This collection already contains an address with scheme http. There can be at most one address per scheme in this collection. Parameter name: item

Problem : This is the problem occures when the bindings are many for your application and the web.config was unable to find the exact binding.

Solution: Here is the Web Config Lines without the escape sequences.







replace http://www.MyDomainName.com with your website name...if it is localhost give the exact binding.

It will work definately.
