About C# BASH Sample

The example code here references Docker and IoT Edge as an example. The user/pass is Base64 encoded as part of the Bash class in this example.

By no means should you keep the admin user/pass hard-coded in the production class, this is an example piece.

What's The Difference?

The Bash class has both RunAs(..) and Command(..), and each allows you to run using sudo. The difference is, the RunAs(...) method does not require your app to be started with elevated privledges. Where as, Command(..) requires you to start the app with elevated privledges in order to execute commands using sudo.

When developing in medium to larger teams, becomes more important to be able to automatically maintain code styling throughout the project to maintain readability and clarity. This rule also applies to smaller projects as well, abiet at times easier to manage ("New guy, please remove the 5 blank lines in a row in the method. And the blank spaces after the statements.").

Below is a quick snip for configuring VSCode to automagically take care of this every time you press save (Ctrl+S). The following assumes you already have a project workspace already started in VSCode.

TL;DR Configuration

Key files:

.vscode/extensions.json
.vscode/settings.json

Remove .NET From Linux

This document outlines steps for performing a deep clean on your Linux (Ubuntu 20.04) machine.

An example for performing could be, if your installation does not show in dotnet --list-sdks. Performing this deep clean and reinstalling will solve it in most cases.

Install

wget https://packages.microsoft.com/config/ubuntu/20.04/packages-microsoft-prod.deb -O packages-microsoft-prod.deb

C# - Awaiting Task with Timeout

Source Article

Scenerio, you have an awaitable object and you want to await it with a timeout. How would you build that?

What you can do is use a when_any-like function in combination with a timeout coroutine. For C# this would be something like

await Task.WhenAny(

	<UserControl.Resources>
	<ResourceDictionary>
	<DataTemplate x:Key="FlatDeviceInfo" DataType="models:DeviceInfo">

	<MultiBinding StringFormat="{}{0} - {1}">
	<Binding Path="Address" />
	<Binding Path="DeviceTypeName" />
	</MultiBinding>
	</TextBlock.Text>
