You have a public-facing SharePoint 2010 site. The site resides on two Web front-ends that are not load balanced. You are asked to design an update for a Web Part to the site. The update requires modifications to the code in the global assembly cache (GAC). You need to design the update with minimal impact to users who are accessing the site.
Which approach should you recommend?
A. Deploy the update directly to the GAC. Perform an IISReset on each Web front-end.
B. Deploy the update directly to the GAC. Recycle the application pool for the SharePoint site on each Web frontend.
C. Deploy the update within a custom Microsoft Windows Installer package that copies the code into the GAC and performs an IISReset on each Web front-end.
D. Deploy the update in a SharePoint solution file.
