When developing Sharepoint 2010 Web Parts with Visual Studio, I understand you need to have SharePoint installed on the same development box. (This all works fine) Now when we need to deploy the solution/ Web part to our Production SharePoint server do we simply export the web part and upload through Sharepoint? or do we need Visual Studio on the Production box also?
And should we deploy using the sandbox option?
We managed to deploy web part using the sandbox option but when our developer made changes to the solution and redeployed we still only see the old web part. (We deactivated the old web part and even deleted it ) It's as if it is being cached. Any ideas?
