            Why is an Azure Function on .NET 6 looking for System.ComponentModel Version 6.0.0.0?
            Asked 2022-Mar-30 at 09:48

            I am deploying an Azure Function called "Bridge" to Azure, targeting .NET 6. The project is referencing a class library called "DBLibrary" that I wrote, and that library is targeting .NET Standard 2.1. The Azure Function can be run locally on my PC without runtime errors.

            When I publish the Azure Function to Azure, I see in Azure Portal a "Functions runtime error" which says:

            Could not load file or assembly 'System.ComponentModel, Version=6.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'. The system cannot find the file specified.

            I do not target System.ComponentModel directly, and I don't see a nuget package version 6.0.0 for "System.ComponentModel" available from any nuget feed. Why is the Azure function looking for this version 6.0.0 of System.ComponentModel? If that version does exist, why can't the Azure Function find it?

            Here are the relevant parts of the csproj for the "Bridge" Azure Function:

            The .net standard you are using 2.1 but ,Microsoft.Azure.Functions.Extensions can be support upto .NET Standard 2.0

            You should add the below package to your function app and deploy to Azure again.

            I'm new here, sorry if the post is incomplete.

            I'm trying to deploy a python script on azure that interacts with blobs. The script works fine in local : i can interact with my storage account, upload & download blobs... But when I deploy my function on azure, it won't run. The logs says no module named azure.storage exists.

            Thing is, on my computer i had to pip install this module.

            Should i add this module on azure web ? How am I supposed to do such a thing ?

            Simply going through microsoft source code of Microsoft.Azure.WebJobs.Script.WebHost.DefaultSecretManagerProvider we can find it's creating a new instance of KeyVaultSecretsRepository and pass to it the valtUri under the environment name public const string AzureWebJobsSecretStorageKeyVaultUri = "AzureWebJobsSecretStorageKeyVaultUri";

            you can add the 'AzureWebJobsSecretStorageKeyVaultUri' configuration key with your Vault URI to your app configuration and that will make it work.

            ANSWER

            Answered 2021-Dec-03 at 08:44

            As said by @bmcfee here :

            This is not a librosa problem -- if the file won't load, it's because audioread is unable to decode it. It appears to be using the ffmpeg backend, which means (probably) that ffmpeg can't decode it either. That the file itself is corrupt. I suggest putting some debug prints in to track down exactly which file is causing problems.

            So, this is an dependency bug.

            I was just trying to use SubscriptionClient for the first time and was running into this same issue, so I'm glad it wasn't just me.

            I did find that they release a new version of the module on 2021-11-25, (see the release notes here: https://github.com/Azure/azure-sdk-for-python/releases/tag/azure-mgmt-subscription_2.0.0) and it lists a breaking change of "Removed operation group SubscriptionsOperations". The documentation doesn't seem to reflect this, and it's not clear what you're supposed to do instead to list all subscriptions.

            I got it working by pinning azure-mgmt-subscription to 1.0.0.

            I have to agree that the documentation is contradictory.

            So, let's ignore the docs 😅 and go straight to the source: https://github.com/Azure/azure-sdk-for-python/blob/main/sdk/servicebus/azure-servicebus/azure/servicebus/_common/message.py#L63

            This tells us that the correct keyword argument is application_properties.

            Reminder: this answer is pointing out the current (at the time of writing) code in the main branch. This appears to be for version 7+ of the azure-servicebus package.

            This is because you only have read permission in your SAS token (sp=r). In order to update the blob, you will also need write permission in your token.

            Please create a SAS token with both read and write permission and you should be able to update the blob. Your SAS URL should look something like:

            Support

            While many languages are supported, their level of support differs in important ways, making some languages more suitable than others for certain workloads. These differences are explained according to host version:. In V1, the first class languages are C#, F#, and Javascript/Node.js. Functions written in these languages are run in process and are suitable for any workload. The remaining languages are considered experimental. Functions written in these languages are scripts that are run out of process. While there are many scenarios where this is acceptable, it won’t be acceptable for high load scenarios where the overhead of a new process for each invocation won’t scale. In V2, running a language out of process is no longer considered experimental. Out of process languages include JavaScript/Node.js (GA), Java (GA), Python (GA), and PowerShell (GA). C# and F# are still run in process. For more information about Supported Languages, see [this Microsoft Docs page](https://docs.microsoft.com/azure/azure-functions/supported-languages).
