Could not load file or assembly 'System.Core, Version=3.5.0.0..'

After installing the application on the client, I try to open forms and they are working correctly. But for some other forms, an error message appears

Could not load file or assembly 'System.Core, Version = 3.5.0.0, Culture = neutral, PublicKeyToken = b77a5c561934e089' or one of its dependencies. " The system cannot find the file specified.

I click the details button to find the cause of the error, then check the appropriate source code line number as reported. Although the code works correctly on the development machine, I'm trying to find out why the problem appears on the line, I then realized that I am using LINQ and version of the .NET Framework on the client computer suspected as the cause of the problem.

I finally arrived at here and here. After upgrading to. NET Framework 3.5, the application run correctly.

Just picture it, .NET Framework 3.5 features include the following:

  • Deep integration of Language Integrated Query (LINQ) and data awareness. This new feature will let us write code written in LINQ-enabled languages to filter, enumerate, and create projections of several types of SQL data, collections, XML, and DataSets by using the same syntax.
  • ASP.NET AJAX lets you create more efficient, more interactive, and highly-personalized Web experiences that work across all the most popular browsers.
  • New Web protocol support for building WCF services including AJAX, JSON, REST, POX, RSS, ATOM, and several new WS-* standards.
  • Full tooling support in Visual Studio 2008 for feature sets in Windows Workflow Foundation (WF), Windows Communication Foundation (WCF), Windows Presentation Foundation (WPF) and Windows CardSpace, including the new workflow-enabled services technology.
  • New classes in .NET Framework 3.5 base class library (BCL) that address many common customer requests.
