There was a small mistake. the name in usingtask element had an 's' in the end. I corrected it and this time it gives me below error.

C:\Users\I868962\Documents\repos\WebApp1\yui\compressor.xml(9,5): error MSB4062: The "CompressorTask" task could not be loaded from the assembly C:\Users\I868962\Documents\repos\WebApp1\yui..\bin\Yahoo.Yui.Compressor.MsBuild.dll. Confirm that the declaration is correct, that the assembly and all its dependencies are available,and that the task contains a public class that implements Microsoft.Build.Framework.ITask.

I even tried msbuild yui\compressor.xml and the result is the same as shown below:

This time put the compressor.xml in the root and removed the relative path (..) in the xml file. Still its the same result as shown in below screen
