I'm running into a deployment problem in my sharepoint 2010 environment. I built a small 'Hello World' type web part in visual studio 2010 and then deployed to my development environment via visual studio. Everything works fine so I moved the .wsp file to my production server and attempted to deploy via powershell using the add-spsolution and install-spsolution commands.
Everything appears to work fine, there were no errors, and I've checked in Central admin and the solutions are listed as deployed under Central Administration -> Solution management. Running get-spsolution tells me the same thing, and I've confirmed that the safe control entry was added to the web.config file for the site and it appears (to me anyway) to be listed correctly in the assembly folder for windows.
But for whatever reason, I cannot see it when I try to add a webpart to a page or when I view the web part gallery list under Site Settings?
I've tried adding the .webpart file directly from my project to the gallery but that then creates the following error message when I try to add it to the page afterwards:
Thank you in advance for any help!
