Hybrid Database Migrations with EF Core and Flyway

Julie Lerman

During development, it’s common to use EF Core migration commands to not only create migration files but to also execute migrations directly on your development database. But in production this isn’t the best idea. Learn to combine EF Core migrations and Flyway to create an explicit mechanism to perform migrations on a production database.

Accessing XML Documentation via Reflection


Accessing XML Documentation via Reflection

Zachary Patten

XML documentation on C#/F#/VB code isn’t included in the compiled code--it’s placed in a separate XML file. Because of this, you can’t normally access the documentation via reflection. However, with one loading function and a handful of extension methods on the reflection types, you can easily access the XML through reflection types.

Using gRPC in a Microservice Architecture

Dino Esposito

The gRPC framework shines when used in a server-to-server scenario and preferably when caller and service evolve as part of the same development cycle. Dino Esposito shows how gRPC can be a powerful solution for microservice architectures.

Neural Binary Classification Using PyTorch

James McCaffrey

The goal of a binary classification problem is to make a prediction where the result can be one of just two possible categorical values, such as predicting the sex of a person based on their age, annual income, and so on. In this article you’ll learn how to perform binary classification using a deep neural network with the PyTorch code library.
