Improve the startup time of your .NET Core application

Starting from .NET Core 3.x tiered compilation is enabled by default. This allows you to use precompiled code from assemblies created using the ReadyRoRun(R2R format. R2R is a form of ahead-of-time (AOT) compilation.

It improves startup performance by reducing the amount of work the just-in-time (JIT) compiler needs to do as your application loads.

To use this feature you need to enable ReadyToRun and publish your application as a self-contained app.

  1. Add the <PublishReadyToRun> setting to your project:

    <PropertyGroup>  
       <PublishReadyToRun>true</PublishReadyToRun>
    </PropertyGroup>

  2. Publish a self-contained app. Here is an example targetting the Linux ARM64 runtime:

    dotnet publish -c Release –r linux-arm64 --self-contained

Help! I accidently enabled HSTS–on localhost

I ran into an issue after accidently enabling HSTS for a website on localhost. This was not an issue for the original website that was running in IIS and had a certificate configured. But when I tried to run an Angular app a little bit later on http://localhost:4200 the browser redirected me immediately to https://localhost . Whoops! That was not what I wanted in this case. To fix it, you need to go the network settings of your browser, there are available at: chrome://net-internals/#hsts edge://net-internals/#hsts brave://net-internals/#hsts Enter ‘localhost’ in the domain textbox under the Delete domain security policies section and hit Delete . That should do the trick…
