This is required for cases where It is required to build complex sql from the user input from UI. Currently in the project I am working is using String Manipulation which looks ugly and is difficult to maintain.

Try DbExtensions, available as NuGet package.

I was able to find a very good library for creating dynamic sql in .Net.

Not that I am aware of (although that doesn't mean there definitely isn't).
What about Entity Framework? It allows the query to be built up and translates that to SQL against entities:
customers.OrderBy(c => c.Name).Skip(10).Take(20)
Generates:
SELECT value c
FROM NW.Customers AS c
ORDER BY c.Name skip 10 limit 20;

Anything wrong with Linq-to-Sql?
var dc = new YourDataContext();
var query = dc.TableName.Where(x=>x.MatchesYourPredicate);
Console.WriteLine(dc.GetCommand(query).CommandText);

I always build my own... it's quick and easy and you don't have to rely on 3rd-party libraries. Plus it helps you become that little bit more intimate with SQL.
