# Entity Framework - Dead Ball Zone
This is a practice project to learn Entity Framework.
Using the 1998 game [Dead Ball Zone](https://en.wikipedia.org/wiki/Dead_Ball_Zone) for inspiration.
## .NET commands:
### NuGet commands
Install [Entity Framework Core NuGet package](https://www.nuget.org/packages/microsoft.entityframeworkcore):
`dotnet add package Microsoft.EntityFrameworkCore --version 9.0.3`
### Creation commands
To list all available templates:
`dotnet new -l`
New class:
`dotnet new class -n MyClass`
adding to an existing solution:
`dotnet sln add Data/Data.csproj`
## Terms
A **database-context** is an abstraction of the database structure in code.
* It lists the models and their database table names.
* It instantiates a database connection during the runtime of the application.
* Allows configurations to be made in code.
