New Post: Does not contain a definition for 'EagerEvaluate'

 I'm trying some sample codes in R.NET and planning to use it for an existing script. But I'm stuck with the following error

Error 'RDotNet.REngine' does not contain a definition for 'EagerEvaluate' and no extension method 'EagerEvaluate' accepting a first argument of type 'RDotNet.REngine' could be found (are you missing a using directive or an assembly reference?)

 private void button1_Click(object sender, EventArgs e)
        {
            string rhome = System.Environment.GetEnvironmentVariable("R_HOME");
            if (string.IsNullOrEmpty(rhome))
                rhome = @"C:\Program Files\R\R-3.0.1";
            System.Environment.SetEnvironmentVariable("R_HOME", rhome);
            System.Environment.SetEnvironmentVariable("PATH",System.Environment.GetEnvironmentVariable("PATH"));

           REngine.SetDllDirectory(@"C:\Program Files\R\R-3.0.1\bin\i386");

           using (REngine engine = REngine.CreateInstance("RDotNet"))
           {

            try
            {
                // import csv file
                engine.EagerEvaluate("dataset<-read.table(file.choose(), header=TRUE, sep = ',')");
 
                // retrieve the data frame
                DataFrame dataset = engine.EagerEvaluate("dataset").AsDataFrame();
 
                for (int i = 0; i < dataset.ColumnCount; ++i)
                {
                    dataGridView1.ColumnCount++;
                    dataGridView1.Columns[i].Name = dataset.ColumnNames[i];
                }
