Trying to setup SQLite with EntityFramework (Discord Bot /w DSharpPlus)

I'm trying to setup SQLite for my discord bot, and to start the DB file, I tried using this command

PM> Add-Migration InitialCreate -Context LloydWarningSystem.Net.Entities.LloydContext

PM> Add-Migration InitialCreate -Context LloydWarningSystem.Net.Entities.LloydContext

LloydContext is my class that inherits DbContext. However, this command just builds my bot then runs it then gives an exception saying it cant find my service.

PM> Add-Migration InitialCreate -Context LloydWarningSystem.Net.Entities.LloydContext
Both Entity Framework Core and Entity Framework 6 are installed. The Entity Framework Core tools are running. Use 'EntityFramework6\Add-Migration' for Entity Framework 6.

This is how I start the service (According to what I found with the DSharpPlus documentation

var builder = DiscordClientBuilder.CreateDefault(token,
   TextCommandProcessor.RequiredIntents
   | SlashCommandProcessor.RequiredIntents
   | DiscordIntents.MessageContents
   | DiscordIntents.GuildMembers)
   .ConfigureServices((services) =>
   {
       services.AddDbContext<LloydContext>(options =>
       {
           options.UseSqlite(connectionString);
       });

       Services = services.BuildServiceProvider();
   });

var builder = DiscordClientBuilder.CreateDefault(token,
   TextCommandProcessor.RequiredIntents
   | SlashCommandProcessor.RequiredIntents
   | DiscordIntents.MessageContents
   | DiscordIntents.GuildMembers)
   .ConfigureServices((services) =>
   {
       services.AddDbContext<LloydContext>(options =>
       {
           options.UseSqlite(connectionString);
       });

       Services = services.BuildServiceProvider();
   });

I have never done anything like this, so I'm very lost. I tried following tutorials on the DSharpPlus documentation (Even their example bots), but it didn't help too much.

Both Entity Framework Core and Entity Framework 6 are installed

Start by deleting EF6

jcotton42•3mo ago

EF6 runs on modern .NET?

oke•3mo ago

i removed all packages related to EF6, and now it's just running my bot and doing nothing within the package manager console. It's been open for ~5 minutes.

@oke https://learn.microsoft.com/en-us/ef/core/cli/dbcontext-creation?tabs=dotnet-core-cli i think is what you're looking for

right as i said that, it threw an exception

i'd use the design-time factory option From application services is the most ideal option though.

jcotton42•3mo ago
