Unit test adapter failed - Data driven test - Visual studio 2013 vs 2015

I am working on some data driven unit tests which runs fine on VS 2013 but fails on VS 2015. I am using CSV file as my data source. I am not sure whether I am missing any configuration settings. i just followed MSDN article and tried various troubleshooting steps provided by others. No Luck. Any suggestions.

Test settings
1) CSV file properties - Build action set to content. Copy to o/p directory - copy always
2) Added the CSV file to deployment section of test settings

Code:

[TestMethod]
        [DataSource("Microsoft.VisualStudio.TestTools.DataSource.CSV", "TaxYears.csv", "TaxYears#csv", DataAccessMethod.Sequential)]
        public void TestMethod_1()
        {

Thanks in advance for your time and help
