c# – Add Reqnroll to an existing Microsoft Tests project doesn’t execute the tests

I have an existing project built with MSTest version 3.6.4 and Microsoft.NET.Test.Sdk 17.12.0 with all my unit tests.

I added Reqnroll to the project, and I created a feature. After the first build, I was able to generate the code for the feature

[Binding]
public class UserStory1StepDefinitions
{
    [Given("that the new cedant takeout")]
    public void Step1()
    {
        Assert.IsTrue(true);
    }

    [When("the Program")]
    public void Step2()
    {
        Assert.IsTrue(true);
    }

    [Then("create data")]
    public void Step3()
    {
        Assert.IsTrue(true);
    }
}

When I run the tests, none of the tests above is present in the list of running or pending tests. I noticed there is no TestClass or TestMethod.

How can I set those tests to be executed with the others?
