Top 23 C# Database Projects
-
Entity Framework
EF Core is a modern object-database mapper for .NET. It supports LINQ queries, change tracking, updates, and schema migrations.
An attribute is new. Github issue.

Project mention: What sort of mature, open-source libraries do you feel Rust should have but currently lacks? | reddit.com/r/rust | 2021-11-01
A mature NoSQL embedded/flatfile database like LiteDB would be nice. There are some similar Rust libraries but they aren't very close to production ready and the API tends to not be too user friendly. I had trouble finding one of these for a small app I had to write recently.

Scout APM
Less time debugging, more time building. Scout APM allows you to find and fix performance issues with no hassle. Now with error monitoring and external services monitoring, Scout is a developer's best friend when it comes to application development.
-
Bogus
:card_index: A simple fake data generator for C#, F#, and VB.NET. Based on and ported from the famed faker.js.
Or check out something like Bogus for generating fake data.
-
Where's the catch, then? Well, there's a couple of catches, in fact. First of all, in a distributed setting, appending data to a log isn't that easy. First, you need to make your log distributed. Again, Kafka/Cassandra/EventStore make this possible, however, whenever you start dealing with distributed data, you‘re introducing new operational and implementation complexity.

Personally I prefer to use FluentMigrator to schema modification data load.

Project mention: people who use Linux for using C# at your job, what is your role, and does Linux suit your needs? | reddit.com/r/csharp | 2021-12-11
But our production server was Linux. Windows Server and Linux servers are both very capable, but Linux does the same job without any license fee. We also used Postgres for our database (again free) and it turned out that the EF Core provider of Postgres has more capabilities than the SQL Server one!
-
SonarQube
Static code analysis for 29 languages.. Your projects are multi-language. So is SonarQube analysis. Find Bugs, Vulnerabilities, Security Hotspots, and Code Smells so you can release quality code every time. Get started analyzing your projects today for free.

Ahhh, I know that Entity Framework would do this at one point, IDK if EF Core does or not.
Linq2Db does it via T4 Template generation, so you can play with it more if you want [0]

SqlKata Query Builder
SQL query builder, written in c#, helps you build complex queries easily, supports SqlServer, MySql, PostgreSql, Oracle, Sqlite and Firebird
Not really an ORM. But I have been enjoying SqlKata recently. Works with Dapper but helps reduce SQL strings and makes things like pagination really easy. Also nice for dynamic filters.

Pomelo.EntityFrameworkCore.MySql
Entity Framework Core provider for MySQL and MariaDB built on top of MySqlConnector

Project mention: Considering MongoDB for a Production ERP System with Net 6 | reddit.com/r/csharp | 2022-01-23
You can use Marten for this with Postgres. https://martendb.io/

Entity Framework 6
This is the codebase for Entity Framework 6 (previously maintained at https://entityframework.codeplex.com). Entity Framework Core is maintained at https://github.com/dotnet/efcore.
Project mention: Ask HN: What tangible benefits did you get from spending time on HN? | news.ycombinator.com | 2021-03-06Every so often, posts from Bruce Dawson's blog get posted here - one such post was about using Event Tracing for Windows to diagnose an issue with an NTFS lock being held causing 63 cores to idle while 1 does all the work.
https://randomascii.wordpress.com/2019/10/20/63-cores-blocke...
A few months later, some other people in my team were struggling to diagnose an issue in production where a legacy webapp was struggling to scale up and fully use all 64 cores of the server we needed it to run on. I stepped in to help and remembered that post I'd seen on HN. We used ETW (through Windows Performance Recorder and Windows Performance Analyzer) to profile our app and I looked into the Wait Analysis. Turns out that Entity Framework 6 uses a ReaderWriterLockSlim to guard a cache, and that particular lock performs extremely poorly under heavy contention. Heavy in our case meant that for a single page build of one of this app's "hot path" pages, this lock would be taken a few hundred thousand times. We weren't the first to discover this:
https://github.com/dotnet/ef6/issues/1500
What some other people in my team were struggling with for about two weeks was resolved in a single day thanks to me goofing off and reading HN. (We ultimately used a fork of EF6 that didn't suffer from this issue to solve our problem)

Project mention: Offline Sync - What are the current options | reddit.com/r/xamarindevelopers | 2021-05-26
I'm also looking into a local DB for storage and am looking at Realm (Xamarin example).

NPoco
Simple microORM that maps the results of a query onto a POCO object. Project based on Schotime's branch of PetaPoco

Project mention: Alguna alternativa a MSSQL que no sea MySQL o PostgreSQL | reddit.com/r/CharruaDevs | 2021-06-05
Sólo he usado el protocolo de Cassandra desde Go, pero por lo que veo para .NET en vez de pagar por eso usaría el driver de DataStax que implementa el mismo protocolo y es open source: https://github.com/datastax/csharp-driver

Project mention: Suggestions for how to implement this real-time app? | reddit.com/r/webdev | 2021-05-27

DBreeze
C# .NET MONO NOSQL ( key value store embedded ) ACID multi-paradigm database management system.

Project mention: any good binary serializers that are not assembly dependent | reddit.com/r/csharp | 2021-10-23
So the answer is no, there aren't. If you want to add that kind of security risk to your application you can use ceras
