Azure Functions
Azure Functions is an event driven, compute-on-demand experience that extends the existing Azure application platform with capabilities to implement code triggered by events occurring in other Azure services, SaaS products, and on-premises systems. With Azure Functions, your applications scale based on demand and you pay only for the resources you consume. Azure Functions provides an intuitive, browser-based user interface allowing you to create scheduled or triggered pieces of code implemented in a variety of programming languages.

Add binding to Key Vault
Functions often need password, API keys, and connection strings to connect to other services and retrieve data. It would be great if those secrets could easily be obtained from Key Vault.
264 votesThis is a good idea. We’ll look at this later when we’re ready to start adding more bindings (likely after we GA).

Enable dependency injection in C# Functions
It would be useful to have a form of DI in our C# Functions, so we can consistently inject things like our logger class, or other Autofac DI services, into every C# Function we create.
I'd like to create a SDK package which developers can import into their Function and get access to some common functionality via DI, to remove boilerplate redundancy.
Any solution for this kind of thing?
181 votesthanks for the continued support!
We’re still planning to add this, and will provide more granular updates to the github issue: https://github.com/Azure/Azure-Functions/issues/299
Thanks!

Golang support for Azure Functions
C# and other environments are already supported; it would be nice if Go / Golang was one of them. I'd love to handle web requests using Golang + Azure Functions.
It could provide the "HTTP Requests" via the stdin, while the "HTTP Response" can be given via the stdout. (or whatever those two are called on Windows ;-) )
133 votesWe’re now investigating plans to support Go in Functions. Still in the early planning stages but we’d love to hear about your scenario and expectations from Go in Functions. Please let us know if you’d be willing to participate in a 30 minute call to engage further!
Thanks,

Enable custom 3rd party authentication providers
Outside of out of the box providers like facebook and google, provide samples and guidance on how to authenticate with others like LinkedIn.
102 votesWe’re moving this back to the unplanned status, as the started work was not completed, and we don’t have a current ETA.
We’ll update the status again once we have more information. This is still an item we’d like to do at some point.

Support for session-enabled Azure Service Bus queues/subscriptions
Currently the queue/subscription trigger only works with queues and subscriptions that does not use sessions (RequiresSession = false). It would be very useful if the runtime would detect that sessions are enabled and adapt accordingly. As far as I can see, the actual function code would not even have to be aware.
73 votesThis is a good idea and something we want to support but still need to do more investigation on our part. In the meantime as a mitigation the Azure Logic Apps service bus trigger does now support sessions and session-enabled queues/topics.

Add TypeScript support to Azure Functions
Please support writing TypeScript in Azure Functions when you're creating Node functions
66 votesSupport for TypeScript is on our backlog. Unfortunately, there’s isn’t an ETA to share at this time but we’ll keep this thread updated with the latest. Thanks for your patience!

Add max calls/per day|hour|minute configuration for throttling
Now- any light ddos attack that Azure will not recognize- will affect me and my account. If I know that my service shouldn't receive more than 10000 calls per day, but I can't setup limits on incoming requests.
"Daily Usage Quota (GB-Sec)"- not bad idea, but it's something internal and synthetic for me. Call/per day- is much more native metrics for users.
49 votesKeep the votes/comments coming – still have this under review.

SQL Azure trigger support
Azure functions are great, but a lot of application logic is driven by data in SQL Azure DBs. It would be great to have a trigger based on a SQL Azure row data.
41 votesThe path forward with this will be our event grid integration. Event Grid currently doesn’t support SQL events, but there’s work on the backlog to enable this.

Trigger Azure Function From Table Storage
Allow create, update and delete on a table storage row to trigger an Azure Function.

Allow websockets ( SignalR ) feature in azure serverless using Functions
Currently Websockets ( SignalR ) like continuous stream feature is not possible with Azure server less, please add this feature so we can make more use of azure functions.
28 votesThis is tricky because it requires a persisted stateful connection, which doesn’t align well with the “scale down to zero” approach that Functions takes. We’ll still be looking into it, though.

Handle Storage Queue/Service Bus messages in batches
I want to be able to handle multiple messages per function call - we are using a third-party web service which works much more efficiently if the messages are passed to it in batches. I know we could use a timer to trigger the function and grab messages from the queue ourselves but if we do that the function won't scale out automatically.
26 votesThe under review status update is still valid, just posting again since its been a year.

Allow setting maxConcurrrentCalls per Function
I want to make sure that Queue triggers process in order (i.e. I want to save data from message 1 before message 2 tries to save), but according to the docs it looks like multiple queue messages can be processed concurrently. The setting for that can be changed through the host.json file's "serviceBus.maxConcurrrentCalls". For topics, though, I don't care about running in sequence, so concurrent executions are fine. I want to have queues trigger with maxConcurrrentCalls = 1 and topics set to something higher. Therefore, it would be great to define that at a function level. If my understanding of…
22 votesWe have a number of things floating around to improve this experience, including allowing concurrency to be modified. We’ll be working on exposing these over the next few months. Will update this when there is news.

Need to allow GDI+ access for running ReportViewer inside of Consumption plan in Azure Functions
Need to allow azure functions running in consumption plan (with easy scaling) to be able to use ReportViewer to generate PDF, Excel and Word exports. Only appears to be possibly available to be used with Azure Functions in App Service plan https://azure.microsoft.com/en-us/blog/pdf-generation-and-loading-file-based-certificates-in-azure-websites/

Function App Service support for Azure B2C
If I build a web app using Azure B2C for authentication, I'd like to use it as the authentication provider for Azure Functions too. Although I can set up the same providers, using B2C would be cleaner and enable me to support users with local logins (traditional username and password) too.
18 votesWe do have preliminary support for B2C. Please see the following blog post for an overview:
https://cgillum.tech/2016/05/27/app-service-auth-and-azure-ad-b2c/There are some known issues, such as working with password reset policies. We will continue to work on this.

Add support for Kafka Streams from HD Insight
Azure Functions should be able to be triggered from Apache Kafka. The triggered function should be able to be configured for a specific consumer group, with options to explicitly commit the consumer's offset.
Ideally Kafka Streams could be supported, with special support for local storage of KTables.
18 votesGood suggestion. We’ll review this with the HD Insight Kafka team.

Nuget support in a modern way
Hi, it's great that we can upload some binaries and than referencing to dlls directly, also- we can reference to nuget in project.json https://docs.microsoft.com/en-us/azure/azure-functions/functions-reference-csharp#package-management
But project.json was announced as a legacy thing even for asp.net core. in RC1 for VS2017- you will see that even in asp.net core we are not using project.json anymore.
We need some consistent/up-to-date experience with other product.
16 votesWe are planning on moving to the new project format which has just been released for .NET core projects.

Provide high-level monitoring experience (similar to Data Factory)
It would be great to have high-level monitoring available that visualizes all the functions in an instance, similar to how Azure Data Factory does it in the Monitor-feature.
Following information would be interesting:
- Failure rate per function
- Dependency metrics per binding, per function _(similar to AI Dependency)_
- Function state _(enabled/disabled)_
- ...16 votesUpdate 2/5/18: We’re still actively working on improving this experience.
We’re working on providing this in a couple of ways:1. Application Insights for deep insights into how your Functions are running
2. Azure Monitoring integration for simple insights (aggregated failure/success rate/latency/etc.)is already partially there. #1 will be around soon.

The dynamic tier should never run out of sockets
If you have too many connections, you can get SocketExceptions. The dynamic tier was meant to stop us from having to think about server instances, but with a connection limit, the dynamic tier is useless and we are back to the standard service plans.
15 votesWe have no active plans to update the socket connection limits per Function execution since it is a finite resource, like CPU/Memory, but we are planning on improving the experience to prevent socket exhaustion issues from competing Function executions.
To clarify, Standard plans are not “unlimited”, but rather are limited at the VM level, rather than the Sandbox level like Consumption is.
If there is a desire to raise the limit to some slightly higher number, we’d be open to a specific number and investigating if it fits into our resource model.

Support Service Bus trigger with use of SAS token
In our company we are using Service Bus with a framework that deals out the SAS tokens to queues. These tokens are living for few days only and concern hierarchical queues (eg. queue name could be productA/event-type-B/subtypeC) and only Listen policy.
This would mean that listening on a different level then root level of namespace would be needed.
Best if also the whole connection to SB described by this token would be separate object from the Function, so we could modify it (by altering with new SAS token/whole connection string) without modifying the Function code (as API Connections in Logic…14 votesNice idea – keep the votes coming.
