[MonoDevelop] How to delete the SSL certificate from Mono stores?

[Hari]

I am trying to delete the previously added certificates from the Mono
(3.6.0) store "MY" by using the below command in Linux
*Add:*

* certmgr -add -c -m My mycert.cer*
*Delete:*

*certmgr -del -c -m My mycert.cer*

But the above command is not deleting the certificate.
Is there any way to cleanup the mono certificate store? I am wondering if I
can use any other tools.

Thank You
