I have been trying to get this working for about a day now, i dont really expect anybody else to have tried (not many)
1. I first tried installing the vsi via doubleclicking it, and than selecting it as template when i did "file -> new -> website"
completed some progress bars, but errored without leaving a project. "Exception from HRESUKT: 0x80041FEB"
2. Next i went into the folder where the .vsi are extracted when doubleclicked, looked for the template, found a zip and extracted that into the "websites" folder
Only 4 errors! some stuff about output caching which appearantly is not implemented backwards compatible in asp.net 4.0
When i clicked browse site i got the installation wizard, tried to install it , all was succesful (see attached file) but than when i tried to go to my portal, i just got 2 blanket errors.
3. Next i tried extracting the DNN source + install into the websites folder, and opening the vs2008.sln file with vs2010. It offered to import and convert all subprojects.
The converting and importing went ok, but than i was left with 270 errors and countless wanings/messages.
4. ctrl-c ctrl-v the "website" folder from the install/source package to the websites folder renamed it , and did "file -> open -> website" on it
only 33 errors, most of them backwards compatibility issues again.
