Sailaja Hima Software Developer Booya Ventures

In the past I used an ActiveX lib which was so buggy to integrate it into my .NET app. After many trials and errors, I decided to buy a true component. This Ultimate SFTP to be more expensive than some other competitors. But I still gave it a try. The API is very easy to understand and well documented. Without hesitation, I decided to choose the Company license of this component over other competitors.

The Ultimate SAML is solid, very easy to use. I have used some other library and I can assure anyone buying that this is the best SAML library for .NET around. Their response time is impressive.
