Excerpt from wordpress link:
I recevied this error while compiling my first C# production application. I had to do the following in Visual Studio for the project:
- In Solution Explorer, expand the References node and click the assembly listed in the error. Ensure Copy Local in the Properties grid is set to ‘True’.
- In the properties of the project, Publish | Application Files Tab, ensure the Publish Status for the assembly listed in the error is set to ‘Include’
Problem
I published my .net application using ClickOnce, and all my users get the following error message on trying to open the program: "Unable to install or run the application. The application requires that assembly Telerik.Windows.Data Version 2012.1.215.40 be installed in the Global Assembly Cache (GAC) first". The version I actually use in my application is NEWER than the one mentioned in the error message. I also don't have this problem on my machine which I use to develop the application. I wonder why it is looking for the older version of the dll. I can't find where it is referenced by my application. Could you please help me on this?
