Sharepoint 2010 sandboxed solution

Question

Hi,

I am using SharePoint 2010 and creating a simple web part using Visual Studio 2010. When I create a SharePoint project in visual studio 2010, I specify "Deploy as a sandboxed solution" option. When I run the project, in a page in the sharepoint site when adding a web part i can see the web part. But when i try to add the web part to the page, i received this error "The sandboxed code execution request was refused because the Sandboxed Code Host Service was too busy to handle the request.".

I have searched on the google for the error message. The resolution to this error is to start the "Microsoft SharePoint Foundation User Code Service" service in the Central Administration. However when i look at the Services on Server using central administration site, I am missing this service. I don't see this service I was able to run the sandboxed solutions before but it is not working any more. I don't know how to fix this.

Thanks, Hitesh

Hi,

I have finally got it fixed. The way i fixed it is Central Administration > System Settings > Manager user solutions, under Load Balancing, I selected "All Sandboxed code runs on the same machine as a request" option and it is all working now.

For some reason I am still missing this service - "Microsoft SharePoint Foundation User Code Service". However I have always had "Microsoft SharePoint Foundation Sandboxed Code Service" service listed under Services on central administration site. And I am using SharePoint Server Standard Edition so it may be that for Standard edition I have this service instead.
