How To Do Logistic Regression Using ML.NET

Microsoft Research's Dr. James McCaffrey show how to perform binary classification with logistic regression using the Microsoft ML.NET code library. The goal of binary classification is to predict a value that can be one of just two discrete possibilities, for example, predicting if a person is male or female

Writing the Code for a gRPC Service and Client in ASP.NET Core 3.0

Once you've got a contract that describes a gRPC service, creating the service itself and a client that can call the service is easy. In fact, Visual Studio will do most of the work for you ... once you've got your projects set up correctly, that is.

Defining Your First gRPC Service in an ASP.NET Core 3.0 Project

gRPC services promise a lot: better performance, more sophisticated messaging, and a contract-based approach to Web Service development. If those sound good to you, here's how to get started.

Two 'Gotchas' (and Fixes) for Blazor in .NET Core 3.0

The release version of Blazor contains two surprising changes (surprising, at least, to Peter) -- changes that broke some of his code. Here are both of those "gotchas" with the workarounds that he implemented.

Getting Started with AutoML for ML.NET

Dr. James McCaffrey provides hands-on examples in introducing ML.NET, for machine learning prediction models, and AutoML, which automatically examines different ML algorithms, finds the best one, and creates a Visual Studio project with the C# code backing the best model, along with C# code that shows how to use the trained model to make a prediction.

Decrypting (But Not Really Encrypting) Configuration Settings in ASP.NET Core

You can store encrypted values in your ASP.NET Core configuration file and seamlessly decrypt the values as you retrieve them. But there are, at least, two issues that you'll need to address.

How to Integrate Blazor Components

You can create Blazor components by combining other Blazor components but you'll almost certainly need to share data between those components. Here are all the options currently open to you.

What Are gRPC Web Services and When Should I Use Them?

ASP.NET Core allows you to create Web Services based on gRPC ... which raises two questions: "What is gRPC?" and "Does it ever make sense to use it?" Here are Peter's answers.

Agile Development: How to Pick the Most Valuable User Stories

Some of the critical problems for any team working in an Agile way are managing the backlog of user stories, converting epics into stories, preventing scope creep, and -- most importantly -- picking the most valuable stories for the next sprint. Impact mapping provides a visual solution for all these issues.

How to Update Members of a Collection with LINQ

Sometimes it's just cool to take a walk through some technology to find all the different ways you can solve a problem -- sort of "Fun with the .NET Framework." Here's a look at all the ways that Peter could think of to update an object in a collection ... some of which may be foolish.

How To Code Modern Neural Networks Using Python and NumPy

Data scientist Dr. James McCaffrey begins a series on presenting and explaining the most common modern techniques used for neural networks, for which over the past couple of years there have been many small but significant changes in the default techniques used.

The Service Layer in Software Development Doesn't Exist

While the concept of "service classes" probably has some value when it comes to organizing the objects you're dealing with, the idea of a "service layer" has no value at all when it comes to building applications.

How to Do Thompson Sampling Using Python

Suppose you have three different Internet advertising strategies and you want to determine which of them is the best as quickly as possible. Or suppose you work for a medical company and you want to determine which of three new drugs is the most effective. Resident data scientist Dr. James McCaffrey shows how Thompson Sampling can help.

How to Dynamically Build the UI in Blazor Components

You have two tools for generating your initial UI in a Blazor component: ASP.NET's Razor and Blazor's RenderFragment. Here's how to use both to integrate with your C# code (and a warning about what you can't do).

Creating a Custom Tag Helper in ASP.NET Core: Generating HTML

The beauty of a tag helper is it's ability to add new HTML to your page. Once you know what you want to change, here are the tools to change the HTML going to the user.

Creating a Custom Tag Helper in ASP.NET Core: Gathering Data

You can create your own custom tag helpers ... but it's a lot easier if you understand the process that tag helpers need to go through. Here are your options when gathering the data that a tag helper needs (and why they can't completely replace HtmlHelpers).

The Fundamentals of Improving Productivity with Custom Tag Helpers in ASP.NET Core

Whenever you have repeated HTML, you should be creating your own tag helpers to simplify your views. Here's how flexible tag helpers can be when you go to integrate them into your page.
