Modernizing a codebase for C# 9

There are lots of cases that you can improve. The examples use nullable reference types, but only the WhenNotNull example requires it.

Use the property pattern to replace IsNullorEmpty

Consider adopting the new property pattern, wherever you use IsNullOrEmpty.

string? hello = "hello world";

Preserving State in Server-Side Blazor applications

Server-side Blazor is a stateful application framework. Most of the time, your users will maintain an ongoing connection to the server, and their state will be held in the server's memory in what's known as a "circuit". Examples of state held for a user's circuit include:

• The UI being rendered (i.e., the hierarchy of component instances and their most recent render output)
• The values of any fields and properties in component instances
• Data held in DI service instances that are scoped to the circuit

Occasionally, users may experience a temporary network connection loss, after which Blazor will attempt to reconnect them to their original circuit so they can continue.

Active Directory Authentication

This will provide an example of integrating Active Directory authentication in an ASP.NET Core app.

Note, you'll need to be running on a Windows domain with Visual Studio debugging in IIS Express for this to work.

Setup

In launchSettings.json, you'll want to modify iisSettings by turning on windowsAuthentication:

$cmdbar_name = 'ReSharper (Custom)'
$ctrl_caption = 'Toggle ReSharper'

$cmdbar = $DTE.CommandBars[$cmdbar_name]
if (-not $cmdbar) {
    Write-Host "Creating '$cmdbar_name' toolbar..."
    $cmdbar = $DTE.Commands.AddCommandBar($cmdbar_name, [EnvDTE.vsCommandBarType]::vsCommandBarTypeToolbar)
}

if (-not ($cmdbar.Controls | Where-Object Caption -eq $ctrl_caption)) {
