I have a small issue or a big one ...
So I have a SharePoint 2007 where a solution build in visual studio 2008 is deployed. Recently i've started to develop in 2010, i converted the solution to the correct format for the visual stiod 2010. Everything was converted more or less ok, i checked the manifest files they were identical for both solution.
But when I try to upgrade the solution in 2007 with the new solution, i get the following error:
The solution file located at "package.wsp" does not appear to be a valid upgrade for solution "package.wsp".The two solutions must have the same resource types (global or Web-application scoped).
Any idea how to solve this? And what could cause this error?
All the features seems to be deployed withthe correct scope and the resource files also.
