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.

Working with Dapper/SQL-Server Framework 4.8 C#
In both samples to get all records and to get a single record works fine but there is a better way to perform the same work using NuGet package Dapper. Dapper is extremely easy to use and built with performance in mind. In the source code provided the basic operations are covered, to take things to the next level and read the information at GitHub, the following page and other code samples in the following repository.

Working with Dapper in C#
In this article learn how to use Dapper an open-source object-relational mapping (ORM) library for .NET and .NET Core applications. Unlike many articles out there, this one will provide source code to try everything out that is shown in an easy-to-follow way by beginning with a single table then in part two of this series will work with multiple tables.

REST API using C# .NET 7 with MySql
I will be using Dapper - a simple object mapper for .Net along with MySqlConnector.

Resources for learning minimal API using dapper in .net
Maybe the more basic approach to dapper is their documentation https://github.com/DapperLib/Dapper the readme but again most likely you not gonna understand

SQL Connection Question
I think EF Core & EF are the successors to LINQ to SQL that you'd wanna look into, and/or Dapper if you wanna go lower.

Dapper is die?
The main maintainers of Dapper no longer work at Stack, but they're active enough to comment on recent pull requests: https://github.com/DapperLib/Dapper/pull/1887.

- Discriminated Unions: Essa feature faz falta no CSharp

DevDocs
Certain parts of Microsoft Learn are permissive, for example the .NET BCL documentation is Creative Commons Attribution: https://github.com/dotnet/dotnet-api-docs as is ASP.NET Core: https://github.com/dotnet/AspNetCore.Docs (a good hint if documentation is permissively licensed and on GitHub is if there's an edit button at the top.)
The C# language specification is unfortunately a bit fuzzier: https://github.com/dotnet/csharplang/discussions/4855
The updated unified C# language specification is CC, but it's still catching up to modern C#: https://github.com/dotnet/csharpstandard

The golden age of Kotlin and its uncertain future
No OP, but for example you still see the C# folks still struggling to add discriminated unions to the language because of complex interactions due to its too many features[1]. Virtual threads are easier to use than async/await is another example.

When static types make your code shorter
For example, C# had a research fork called Spec# that had compile-time support for contracts, with keywords such as requires (for arguments) and ensures (for return values), all the way back in 2004. While still being discussed, it doesn't seem to be shipping any time soon.

.NET 8 – .NET Blog
Hi there. I'm the language designer who created the 'Collection Expression' design/specification: https://github.com/dotnet/csharplang/issues/5354
You can see the entire history of the proposal there. To answer you specific question, we went with `..` because that's what the language already uses for the complimentary 'pattern matching deconstruction' form for collection patterns.
In other words, you can already say this today:
if (x is [var start, .. var middle, .. var end]) { ... }

What's new in C# 12: overview
You must specify concrete type.
There was a plan to have "natural type" so "var list = [1,2,3]" would be of type "List" but it was postponed to C# 13 (https://github.com/dotnet/csharplang/issues/5354#issuecommen...)

Robust Design through Value Objects in C#
While C# currently lacks direct support for this kind of functionality, there's a glimmer of hope with an active proposal under discussion that aims to bring this feature to the language. This potential addition promises a future where C# can natively offer similar robust type narrowing.
-
The combined power of F# and C#
Given few people anticipated ValueTuple and C# adding a more direct tuple syntax, I feel like it is only a matter of time before C# adds discriminated unions.
(There are multiple proposals tracking the idea. This seems the most comprehensive and "central": https://github.com/dotnet/csharplang/issues/7016)

Should i quit Django and move to asp.net
I always liked list abbreviations in python, but I absolutely love Linq. I believe there is a feature proposal for C# 12, which makes collection initialization better imo.
