Wrap a Hangfire job in a transaction

Question

I'm looking for a way to globally wrap db calls in a Hangfire background job in a transaction, similar to implementing the IAsyncActionFilter in AspNetCore.

I have tried implementing the IServerFilter but I don't seem to be getting the same instance of the DbContext when I run my query in the job, so the transaction is always null. (Rollback on error is purposely not yet implemented.)

public class DbContextTransactionFilter : IServerFilter
{
    private readonly MyContext _dbContext;

    public DbContextTransactionFilter(MyContext dbContext)
    {
        _dbContext = dbContext;
    }

    public void OnPerforming(PerformingContext filterContext)
    {
        Task.Run(async () => await _dbContext.BeginTransactionAsync());
    }

    public void OnPerformed(PerformedContext filterContext)
    {
        Task.Run(async () => await _dbContext.CommitTransactionAsync());
    }
}

What is the proposed way of doing that?

Edit 1:

This is how I implemented the IAsyncActionFilter and I'm looking to do something similar for Hangfire jobs.

public class DbContextTransactionFilter : IAsyncActionFilter
{
    private readonly MyContext _dbContext;

    public DbContextTransactionFilter(MyContext dbContext)
    {
        _dbContext = dbContext;
    }

    public async Task OnActionExecutionAsync(ActionExecutingContext context, ActionExecutionDelegate next)
    {
        try
        {
            await _dbContext.BeginTransactionAsync();

            var actionExecuted = await next();
            if (actionExecuted.Exception != null && !actionExecuted.ExceptionHandled)
            {
                _dbContext.RollbackTransaction();

            }
            else
            {
                await _dbContext.CommitTransactionAsync();
            }
        }
        catch (Exception)
        {
            _dbContext.RollbackTransaction();
            throw;
        }
    }
}

Edit 2: This is how I register the db context and the filter in the startup class:

services.AddDbContext<MyContext>(options =>
          options.UseSqlServer(Configuration.GetConnectionString("MyDatabase")));

services.AddScoped<DbContextTransactionFilter>();

services.AddHangfire((provider, configuration) => configuration
.UseFilter(provider.GetRequiredService<DbContextTransactionFilter>())
);

services.AddHangfireServer();
