问题
I have a solution with a single project file. I am deploying as a ClickOnce application. It all runs fine and well on my computer but when I try to run it on someone else's I get this error
System.IO.FileNotFoundException: Could not load file or assembly 'System.Windows.Forms.DataVisualization, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified.
File name: 'System.Windows.Forms.DataVisualization, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'
System.Windows.Forms.DataVisualization is in facet loaded as a reference in my project and I believe there to be appropriate using statements where ever it is being used.
When I go to my project Properties>Publish>Application Files... System.Windows.Forms.DataVisualization has an exclamation point next to it that tooltip text of "This item is no longer referenced by the project. If it is no longer needed, it can be removed by right clicking on the item." the Publish status is "Include" and the Hash is "Include." the publish status is not, however, "Include (auto)"; Exclude has the auto text next to it. But whether I include or exclude I get the same error when running on someone else's machine.
What do you think I should do to get this file to be properly referenced?
Thanks
Update:
I've tried setting Local Copy = true, build rebuild to no avail.
I'm going through all the other suggestions now. (It's a long walk between me and the computer that doesn't work!)
回答1:
Sounds like you need to include the linked download in the in your redist - even if you've got the assembly you'll probably be missing dependencies:

回答2:
reinstall MSChart.exe
this helped me!

I know it has been a while since this problem was posted, but I just had the same problem and managed to solved it.
In order to run the application on other machines, I installed Microsoft Chart Controls on the other machines - just by downloading and running the MSChart.exe at http://www.microsoft.com/download/en/details.aspx?id=14422.

This specific issue was discussed on MSDN:

That post points to a suggested solution:

Generally, Fuslogvw (fusion log viewer) is your friend understanding why references cannot be loaded by .NET.
When logging is active, the strategy used to try and resolve dependencies is logged and fuslogvw lets you see the strategy.
Run in the computer where the DLL is found and the computer where it is not found and compare the log results.

Maybe the dll is in your GAC so .net find it. But you don't deploy it with your application and it failed on other computers. What you can do is find the dll add it as a reference to your project (because you lose it) and ensure that copy local is set to true.

Just Change version the in web.comfig file
EX:- namespace="System.Web.UI.DataVisualization.Charting" assembly="System.Web.DataVisualization, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"
