As per our discussion, we should ensure that customers are aware that Microservices can be built on Azure Functions.

Hi,

I have a .dll I'm working on and using on the Azure Functions. The methods from .dll worker fine untill I added some new methods to it.
When I upload the new .dll to the bin folder I created on the Azure functions and try to use the new methods I added I get

2016-10-12T15:25:02.920 Function started (Id=xxxxxxxxxxx)
2016-10-12T15:25:03.045 Function completed (Failure, Id=xxxxxxxxxxxx)
2016-10-12T15:25:03.060 Exception while executing function: Functions.Report. mscorlib: Exception has been thrown by the target of an invocation. Report: Method not found: 'Void Company.Product.Compat.Report.SomeEngine.TestMethod()'.

It says that my TestMethod(); is missing. I am sure I uploaded the correct .dll versions as I tried creating a new seperate project, included that .dll's and tried to invoke the new methods I added and it worked, so they are there.

Compilation is successful when I add the .dll;s to Azure Functions, it's just that they are missing in runtime.

Could it be that Azure Functions compiler cached the dll's that I had before and is now trying to use them every time? That's the only think I can think of.

I tried deleting the Azure Function and creating a new one but the problem persisted.

EDIT: I tried to up the version of my .dll and it worked the first time I tried it. Now my TestMethod() runs normally, however when I added TestMethod2(), upped the .dll version again and rebuilded it, put it on Azure Functions the problem is the same. now TestMethod2() is not found. Maybe I just hit the time frame that Azure cleared it's cache and cached the .dll with only TestMethod() version on it.

This is a problem since I have to change the .dll frequently to test something out.

Thanks

From Mathew Charles:
I’m answering questions often (like this one this morning http://stackoverflow.com/questions/38006649/configuring-notification-tag-for-azure-function) on parameter binding. I’m wondering if we have overview doc anywhere on how binding works in general. Another possibility would be for us to indicate in the templates/bindings somehow that binding parameters are supported for various properties, but I don’t want a bunch of duplication.

I expected to see a little overview section in https://azure.microsoft.com/en-us/documentation/articles/functions-triggers-bindings/. I think it would make sense to have something on that page that gives an overview of %% and {} binding functionality that applies to all the various bindings.

This is making a "transcript" of the video version

We should ensure that we have an example which covers the CloudQueueMessage implementation as well, or at least provide a link to some relevant content.

https://azure.microsoft.com/en-us/documentation/articles/functions-bindings-storage-queue/

There are two sections which aren't rendering properly:

• Trigger sample in Node.js
• Output sample in C#

Article explaining how to use it with Azure Functions

There are various App Service features that work similarly in Azure Functions, should make a resources page and link out to them.

We had other writers in Erik's org read and provide some useful feedback on the Runtime Concepts topic, which was the beginning of the dev reference.

• SendGrid
• Twilio

Greetings,

are there any plans to support .NET Core in addition to .NET 4.6 in the future?

Thanks and best regards

Examples of content to include:

• Functions should be stateless
• Use queues between functions
• Functions within an app share resources. If you're using something a Function App in production, don't add test functions to it.

Adding code samples for F# to existing documentation.

I noticed my bill was about $20 fatter last month... upon investigation, it was from a storage account tied to a dynamic plan Function app. This app is not used in prod. However, it had a timed function that ran every five minutes or so as an experiment to help Azure resolve another issue. Azure/azure-functions-host#298 (comment)

I'm wondering if there is a bug in the Function App container, if it's writing 60k log entries every time there's a cold start, or if it's just doing that for no reason...

Anyway, it's writing about 60k files per minute. I terminated the app container.

We need to document in the Storage Account bindings section that we don't support Blob Only Storage Accounts.

As the title says, Dynamic plan Function Apps can't change their Dynamic Plans. We should document this.

Add doc support for SendGrid bindings

Replace the existing article: https://azure.microsoft.com/en-us/documentation/articles/functions-run-local

See CLI readme here: https://github.com/Azure/azure-functions-cli/blob/master/README.md

Update: https://docs.microsoft.com/en-us/azure/azure-functions/functions-reference-node#node-version--package-management

First, apologies if this doesn't belong here. It is regarding the tooling here:
https://www.npmjs.com/package/azure-functions-cli

If there is a space in your path, then you cannot run the function. ("func run MyAzureFunction") For example if your local user account has a space in it, or the project you are working on itself. I couldn't find a workaround apart from creating a new local account without a space and removing the space from the project.

Thanks,
Adrian

There is an email thread that just started on this... I will update this thread with that conversation

I have a sample of this here: https://github.com/SyntaxC4-MSFT/CoderCards

I was building a C# web hook that sends a notification out. The doc (https://azure.microsoft.com/en-us/documentation/articles/functions-triggers-bindings/#azure-notification-hub-output-binding) sample in C# uses an out parameter, however, when creating a web hook template we use async methods (which are the recommended way we want folks to write functions in C#) so the sample doesn’t compile. I suggest we refresh the doc sample to be consistent with our templates. In my case I wanted to output to other bindings so I couldn’t just copy and paste the whole sample.

It's possible to have static classes in a shared assembly, where multiple function invocations share this same loaded class.

@fabiocav Can you confirm the behavior that should be documented?

Customers may be confused when they delete a function app but keep the storage account, and their files are still there. Similarly, if they delete their storage account, they will delete all of their code. This should go in the Dynamic Compute article (https://docs.microsoft.com/en-us/azure/azure-functions/functions-scale).

Use the text from this issue: #173

We should make sure that we document what locales are available for the Azure Functions Portal if they differ from the standard Azure Portal listing of available locales

Hello!

I'm fairly new to azure functions but as far as I understand it's not possible to upload a exe file and run that as a function, is that something that is planned? I really do prefer not to publish plain source code and would prefer to have deployment go though a more traditional build > package > test > deploy cycle.

I've previously used webjobs for this however they don't really feel like first class citizens in azure and have a few other issues such as possibility to be deleted by accident by a web deploy to the same site, no restart functionality, some times shutting down and so on. it feel like azure functions would be able to fill this gap, if only you could use it with precompiled code.

Is this something you have any plans for?

This is published here...

https://azure.microsoft.com/en-us/documentation/articles/functions-bindings-event-hubs/

However, I need to add a couple more code examples to the reference. Should have that completed before the end of the week.

We've noticed that there is some confusion on the different Plan models:

Hopefully this can be clarified by Calvin or @dariagrigoriu

Original issue created by @SeanFeldman here: Azure/azure-functions-host#739

See http://stackoverflow.com/questions/39855409/how-do-i-use-binder-to-perform-dynamic-bindings-in-my-c-sharp-function for details, including the blob post Sean wrote :)

And with monitoring I mean support for the Event Hub compatible name/enpoint (as described in https://azure.microsoft.com/nl-nl/documentation/articles/iot-hub-operations-monitoring/)

This takes away the effort of putting StreamAnalytics/Eventhub between IoTHub and Azure Functions.

(note: This is not the same as issue: #31)

New Photos of recent Portal updates

In the Functions runtime, NuGet restore works by comparing project.json and project.lock.json. If they match, NuGet restore is NOT performed, and the packages won't exist. So, project.lock.json should never be deployed and should be in .gitignore.
