I want to go from View

<table style="width:100%">
<tr>
    <th>Serviço</th>
    <th>Data</th>
    <th>Feito</th>
</tr>
@{
    foreach (var item in ViewBag.servico)
    {
<tr>
    <td>@item.Servico</td>
    <td>@item.Data</td>
    <td>@item.Feito</td>
    <td>Editar</td>
    <td>
        <form action="/Tarefas/Remover" method="post">
            @{
                var tarefa = item;
             }
            <input type="submit" value="Excluir" />
        </form>
    </td>
</tr>
    }
}

For the controller:

[HttpPost]
public IActionResult Remover(Tarefa tarefa)
{
    using (var item = new AgendaDBContext())
    {
        item.Servicos.Remove(tarefa);
        item.SaveChanges();

    }
    return View("Lista");
}

Already tried passing only the controller in Action? <form action="/Tarefas" method="post">

<form action="/Tasks/Remove" method="post"> I’m going through post, I just don’t know how to pass the object

Your fields need to be inside the form and attribute name fields need to be the same properties names that refer to their model Tarefa.

Include the structure of the entity Tarefa in your question

RESOLVED * I’m just not sure if this would be a bad practice, I’m sending the id to controller by creating a new task instance and associating it with an id and sent to Entity to delete.

Creating a new instance is a bad practice ?

<table style="width:100%">
<tr>
    <th>Serviço</th>
    <th>Data</th>
    <th>Feito</th>
</tr>
@{
    foreach (var item in ViewBag.servico)
    {
<tr>
    <td>@item.Servico</td>
    <td>@item.Data</td>
    <td>@item.Feito</td>
    <td>Editar</td>
    <td>
        <form action="/Tarefas/Remover" method="post">
                <input type="hidden" name="id" value="@item.Id" />
            <input type="submit" value="Excluir" />
        </form>
    </td>
</tr>
            }
}

Controller:

[HttpPost]
    public IActionResult Remover(int id)
    {            
        using (var item = new AgendaDBContext())
        {
            Tarefa tarefa = new Tarefa();
            tarefa.Id = id;
            item.Servicos.Remove(tarefa);
            item.SaveChanges();

        }
        return RedirectToAction("Lista", "Tarefas");
    }
