Visual Studio 2019 Productivity Cheat Sheet

Several new time-saving keystroke combinations were recently detailed by Kendra Havens, program manager for .NET and Visual Studio, in a Channel 9 video presentation. Here's a roundup of the new stuff, along with old favorites, and a list of other productivity resources.

10 Top Blazor Tools Just a NuGet Away

The hottest NuGet extensions for the hottest ASP.NET Core project.

Integrating Blazor into Existing ASP.NET Core Applications

If you want to add server-side Blazor to your existing ASP.NET Core applications, you can. There's not much to it, fortunately. In fact, there's probably more work involved in creating a View or Page that will play well with your component

Naive Bayes Classification Using Python

Dr. James McCaffrey of Microsoft Research uses Python code samples and screenshots to explain naive Bayes classification, a machine learning technique used to predict the class of an item based on two or more categorical predictor variables, such as predicting the gender (0 = male, 1 = female) of a person based on occupation, eye color and nationality.

Blazor on the Server: The Good and the Unfortunate

Blazor on the Server is coming with .NET Core Version 3.0 in the second half of 2019. Here's what Peter thinks of that (and he's not completely happy).

ASP.NET Core Security, Part 1

Eric Vogel kicks off his series on ASP.NET Core security by showing how to set up authentication to register, log in and log out a user account in an ASP.NET Core MVC application.

Logging in .NET Core

.NET Core provides a framework that logging systems can be snapped into. However, what's most important about this framework is how you write your messages out. It's the quality of the message that will let you find where your problems are.

Working with Dynamic Objects: Beyond the Basics with ExpandoObjects

ExpandoObjects let you dynamically add members to your object at run time -- a great way to handle scenarios where you need a lot of flexibility. But how do you work with an object when you don't know the names of its properties?

5 Top, No-Cost .NET Core Extensions for Visual Studio 2019

Here are some of the top, free .NET Core-related extensions that target Visual Studio 2019.

Weighted k-NN Classification Using Python

Need to predict the political party affiliation (democrat, republican, independent) of a person based on their age, annual income, gender, years of education and so on? Our resident data scientist Dr. James McCaffrey shows a technique that can help with that and much more -- with code!

Making It Up as You Go Along with ExpandoObjects

You can give your users the ability to store any data they want, including stuff they make up at run time, by using an ExpandoObject. In fact, when you don't know what your data is until run time (and you can live without IntelliSense), an ExpandoObject is your best solution.

Managing Page Layouts in Blazor

Blazor, like most systems for generating Web pages, supports using layout pages for repeated content. Here's what works, what doesn't (yet) work and work-arounds I've discovered for what doesn't work.

Managing Production and Development Settings in ASP.NET Core

The reality is that you will need to have, at least, two different configurations: one for production and one for development. Here's how to automate those conversions.

Extending Razor Pages

If you move beyond the basics of working with Razor Pages, there are at least two things you should know to support creating Pages that do more than one thing and integrate with existing code.

Navigating in Blazor

If you're moving your application's client-side code to Blazor, then you'll want Blazor to manage navigating between pages, too.

Dealing with Databases (and Data) in Docker

There are lots of ways to handle databases in a containerized environment like Docker. Here's how to create SQL Server in a container, how to load it with the data you want and how to integrate that container into whatever project needs it. Be warned: Some PowerShell is used.

Docker with Real Applications

Here's how to run a "real-world" application (consisting of an MVC application and a Web Service) in a networked set of Docker containers. And it's just a couple of mouse clicks in Visual Studio to implement it.

Neural Anomaly Detection Using Keras

Our resident doctor of data science this month tackles anomaly detection, using code samples and screenshots to explain the process of finding rare items in a dataset, such as discovering fraudulent login events or fake news items.

Support Vector Machines Using Accord.NET

The Data Science doctor delves into supporting vector machines, software systems that can perform binary classification such as creating a model to predict the gender of a person based on their age, annual income, height and weight.

Building Razor Pages

If you want to handle the most common pattern in ASP.NET Controllers (displaying a page and then accepting data entered into it), you can do it with Razor Pages. You'll just need less code than if you used a Controller, a View and a model object.
