we did dependency injection using:

replace square brackets with angled brackets, youtube doesn't allow angled brackets:

builder.Services.AddDbContext[AppDbContext](
optionsBuilder =]
optionsBuilder.UseMySql(connectionString,serverVersion));



example code for AppDbContext injection if we have configured AddDbContext..


private AppDbContext _DbContext;

private IComponentCollection _componentCollection;

public ComponentRepoMariaDb(AppDbContext DbContext,
IComponentCollection componentCollection){

this._DbContext = DbContext;
this._componentCollection = componentCollection;

this._DbContext.createDatabase();

}
