specflow error in migration to .net6

  Hi Team,

I have migrated the specflow project from .netstandard 2.0 to .net 6. It works fine with .netstandard 2.0 but after i did the migration, when i run the unit test i got the below error.

  Message: 
No matching step definition found for one or more steps.
using System;
using TechTalk.SpecFlow;

namespace MyNamespace
{
    [Binding]
    public class StepDefinitions
    {
        private readonly ScenarioContext _scenarioContext;

        public StepDefinitions(ScenarioContext scenarioContext)
        {
            _scenarioContext = scenarioContext;
        }
        [Given(@"the Logic App ""(.*)"" on ResourceGroup ""(.*)""")]
        public void GivenTheLogicAppOnResourceGroup(string p0, string p1)
        {
            _scenarioContext.Pending();
        }

The error appears for each statement from the feature file. Not sure what is the cause. Please can someone help really appreciate.

Thanks in advance
