'ScenarioInfo' does not exist in the namespace 'TechTalk.SpecFlow'

[dvkbabu]

Framework was designed with specflow. I have installed reqnroll and reqnroll compatibility extenstion as well. I have uninstalled specflow from the project. When I build the project in visual studio. I am facing below issues. Please suggest how to resolve these.

Test.feature
The type or namespace name 'ScenarioInfo' does not exist in the namespace 'TechTalk.SpecFlow' (are you missing an assembly reference?)

Test.feature.cs
The type or namespace name 'ITestRunner' does not exist in the namespace 'TechTalk.SpecFlow' (are you missing an assembly reference?)

The sample code in CS files are below

private static TechTalk.SpecFlow.ITestRunner testRunner;

testRunner = TechTalk.SpecFlow.TestRunnerManager.GetTestRunner(null, 0);

public virtual void ScenarioInitialize(TechTalk.SpecFlow.ScenarioInfo scenarioInfo)

TechTalk.SpecFlow.FeatureInfo featureInfo = new TechTalk.SpecFlow.FeatureInfo(new System.Globalization.CultureInfo("en-US"), "CreateMyAccount", @"This is where we will place the scenario's

TechTalk.SpecFlow.ScenarioInfo scenarioInfo = new TechTalk.SpecFlow.ScenarioInfo("Validate No button in the page"

If you have built a framework or any amount of code that was designed with SpecFlow and would like to start using it with Reqnroll, you should be able to replace in code all instances of "TechTalk.SpecFlow" with "Reqnroll" and get a compatible result. Any references to "TechTalk.SpecFlow" are unlikely to work, because that is a different product.
