: yes — but the phrase "create an online database using C# with a specific plug-in" needs a bit of clarification. C# is the language you use to build the app or API that talks to a database; the database itself is a DBMS (SQL Server, MySQL, PostgreSQL, etc.) hosted on a server or in the cloud. A "plugin" in this context is usually a NuGet provider/driver (for SQL Server use Microsoft.Data.SqlClient) or an ORM package such as Entity Framework Core.

To connect the dots from the existing replies: is correct that you pick a DBMS and host it, and pointed to a common access pattern. A practical flow that works today is:

  • Choose and provision the database (local server, VM, or managed service like Azure SQL).
  • Build a C# Web API (ASP.NET Core) that exposes CRUD operations.
  • Use an access library: EF Core (code-first with migrations) or a lightweight option like Dapper if you prefer raw SQL.
    A minimal EF Core model looks like this:
public class Item
{
    public int Id { get; set; }
    public string Name { get; set; }
}

public class AppDbContext : DbContext
{
    public DbSet<Item> Items { get; set; }
}

Run migrations to create the schema:

dotnet ef migrations add InitialCreate
dotnet ef database update

Troubleshooting tips: verify the correct connection string, ensure the DB server allows remote TCP connections and the firewall/IP rules permit access, match the EF provider version to your .NET runtime, and never commit plaintext credentials—use configuration or a secrets store. For hosting, managed DBs (Azure SQL, AWS RDS) handle availability and security for you.

Official guidance: Entity Framework Core modeling (https://learn.microsoft.com/ef/core/modeling/) and an ASP.NET Core EF tutorial (https://learn.microsoft.com/aspnet/core/data/ef-mvc/intro).

What are you triing to accomplish? Normally, the database would be created first using any of several DBMSs, such as SQL SERVER.
