C# 8.0 C#

This post is about the new C# 8.0 feature Default implementations in interfaces. This feature helps you to provide an implementation for your new method in an interface. So you won’t break existing implementation by adding a new method. From the documentation - An interface member can now be specified with a code body, and if an implementing class or struct does not provide an implementation of that member, no error occurs. Instead, the default implementation is used.

Azure AzureBlob

This post is about getting all the blobs in a container and change the content type. This tip or snippet is quite useful in scenarios where you want to change content type of big number of blobs. This is a tip or snippet more than a blog post. I faced this issue in my current project, where our application used to push images to Azure Blob, but we were not setting the content type, and by default the content type is application/octet-stream. Because of this, when we used to browse the URL, instead of displaying it in the browser, browser used to show a download prompt. In this I am using a dotnet core console app, which will get all the blobs and if the extension of the file is jpg, setting the content type to image/jpg.

Resizing Images using Azure Functions

ASP.NET Core Azure Serverless

This post is about how to resize images uploaded to a blob storage using Azure functions. In my current project, system used to resize the image while uploading the image to blob storage. This approach got two major drawbacks - the process will take some time and the resize is implemented using System.Drawing - which is not recommended to use in Server side applications. By implementing a function - which triggers while someone uploads a photo to blob storage - using ImageSharp - resize the image. Since the code is very minimal I am using the Azure portal to build the Azure Function. In the portal, click New and Search for Functions, select Function App. And you need to provide a name, resource group and storage.
