NetLearner: What is it?

NetLearner is an ASP .NET Core web app to allow any user to consolidate multiple learning resources all under one umbrella.

Some Background: As I’ve been doing a lot of R&D on ASP .NET Core, I found myself keeping track of blog posts, podcasts, YouTube videos, Twitch streams, Pluralsight tutorials, ebooks across Amazon, Safari Books Online, and so much more. I’ve been using Notepad, OneNote, browser bookmarks, Twitter lists, emails to myself, Google/Word docs and so much more just to keep track of URLs, notes and progress. I’m building this new app for myself to organize my learning plans, but also open-sourcing it and deploying it to allow others to use it too.

Web NetLearner on GitHub: https://github.com/shahedc/NetLearner

The name implies 2 things: the app’s source code will be a real-world example for people learning .NET (specifically ASP .NET Core 2.1 and beyond), and the tool itself will help people learn any topic from various resources across the Internet.

What can you expect in 2019?

  1. Use the web app’s source code to learn all about ASP .NET Core 2.1+ and beyond.
  2. Add links to various learning resources: books, articles, blogs, conference sessions, podcasts, online workshops, videos and livestreams.
  3. View embedded content where appropriate, e.g. videos
  4. See contents of RSS feed where appropriate, e.g. blogs with RSS
  5. Discover what others have added to their NetLearner lists, via suggestions of what’s popular.
  6. Follow content creators with links to their social media accounts.
  7. Deploy your own instance instantly to your own Azure account.
  8. Build lists to learn anything and share with others.

Stay tuned for more information!

Your Web App Secrets in ASP .NET Core

This is the fifth of a new series of posts on ASP .NET Core. This week, we’ll be looking  at app secrets for ASP .NET Core projects, for use in development environments.

Protecting Application Secrets During Development

Most web apps need to store some configuration information that can be accessed by the application during runtime. This may include database connection strings and API keys, which are not user-specific confidential values, but are still sensitive pieces of information that need to be protected.

Once in a while, a developer may accidentally commit such sensitive information to public repositories such as Github. Quoting this blog post from the Azure website, “Keep in mind that removing a published secret does not address the risk of exposure. The secret may have been compromised, with or without your knowledge and is still exposed in Git History. For these reasons, the secret must be rotated and/or revoked immediately to avoid security risks.”

This blog post intends to prevent you from ever making that mistake in the first place. You may download the following sample project to follow along.

This is the third of a new series of posts on ASP .NET Core. This week, we’ll be looking at various types of Pages you may encounter in an ASP .NET Core web app:

  1. Razor Pages (new as of v2.0)
  2. the experimental Blazor (C# in the browser!)
  3. the more familiar MVC Views (aka Razor Views)

If you already know how to create each type of project, feel free to jump past section 3B below.

Before you begin

Before you begin, make sure you download an IDE or code editor to open and run the code samples. My recommendations are below:

A. Visual Studio Code: https://code.visualstudio.com

B. Visual Studio 2017 (v15.8 or later): https://visualstudio.microsoft.com/vs/

To use Blazor in Visual Studio 2017, you must install the ASP .NET Core Blazor Language Services extension from the Visual Studio Marketplace:

Web Blazor extension: https://marketplace.visualstudio.com/items?itemName=aspnet.blazor

The instructions below will cover both Command Line Interface (CLI) commands and IDE/editor steps to create, build and run the code samples.

This is the second of a new series of posts on ASP .NET Core. In the past week, I had the opportunity to participate in a hackfest with several colleagues from across the globe, to work on real-life customer projects. I took a break from my primary project to help a colleague with a simple problem: upload a file from a web browser and save it into Azure Blob Storage within an ASP .NET Core web application!

Before you begin

Before you begin, make sure you sign in to Azure, create a storage account and make a note of the storage connection information.

Refer to:

“Show me the code!”

Fortunately, I packaged everything nicely as a simple web app project, uploaded into Github and added instructions on how you can use it right away.

Web Get it here: https://github.com/shahedc/SimpleUpload

I tested it in Visual Studio 2017 v15.8.6 and Visual Studio Code, so either should work for you.

It’s been a while since I wrote a new blog post besides event announcements and posting slides so here’s the first of a new series of posts. The topic: ASP .NET Core!

Why ASP .NET Core?

With all the things I’ve been working with lately, I’ve still kept up to date on what’s new with ASP .NET Core for building Web Apps, Web APIs and even full-stack C# web applications with Blazor!

With the release of ASP .NET Core 2.1, and the upcoming releases of 2.2 (late 2018) and 3.0 (2019), now is a great time to be an ASP .NET Core developer. But where should you begin? You have many options.

Dev Tools for ASP .NET Core

  1. Visual Studio for Windows: a full-fledged IDE that runs on Windows (or even on Windows on your Mac via Parallels/Bootcamp. Get the latest version to try out new stable ASP .NET features and get the Preview versions to try cool new features. Install just the pieces you need. Start with the free Community edition for students, individuals and open-source projects.
  2. Visual Studio for Mac: build ASP .NET Core applications on a Mac in a full-fledged IDE. VS for Mac can also be used for macOS apps, Xamarin mobile apps for iOS/Android, cloud apps and more!
  3. Visual Studio Code: super light-weight code editor available on Windows, MacOS and Linux. Use the dotnet CLI tools in the integrated Terminal to quickly build ASP .NET Core web apps and more!
