In this hint, I will briefly explain
What’s the difference between deploying as a Sandboxed solution and as a Farm solution?
Deploying as Farm Solutions In SharePoint
Farm solutions, which are hosted in the IIS worker process (W3WP.exe), Run the code that can affect the whole farm.
- When you debug a SharePoint project whose Sandboxed Solution property is set to “farm solution,” the system’s IIS application pool recycles before SharePoint retracts or deploys the feature so as to release any files locked by the IIS worker process. Only the IIS application pool serving the SharePoint project’s site URL is recycled.
Deploying as Sandboxed Solutions In SharePoint
Sandboxed solutions, which are hosted in the SharePoint user code solution worker process (SPUCWorkerProcess.exe), run code that can only affect the site collection of the solution.
- Because sandboxed solutions do not run in the IIS worker process, neither the IIS application pool nor the IIS server must restart. Visual Studio attaches the debugger to the SPUCWorkerProcess process that the SPUserCodeV4 service in SharePoint automatically triggers and controls. It is not necessary for the SPUCWorkerProcess process to recycle to load the latest version of the solution.
