Azure Storage for Serverless .NET Apps in Minutes
Azure Storage is a quick and effortless way to store data for applications that has high availability, is secure, scales and is redundant. This blog post walks through a simple application that creates a short code for a long URL to easily reference it. It uses Table Storage to map codes to URLs and a Queue to process redirect counts. Everything is handled by serverless Azure Functions. The only prerequisite to build and run locally is Visual Studio 2017 15.5 or later, including the Azure Developer workload. That will automatically install the Azure Storage Emulator you can use to program against tables, queues, ...

.NET for UWP January 2018 Update
Today, we are releasing the .NET for UWP January 2018 Update. This post includes the fix included and instructions on how to update your applications. Security CVE-2018-0786 – Security Feature Bypass in X509 Certificate Validation Microsoft is aware of a security vulnerability in the public versions of .NET Core where an attacker could present a certificate that is marked invalid for a specific use, but a component uses it for that purpose. This action disregards the Enhanced Key Usage tagging. The security update addresses the vulnerability by ensuring that .NET Core components completely validate certificates...
64 bit ASP.NET Core on Azure App Service
![Glenn Condron [MSFT]](https://devblogs.microsoft.com/dotnet/wp-content/uploads/sites/10/letter-avatar/4011b79e8ebc59a586a47a3a8562574d.svg){kind=avatar}
When creating an Azure App Service .NET Core is already pre-installed. However, only the 32 bit .NET runtime is installed. In this post we will look at a few ways that you can get a 64 bit runtime on Azure App Service During the 2.1 timeframe we are hoping to have both 32 and 64 bit runtimes installed as well as enabling the portal experience to switch between the two. 1. Deploy a self-contained application Self-contained deployments don't require .NET Core to be installed on a machine, because they carry the runtime they need with them. Because of this you can deploy a 64bit self-contained deployment to...

Take a Break with Azure Functions
So, it's the Holidays. The office is empty, the boss is away, and you've got a bit of free time on your hands. How about learning a new skill and having some fun? Azure Functions are a serverless technology that executes code based on various triggers (i.e. a URL is called, an item is placed on a queue, a file is added to blob storage, a timer goes off.) There's all sorts of things you can do with Azure Functions, like running high CPU-bound calculations, calling various web services and reporting results, sending messages to groups - and nearly anything you can imagine. But unlike traditional applications and s...
Testing ASP.NET Core MVC web apps in-memory
This post was written and submitted by Javier Calvarro Nelson, a developer on the ASP.NET Core MVC team Testing is an important part of the development process of any application. In this blog post we are going to explore how we can test ASP.NET Core MVC applications using an in-memory server. This approach has several advantages: The main shortcoming of this approach is that is not well suited to test applications that heavily rely on JavaScript. That said, if you are writing a traditional web application or an API then all the benefits mentioned above apply. For testing MVC applications we are going t...
