Using ML.NET for deep learning on images in Azure

Luis QuintanillaMay 6, 2020May 6, 202005/6/20

This post will show you how to train a custom image classification model in Azure to categorize flowers using ML.NET Model Builder. Then, you can leverage your existing .NET skills to consume the trained model inside a C# .NET Core console application. Best of all, little to no prior machine learning knowledge is required.

Introducing C# Source Generators

Phillip CarterApril 29, 2020Apr 29, 202004/29/20

We're pleased to introduce the first preview of Source Generators, a new C# compiler feature that lets C# developers inspect user code and generate new C# source files that can be added to a compilation. This is done via a new kind of component that we're calling a Source Generator. To get started with Source Generators, you'll need to inst

Help us shape the future of deep learning in .NET

Brigit MurtaughApril 21, 2020Apr 21, 202004/21/20

Deep learning is a subset of machine learning used for tasks such as image classification, object detection, and natural language processing. It uses algorithms known as neural networks to learn and make predictions on image, sound, or text data. Neural networks learn from experience, just like we do as humans. Similar to how we may try an

Regex Performance Improvements in .NET 5

Stephen Toub - MSFTApril 2, 2020Apr 2, 202004/2/20

For .NET 5, we’ve invested in some significant improvements to the Regex engine. On many of the expressions we’ve tried, these changes routinely result in throughput improvements of 3-6x, and in some cases, much more. In this post, I’ll walk through some of the myriad of changes that have gone into System.Text.RegularExpressions in .NET 5.
