    KeePass

    KeePass

    A lightweight and easy-to-use password manager

    KeePass Password Safe is a free, open source, lightweight, and easy-to-use password manager for Windows, Linux and Mac OS X, with ports for Android, iPhone/iPad and other mobile devices. With so many passwords to remember and the need to vary passwords to protect your valuable data, it’s nice to have KeePass to manage your passwords in a secure way. KeePass puts all your passwords in a highly encrypted database and locks them with one master key or a key file. As a result, you only have to remember one single master password or select the key file to unlock the whole database. And the databases are encrypted using the best and most secure encryption algorithms currently known, AES and Twofish. See our features page for details.

    The stream database optimised for event sourcing

    Persist your application data as streams of events with our open-source database, the best data storage solution for event-sourced systems. Available for free download on most platforms or use our managed service Event Store Cloud. EventStoreDB is an open-source database technology that stores your critical data in streams of immutable events. It was built from the ground up for Event Sourcing, we believe that makes it the best solution in the market for building event-sourced systems. Event Sourcing offers some great benefits over state-oriented systems; the key ones are explained below. An event-sourced system stores your data as a series of immutable events over time, providing one of the strongest audit log options available. All state changes are kept, so it is possible to move systems backward and forwards in time which is extremely valuable for debugging and “what if” analysis.

    Entity Framework 6

    Entity Framework 6

    This is the codebase for Entity Framework 6

    Entity Framework 6 (EF6) is a proven object-relational (O/RM) mapper for .NET with many years of feature development and stabilization. Like O/RM, EF6 reduces the impedance mismatch between the relational and object-oriented worlds, allowing developers to write applications that interact with data stored in relational databases with strongly typed .NET objects that represent the domain of the database. application, and eliminate the need for much of the data access "mechanical" code that you would normally write. Mapping POCO entity classes that do not depend on any EF type. Models can be generated from existing databases and then manually edited, or they can be created from scratch and then used to generate new databases. Integration with .NET Framework application models, including ASP.NET, and through data binding, with WPF and WinForms. Database connectivity based on ADO.NET and various providers available to connect to SQL Server, Oracle, MySQL, SQLite, PostgreSQL, DB2, etc.

    LINQ to DB

    LINQ to DB

    Linq to database provider

    LINQ to DB is the fastest LINQ database access library offering a simple, light, fast, and type-safe layer between your POCO objects and your database. Architecturally it is one step above micro-ORMs like Dapper, Massive, or PetaPoco, in that you work with LINQ expressions, not with magic strings, while maintaining a thin abstraction layer between your code and the database. Your queries are checked by the C# compiler and allow for easy refactoring. However, it's not as heavy as LINQ to SQL or Entity Framework. There is no change-tracking, so you have to manage that yourself, but on the positive side you get more control and faster access to your data. In other words LINQ to DB is type-safe SQL. Alternatively, you can implement custom settings provider with ILinqToDBSettings interface. You can generate POCO classes from your database using T4 templates.

    EF Core

    EF Core

    Object-database mapper for .NET

    EF Core is a modern object-database mapper for .NET. It supports LINQ queries, change tracking, updates, and schema migrations. Entity Framework Core is a modern object-database mapper for .NET. It supports LINQ queries, change tracking, updates, and schema migrations. EF Core works with many databases, including SQL Database (on-premises and Azure), SQLite, MySQL, PostgreSQL, and Azure Cosmos DB. To install EF Core, you install the package for the EF Core database provider(s) you want to target. This tutorial uses SQLite because it runs on all platforms that .NET Core supports. This application intentionally keeps things simple for clarity. Connection strings should not be stored in the code for production applications. You may also want to split each C# class into its own file. Query and manage relational data in a .NET Core app with an Object-Relational Mapper (O/RM).
