Getting up to speed with QuickApp, an ASPNET Core / Angular4 startup project template

I’m always disappointed to see the amount of work to get your application setup done(you know the typical ‘Sprint 0’ work). Creating your frontend and backend projects, setting up your authentication and authorization, configure the webpack magic and so on… Before you know it you are 2 weeks in your project and you didn’t deliver a single bit of business functionality.

So every tool, framework or library that can help you get up to speed is a welcome addition to our toolbox. Recently I discovered QuickApp, an ASP.NET Core/AngularX Project Template.

QuickApp Demo

From the documentation:

This application consists of:

  • Template pages using Angular4 and TypeScript
  • RESTful API Backend using ASP.NET Core MVC Web API
  • Database using Entity Framework Core
  • Authentication based on OpenID Connect
  • API Documentation using Swagger
  • Webpack2 for managing client-side libraries
  • Theming using Bootstrap

You get the benefits of:

  • A complete backend and frontend project structure to build on, with login, user and permission-based role management already integrated
  • Data Access Layer built with the Repository and Unit of Work Pattern
  • Code First Database
  • A RESTful API Design
  • Angular Directives Quidance
  • Angular Pipes Quidance
  • Angular Animations Quidance
  • Angular Services
  • Dialog and Notification Services
  • Configuration Page and Configuration Service
  • Integrated Internationaliztion
  • Theming with SASS
  • Ready-to-use email API
  • Handling Access and Refresh Tokens with WebStorage (Bearer authentication) - No Cookies
  • Jquery Integration (Ability to use standard Jquery libraries)
  • CRUD APIs

Podman– Command execution failed with exit code 125

After updating WSL on one of the developer machines, Podman failed to work. When we took a look through Podman Desktop, we noticed that Podman had stopped running and returned the following error message: Error: Command execution failed with exit code 125 Here are the steps we tried to fix the issue: We started by running podman info to get some extra details on what could be wrong: >podman info OS: windows/amd64 provider: wsl version: 5.3.1 Cannot connect to Podman. Please verify your connection to the Linux system using `podman system connection list`, or try `podman machine init` and `podman machine start` to manage a new Linux VM Error: unable to connect to Podman socket: failed to connect: dial tcp 127.0.0.1:2655: connectex: No connection could be made because the target machine actively refused it. That makes sense as the podman VM was not running. Let’s check the VM: >podman machine list NAME         ...

Cache stampede: when our cache turned against us

While investigating some performance issues, we ran into an ASP.NET Core API that cached a fairly expensive aggregation query for 60 seconds. Under normal load, that was fine: one request rebuilds the cache, everyone else reads from it. Under peak load, dozens of requests would arrive in that same expiry window, all see a cache miss, and all fire the same expensive query in parallel. The database didn't like that. That was the moment when our caching layer stopped helping and started hurting. A burst of requests comes in at the same time, all miss the cache, and all go hammer the database or the downstream API at once. That's a cache stampede . The cache was supposed to protect our backend, and for a few hundred milliseconds it did the opposite. Why this happens IMemoryCache.GetOrCreate (and its async sibling) looks like it protects you, but it doesn't add any locking on its own. Look at the naive version: public async Task<Report> GetReportAsync(string key) ...

The role of ActivitySource in OpenTelemetry for .NET

While doing some pair programming to integrate OpenTelemetry tracing to a .NET application, we had a discussion on how to use the ActivitySource . It looks simple. You new one up, give it a name, start an activity, done. The discussion started when we added a second ActivitySource with the exact same name in a different class. This made us wonder: "Are we duplicating traces now? Is this a memory leak? Do we need a singleton?" So we decided to dig deeper. This post is what we learned… What ActivitySource actually is ActivitySource is part of System.Diagnostics , not part of the OpenTelemetry NuGet packages. Microsoft built tracing primitives directly into the BCL, and OpenTelemetry's .NET SDK simply listens to them. This is why you can add distributed tracing to a library without taking a dependency on OpenTelemetry at all. An ActivitySource is a factory for Activity objects, and an Activity is .NET's name for what OpenTelemetry calls a span.(don’t ask m...
