Visual Studio Code – Starting Azurite when debugging (F5) Azure Functions with VS Code

Does anyone know if there’s a simple, recommended way to always background start/stop Azurite using a temp directory when F5 debugging in VS Code, like Visual Studio proper does, maybe through the launch.json? I have the Azurite installed, so I can manually start the service and it works, but I find all of the __*__ files in my project directory to be really annoying. Not to mention the Azurite: Clean command never cleans everything due to file-level locks. My environment is up to date and currently as follows:

  • OS: Windows 11 23H2 (OS Build 22631.3527)
  • VS Code: 1.89.1 (w/ Azure, Azure Functions and Azurite extensions)
  • Azure Function Core Tools: 4.0.5700
  • Model: dotnet-isolated
  • Language: C#
  • local.settings.json contains "AzureWebJobsStorage": "UseDevelopmentStorage=true"

    This has been annoying me for years and I finally found an answer after digging into the Azure Functions issue log and finding Issue 3876. Until something is done to resolve this, the simple fix is to replace

    {
  //...
  "Values": {
    "AzureWebJobsStorage": "UseDevelopmentStorage=True"
    // ...    
  }
}

    with this

    {
  //...
  "Values": {
    "AzureWebJobsStorage": "DefaultEndpointsProtocol=http;AccountName=devstoreaccount1;AccountKey=Eby8vdM02xNOcqFlqUwJPLlmEtlCDXJ1OUzFT50uSRZ6IFsuFq2UVErCz4I6tq/K1SZFPTOtr/KBHBeksoGMGw==;BlobEndpoint=http://127.0.0.1:10010/devstoreaccount1;QueueEndpoint=http://127.0.0.1:10011/devstoreaccount1;TableEndpoint=http://127.0.0.1:10012/devstoreaccount1;"
    // ...    
  }
}

    I have followed below steps to create a .NET8 Isolated Blob Trigger Azure function and able to run the function without running the Azurite manually, also could avoid creating extra(__*__) files.

    • Open Command Palette in Visual Studio Code(Ctrl+shift+p), select Azure Functions: Create Function.

    enter image description here

    • Select the Project folder, runtime and the function trigger.

    enter image description here

    • Select Use Azurite Emulator for local storage.

    enter image description here

    The function gets created successfully.

    local.settings.json:

    {
  "IsEncrypted": false,
  "Values": {
    "AzureWebJobsStorage": "UseDevelopmentStorage=true",
    "FUNCTIONS_WORKER_RUNTIME": "dotnet-isolated"
  }
}
    • Start debugging the function, this will run successfully without creating any extra files in the project folder.

    Output:
