Perst
Perst is McObject’s open source, dual license, object-oriented embedded database system (ODBMS). It is available in one edition developed as an all-Java embedded database, and another implemented in C# (for Microsoft .NET Framework applications). Perst gives developers the ability to store, sort, and retrieve objects in their applications with maximum speed and with low memory and storage overhead while leveraging the object-oriented paradigm of Java and C#. In the TestIndex and PolePosition benchmarks, Perst displays one of its strongest features: its significant performance advantage over Java and .NET embedded database alternatives. Perst stores data directly in Java and .NET objects, eliminating the translation required for storage in relational and object-relational databases. This boosts run-time performance. Perst’s core consists of only five thousand lines of code. The small footprint imposes minimal demands on system resources.

Entity Framework Core
Entity Framework (EF) Core is a lightweight, extensible, open source and cross-platform version of the popular Entity Framework data access technology. Enables .NET developers to work with a database using .NET objects. Eliminates the need for most of the data-access code that typically needs to be written. With EF Core, data access is performed using a model. A model is made up of entity classes and a context object that represents a session with the database. The context object allows querying and saving data. Generate a model from an existing database. Hand code a model to match the database. Once a model is created, use EF migrations to create a database from the model. Migrations allow evolving the database as the model changes. Instances of your entity classes are retrieved from the database using Language Integrated Query (LINQ). Data is created, deleted, and modified in the database using instances of your entity classes.
