I use VS2010, C# I want to read RSS content from other sites and display them in my site, currently this process is performed manually (site admin searches other sites and copy/pastes related content in news items!), but I want to do it automatically and I think the best solution is RSS, I've tried several sample codes but none of them worked, is there an easy way to implement RSS reader in ASP.NET? what are my options here?
