Could not load file or assembly 'System.Web.Security.SingleSignOn, Version=188.8.131.52, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified.
I am getting above error. I am trying to do ADFS2.0 application. Targeted frame work in 4.0. This sample application was developed in VS 2010 and deployed in windows 2008 R2 server on which .net framework is 4.0 and ADFS2.0 was installed.
In assemblies I tried for 'System.Web.Security.SingleSignOn' dll but could not find out.

Based on your error message, please refer to check for which framework version the application is built, check if you have the framework version.
If you have that framework then check in IIS if your application is pointing to correct framework.
The same time you can check the steps of intallation by the link below:
There is a document about ADFS, please refer to the link below:
Hope it's useful for you.
