What database management systems have you used in your projects?

In C# projects, the following DBMSs are often used:

• Microsoft SQL Server — the standard choice for .NET applications, well integrated with Entity Framework.
• PostgreSQL — popular due to its openness and advanced features.
• MySQL — frequently used in web projects.
• SQLite — used for lightweight applications or testing.

Example of connecting to MS SQL Server using Entity Framework Core:

var options = new DbContextOptionsBuilder<MyDbContext>()
    .UseSqlServer("Server=.;Database=MyDb;Trusted_Connection=True;")
    .Options;

using var context = new MyDbContext(options);
// work with the database
