Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

What are the GitHub repositories or blogs to learn industry-standard coding for Web API
The eShopOnContainers is pretty popular, have you seen it yet? https://github.com/dotnet-architecture/eShopOnContainers

Message queues in microservices (eShopOnContainers example)
so I was exploring eShopOnContainers a little bit, more specifically the messages queues part and it made me wonder how is it possible to ensure data consistency across microservices when using them. If I'm not mistaken this isn't even shown in the eShopOnContainers examples.

Best practices for organising Mock Data & Repositories in Testing
For an example of an aggregate if you're unfamiliar - https://github.com/dotnet-architecture/eShopOnContainers/blob/3169a933447f1013c069e2cad2805c5de1ce9fbf/src/Services/Ordering/Ordering.Domain/AggregatesModel/OrderAggregate/Order.cs

App for Conferences
You can check out eShopOnContainers as a reference architecture if you want, but (assuming this is meant to be somewhat of an ad hoc solution rather than a paragon of software engineering) I'd minimize the number of deployable assemblies (1 + tests if possible) and avoid Docker, again unless you have a specific reason to use it.

Any simple microservice example using RabbitMQ?
For K8s, it has a whole directory with deployment scripts. https://github.com/dotnet-architecture/eShopOnContainers/tree/dev/deploy/k8s

Design question after the "Autommaper hate" post today
Checked the eshop on containers which uses EF for writes with DDD. Queries uses Dapper with raw sql. https://github.com/dotnet-architecture/eShopOnContainers/blob/dev/src/Services/Ordering/Ordering.API/Application/Queries/OrderQueries.cs

Small or medium sized open-source microservices
Maybe Microsoft’s eShopOnContainers reference system?

The Monad Invasion - Part 2: Monads in Action!
You probably noticed that .SetName() returns a Either. You may have come across Unit in libraries like MediatR or Language-Ext. It's a simple construct representing a type with only one possible value. We use it as a placeholder for operations that do not return a value but may return another state. In our example, .SetName() is a Command that does not return a value but may fail. Therefore, the monad Either carries two possible states: Right (without value) or Left (with an Error).

How small is the smallest .NET Hello World binary?
The widely used MediatR library[0] could be used to do that as well, just FYI.

CQRS: How to handle duplicate queries inside a CommandHandler

Easiest way to build the fastest REST API in C# and .NET 7 using CQRS
I gave it a go and I was impressed how easy and fast it was to set it all up. Since I'm not a big fan of REPR pattern almost all my projects are using CQRS pattern with a help of MediatR ](https://github.com/jbogard/MediatR) I immediately started going over something similar that Fast Endpoints offer which is a command bus.

MVVM Question: How do you manage the interaction between Model and ViewModel?
I'd use a dedicated event bus based on Reactive Extensions or MediatR to publish domain events from your domain services. This probably doesn't solve all your ViewModel update problems as is, maybe you need to revise the granularity (maybe you can have smaller ViewModels that refresh single property that exposes the Model) and lifespan (sometimes you can create a ViewModel, make it perform it's task and then discard it completely) of your ViewModels.
-
Async Methods after setting a property.
If you're finding yourself in a situation where you need to turn this behavior into a pattern because there are a lot of View Models that need to execute async business logic in response to some changes, I'd go with something like MediatR or Reactive Extensions. The idea is, again, that some other, probably business-level, component listens to changes in a decoupled way (that means it doesn't subscribe directly to your View Model, but to an event bus instead). View Model publishes change events to the event bus, and business-component reacts to these events by executing the business logic.

I don't get why I should use Redux
What people really want is to design the logic of an app independently from the component hierarchy. That means you need to store state somewhere other than the components and you need to dispatch events that are not attached to the component hierarchy. Also, a one way data flow has well known benefits as described by things like CQRS, RabbitMQ, and MediatR.
