Can't use on Sharepoint Online, invalid markup.


Tried uploading to Sharepoint Online to use it, but it was a nogo. Here's the error:

Sorry, something went wrong

This solution contains invalid markup or elements that cannot be deployed as part of a sandboxed solution. Solution manifest for solution 'd49cf67c-9102-4ac5-ae6a-f9bf32e57a70' failed validation, file manifest.xml, line 6, character 4: The element 'Solution' in namespace 'http://schemas.microsoft.com/sharepoint/' has invalid child element 'TemplateFiles' in namespace 'http://schemas.microsoft.com/sharepoint/'. List of possible elements expected: 'FeatureManifests, ActivationDependencies' in namespace 'http://schemas.microsoft.com/sharepoint/'.

Looks like you are trying to upload a Full Trust solution to the Sandbox User Solutions in SharePoint Online which is possible due to security requirements to deploy custom application pages (requires full trust).

I have just uploaded a Sandboxed User Solution as an alternate release, which should be suitable for use in SharePoint Online. It is slightly slower than the FullTrust solution, so you will see a noticeable delay between page load and the Paging controls being replaced, but it should work for you.
