OTforDept is the application's name.The server has vs 2008 and vs 2010 with .net framework 2.0 and 3.5. However, my application was developed on client with vs2010 and .net framework 4.0. Will installing .net 4.0 on the server rectify this issue?

Could not load file or assembly - deploying asp.net application

The successor to Active Server Pages, ASP.NET websites utilize the .NET framework to produce dynamic, data and content-driven web applications and services. ASP.NET code can be written using any .NET supported language. As of 2009, ASP.NET can also apply the Model-View-Controller (MVC) pattern to web applications
