First you need to add this in to your project folder.

After that you need to add it as an project.

Finally you need to add it as a Project Reference to your main project.

You can go get it by downloading wamp server. Link to guide: https://www.youtube.com/watch?v=C-50GV2uUu0

You need to add the Services you create and the RContext in your Startup.cs or your Program.cs if it is a discord bot, they need to be set as a singleton like this:

public void ConfigureServices(IServiceCollection services) {
	services.AddSingleton<RContext>();
	services.AddSingleton<MemberConnectionService>();

private ServiceProvider ConfigureServices() {
	ServiceCollection serviceCollection = new();
			
	serviceCollection
		.AddSingleton<RContext>()
		.AddSingleton<MemberConnectionService>(); // For Services.
}

You need to set the server connection under the debug tab under properties when you right click on your project.

If you look in the DBContext under the Data folder you will find some examples that I have taken from my bot.

Under the folder called Services you will find a few examples look at the MemberConnectionService.cs there is some examples on how to make one.

You can also copy the EmptyTamplateService.cs and use it.

The RContext.cs is located under the Data folder.

The RContext.cs is used to contact the database, using predefined functions that is described in the Repository.cs.

You need to Dependency Inject the RContext by doing this in the places where you want to contact your database here is how:

private readonly RContext _rContext;

//In order to make a ctor just write in ctor and hit tap twice.
//Ctor stands for constructor.
public CTOR(RContext rContext) {
	_rContext = rContext;
}

If you have made services then you can Dependency Inject them like this.

private readonly MemberConnectionService _memberConnectionService;

public CTOR(MemberConnectionService memberConnectionService) {
	_memberConnectionService = memberConnectionService;
}

You can Dependency Inject both of them or more like this.

private readonly MemberConnectionService _memberConnectionService;
private readonly RContext _rContext;

public CTOR(MemberConnectionService memberConnectionService, RContext rContext) {
	_memberConnectionService = memberConnectionService;
	_rContext = rContext;
}
