http Trigger template in VS. But when I try to run it directly, exceptions thrown.
I am using latest version of VS(15.6.7) and Azure Functions and Web Job tools(15.0.40502.0).
When I run it first time, no prompt for installation of anything, it runs on 1.0.10 Azure Function CLI. After I restart my VS and try to run it again, VS asks to download 1.0.12.1 Function CLI. The download seems failed as I still see 1.0.10 on the tile of window. The exception remains all the time.
Any idea? It doesn't make sense since I just try to run a template.
The root cause is shown in your screenshot.
Starting Host(...,Version=1.0.11232.0)
It means your function Cli is 1.0.4 other than 1.0.10 actually, here's release note of 1.0.4. After tests, find that old version does cause this exception. This version issue roots in failing to download latest Azure Function Core Tools trough VS.
Update for official solution
Handle downloading problem of Azure Function Core Tools. Try the first option to download using VS again, if it still fails, use the second option, PS scripts.
Below is the original solution, similar to the first and third official option, just ignore it
More Details
Azure Functions and Web Jobs Tools is updated to 15.0.40502.0 recently and mechanism of using local function Cli is also changed. Release Notes.
Tools now consume a feed which keeps templates, build tools, and the runtime up to date whenever there is a change made in the service.
The first time we create an Azure function after this update, we can see the tip on the dialog Making sure all templates are up to date.... It means VS is downloading necessary cli and templates to this folder C:\Users\UserName\AppData\Local\AzureFunctionsTools.
After a while, we can see the tip changes as
If we don't wait the downloading to complete and create project directly, it will prompt that VS is downloading 1.0.12.1 Cli. And everything should work fine after that.
As for your problem, I reproduce it once due to slow network. It fails to download those files and tries to use old version cli downloaded by VS before.
Solution
I recommend you to delete AzureFunctionsTools folder and restart your VS to download it again.
If it still fails to download, you can download it manually.
You can find download link of cli, itemTemplates and projectTemplates in C:\Users\UserName\AppData\Local\AzureFunctionsTools\feed.json.
And the folder structure in C:\Users\UserName\AppData\Local\AzureFunctionsTools\Releases\1.0.12.1 is like this
cli
--func.exe
....
templates
--ItemTemplates.nupkg
--ProjectTemplates.nupkg
manifest.json
Content of manifest.json
{
"ReleaseName": "1.0.12.1",
"CliEntrypointPath":"C:\\Users\\UserName\\AppData\\Local\\AzureFunctionsTools\\Releases\\1.0.12.1\\cli\\func.exe",
"TemplatesDirectory": "C:\\Users\\UserName\\AppData\\Local\\AzureFunctionsTools\\Releases\\1.0.12.1\\templates",
"FunctionsExtensionVersion": "~1",
"SdkPackageVersion": "1.0.13"
}
The project was generated through Ionide and Visual Studio Code. I'm deploying to an Azure WebApp through GitHub.
The GitHub repository is: https://github.com/laygr/suave-dummy
The activity log says:
Command: build.cmd
The system cannot find the path specified.
�
The system cannot find the path specified.
D:\Program Files (x86)\SiteExtensions\Kudu\59.51109.2534\bin\Scripts\starter.cmd build.cmd
It is as simple as a Suave app gets. I hope that this can help others.
Edit
After restarting fresh again (new repo, new web app, new day, new hopes), azure showed a different error which allowed me to figure out the rest. I'll leave the repo so that anyone can see how to deploy the simplest Suave app as an Azure Web App through GitHub
So, after an improvement on the error shown by Azure, I could figure out how to deploy the app.
I had to:
remove .exe from the .gitignore generated by Ionide for Visual Studio Code.
create .deployment
create web.config
modify the build.cmd (I copied it from somewhere else)
modify the build.fsx to perform the correct build
modify the startup file (suave-dummy.fs) to use the correct port
Feel free to check the repo to see what I mean in code. Relevant files:
.gitignore
.deployment
suave-dummy\WebHost\web.config
build.cmd
build.fsx
suave-dummy\suave-dummy.fs
phew!
I am publishing my node js site to azure using this tutorial - http://blogs.technet.com/b/sams_blog/archive/2014/11/14/azure-websites-deploy-node-js-website-using-visual-studio.aspx
I get the following error, as mentioned in one of the comments on the blog, any idea what this error is about and how do I fix this ? I am able to run my app locally no issues with that.
Error: InvalidParameter
Parameter name: index
P.s : the site is like a very basic "Hello world" kind of site, this is the first time I am using and deploying to azure too.
I created a new project as a "Blank Azure Node.js web application", and replaced the resulting package.json and .js files with what I had before, and it publishes fine now
All was working fine for and suddenly got the error! I pretty sure it something in the project as it's now happening on vs2013 and vs2015 on different computers.
Its something to do with Templates after a lot of searching. For me Azure TFS CI got things working again if possible for you?
I had this issue with some projects but not with others, all created in a similar way. So I went thought every change and every setting I could until eventually i worked it out. I didn't want to give up and just remake them.
Basically its file paths, the first thing you notice is that it errors very quickly compared to a usual publish, the first thing that is triggered is a build but unlike heavy framework languages there not really much to actually build.
Like all builds for VS it pops out a bin folder take not of where this appears. This is the key, you want this to appear in the root of your deployment usually at the same level as the publish profile.
Before I moved my projects to VS, TFS and Azure, I used to use git and used the azure push and deployment as part of git, so I instinctively structured my folders in the similar fashion with src folder and all the extra VS baggage in the a directory higher.
This is where I noticed bin folder, so re-structured my solution and made changes to .njsproj (notepad) and moved to be inline with source code and re-added it yo my solution.
Technically speaking this a bug within VS as it allows to create the project and specify different locations which is all fine unless you want to build and publish locally.
Once you get your head around what is going on you should be able to solve this problem easily and not make the same mistake in the future. If anyone is still confused comment and ill grab some screen shots.
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.
