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.

How to efficiently call an arbitrary method?
There are some libraries which allows you to declare some class with more or less arbitrary methods which will be called by it at runtime. I believe many of them do that in optimal way, not just using usual reflection. One of the examples is HotChocolate library https://github.com/ChilliCream/hotchocolate . You declare class with arbitrary methods which contain arbitrary arguments. "Arbitrary" doesn mean arbitrary at all, but if parameter type is registered in DI or marked by specific attribute, it can be passed to the method.

ChilliCream GraphQL vs GraphQL.Net in
At work we are considering using GraphQL to build our read-only data-APIs using .NET 6, EF Core and SQL Server. Looking at the ecosystem the most relevant plattforms seems to be graphql-dotnet and ChilliCream.

Graphql-dotnet vs Hot Chocolate, which one to choose?
I'm starting a brand new project. Looks like if we want to do GraphQL in .NET, it's either graphql-dotnet or Hot Chocolate. Both look pretty good on paper.
- GraphQL is quickly moving to one of my least favorite technologies

JavaScript: *gets annihilated*
If you know it better: Please try statically typed generated graphql queries in C# (like write the graphql queries, have a graphql schema, then get generated C# types which resemble the query, the only thing I've found that could do it was https://chillicream.com/docs/strawberryshake and there I quickly hit this bug with super simple queries containing unions: https://github.com/ChilliCream/hotchocolate/issues/4662

Which programming language, besides JS, has the best support/ecosystem for graphql?
I love using Hot Chocolate in C# ❤

GraphQL mutation union erros (6a) with Hotchocolate GraphQL Server
Hotchocolate GraphQL server. This is the most advanced server for a .Net environment. This article does not go into the basics and assumes some framework knowledge.

Introducing pf2e.io, a generic, source-available, re-usable and most notably free set of services for creating pathfinder 2e tools, sites and applications.
I think for the time being that's the case, yeah. I'm confirming with the great people over at https://github.com/ChilliCream/hotchocolate to see if we can somehow work around that.

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.
