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.

    • Project mention: Runtime code generation and execution in Go | news.ycombinator.com | 2024-05-29

    This looks like a fun project but for serious work, if you need runtime codegen, you should use .NET which has been successfully using reflection and IL emit for more than a decade:

    - Regex https://github.com/dotnet/runtime/blob/main/src/libraries/Sy...

    - Json https://github.com/neuecc/Utf8Json/tree/master?tab=readme-ov... (this project is archived but nonetheless impressive and continues to show good numbers despite obsoletion)

    - LINQ to DB query compilation https://github.com/dotnet/efcore/blob/main/src/EFCore/Query/...

  • Bogus

    :card_index: A simple fake data generator for C#, F#, and VB.NET. Based on and ported from the famed faker.js.

    • Project mention: Bogus custom Dataset | dev.to | 2024-01-06

    Bogus NuGet package is fake data generator which can be helpful for populating tables in a database and testing purposes. If a database is not used and Bogus populates list of data each time an application runs, the data is random, never the same. Also, the random data generated by Bogus may not meet a developer’s requirements.

  • InfluxDB

    Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.

  • LiteDB

    LiteDB - A .NET NoSQL Document Store in a single data file

    • Project mention: Local migrations for embedded SQLite in F# | dev.to | 2024-03-02

    Personally, I used to use LiteDB which is a NoSQL version which in v4 paired very nicely with F# thanks to Zaid's lovely LiteDB.FSharp library. Sadly, when v5 showed up, a lot of the F# niceties were lost given how the API was changed and v5 was not very F# friendly. You can still use it of course but you fall back to more unsafe F# code which is not ideal.
