Yes! IronBarcode can be used to read and write QR/barcodes in .NET applications hosted on Azure services. IronBarcode has been thoroughly tested on multiple Azure platforms including MVC websites, Azure Functions, and many more.

Pre-requisites

1. Install IronBarcode to Get Started

First, install the NuGet package on the NuGet website.

Install-Package BarCode

As an alternative, the IronBarcode.dll could also be downloaded and added to your project.

2. Performance and Azure Tiers

We recommend at least using the Azure B1 service plan, as it's suitable for most of our users' use cases. Systems that require higher throughput will need a higher service plan.

3. Framework Choice

.NET Standard, Core, and Framework projects are all compatible with IronBarcode.

4. Docker on Azure

One way to gain the ability to control performance and stability with IronBarcode on Azure is to use Docker. To learn how to use IronBarcode with Azure and Docker, have a look at this tutorial.

5. Official Azure Function Support

IronBarcode currently supports Azure Functions V3 and V4.

Working Azure Function Code Example

Tested on Azure Functions v3.3.1.0+. Here is a code sample:

using System;
using System.Net;
using System.Net.Http;
using IronBarCode;
using Microsoft.AspNetCore.Http;
using Microsoft.Azure.WebJobs;
using Microsoft.Azure.WebJobs.Extensions.Http;
using Microsoft.Extensions.Logging;
using System.Net.Http.Headers;

public static class BarcodeFunction
{
    // Azure Function triggered by HTTP request.
    [FunctionName("barcode")]
    public static HttpResponseMessage Run(
        [HttpTrigger(AuthorizationLevel.Anonymous, "get", "post", Route = null)] HttpRequest req,
        ILogger log)
    {
        log.LogInformation("C# HTTP trigger function processed a request.");

        // Set the license key for IronBarcode if needed.
        IronBarCode.License.LicenseKey = "Key";

        // Create a QR barcode from a string.
        var myBarCode = BarcodeWriter.CreateBarcode("IronBarcode Test", BarcodeEncoding.QRCode);

        // Prepare the HTTP response to return the barcode image.
        var response = new HttpResponseMessage(HttpStatusCode.OK)
        {
            Content = new ByteArrayContent(myBarCode.ToJpegBinaryData())
        };

        // Set content headers for attachment and content type.
        response.Content.Headers.ContentDisposition = new ContentDispositionHeaderValue("attachment")
        { 
            FileName = $"{DateTime.Now:yyyyMMddmm}.jpg" 
        };

        response.Content.Headers.ContentType = new MediaTypeHeaderValue("image/jpeg");

        return response;
    }
}

using System;
using System.Net;
using System.Net.Http;
using IronBarCode;
using Microsoft.AspNetCore.Http;
using Microsoft.Azure.WebJobs;
using Microsoft.Azure.WebJobs.Extensions.Http;
using Microsoft.Extensions.Logging;
using System.Net.Http.Headers;

public static class BarcodeFunction
{
    // Azure Function triggered by HTTP request.
    [FunctionName("barcode")]
    public static HttpResponseMessage Run(
        [HttpTrigger(AuthorizationLevel.Anonymous, "get", "post", Route = null)] HttpRequest req,
        ILogger log)
    {
        log.LogInformation("C# HTTP trigger function processed a request.");

        // Set the license key for IronBarcode if needed.
        IronBarCode.License.LicenseKey = "Key";

        // Create a QR barcode from a string.
        var myBarCode = BarcodeWriter.CreateBarcode("IronBarcode Test", BarcodeEncoding.QRCode);

        // Prepare the HTTP response to return the barcode image.
        var response = new HttpResponseMessage(HttpStatusCode.OK)
        {
            Content = new ByteArrayContent(myBarCode.ToJpegBinaryData())
        };

        // Set content headers for attachment and content type.
        response.Content.Headers.ContentDisposition = new ContentDispositionHeaderValue("attachment")
        { 
            FileName = $"{DateTime.Now:yyyyMMddmm}.jpg" 
        };

        response.Content.Headers.ContentType = new MediaTypeHeaderValue("image/jpeg");

        return response;
    }
}

Imports System
Imports System.Net
Imports System.Net.Http
Imports IronBarCode
Imports Microsoft.AspNetCore.Http
Imports Microsoft.Azure.WebJobs
Imports Microsoft.Azure.WebJobs.Extensions.Http
Imports Microsoft.Extensions.Logging
Imports System.Net.Http.Headers

Public Module BarcodeFunction
	' Azure Function triggered by HTTP request.
	<FunctionName("barcode")>
	Public Function Run(<HttpTrigger(AuthorizationLevel.Anonymous, "get", "post", Route := Nothing)> ByVal req As HttpRequest, ByVal log As ILogger) As HttpResponseMessage
		log.LogInformation("C# HTTP trigger function processed a request.")

		' Set the license key for IronBarcode if needed.
		IronBarCode.License.LicenseKey = "Key"

		' Create a QR barcode from a string.
		Dim myBarCode = BarcodeWriter.CreateBarcode("IronBarcode Test", BarcodeEncoding.QRCode)

		' Prepare the HTTP response to return the barcode image.
		Dim response = New HttpResponseMessage(HttpStatusCode.OK) With {.Content = New ByteArrayContent(myBarCode.ToJpegBinaryData())}

		' Set content headers for attachment and content type.
		response.Content.Headers.ContentDisposition = New ContentDispositionHeaderValue("attachment") With {.FileName = $"{DateTime.Now:yyyyMMddmm}.jpg"}

		response.Content.Headers.ContentType = New MediaTypeHeaderValue("image/jpeg")

		Return response
	End Function
End Module

In this code:

• We define an Azure Function with the name "barcode."
• The function is triggered by an HTTP request and logs a message when processed.
• We specify the license key for IronBarcode (replace "Key" with your actual license key).
• A QR code barcode is generated using BarcodeWriter.CreateBarcode.
• The barcode image is converted to JPEG format and included in the HTTP response.
• The response content is set as a downloadable attachment with the current date and time as the file name.
• The response content type is set to "image/jpeg" to indicate the image format.
