WCF RIA service not found when migrating from win7 to win10

I have a silverlight app hosted on windows 7 and IIS, it works fine

I'm trying to move to a different box (windows 10) and its not working
I've run fiddler tool and can see the SVC binary requests are not found (404)
As this is a direct copy of the published code, I assume its setup related
If i run the project through visual studio it works fine, but in IIS does not

Here is an example of the url that isn't found on the new box:
http://localhost/MasterUI/ClientBin/MasterUI-Web-GuiViews.svc/binary/GetV_gui_TempAlarmGraph_by_Site?site=0001&ent=FFFFFFFF
The above gives a 404 in fiddler

The previous request to the XAP file works and does NOT 404
http://localhost/MasterUI/ClientBin/MasterUI.xap

I've tried to duplicate the IIS setup as much as possible, but for some reason it isn't working

My solution consists of 2 projects
MasterUI (silverlight stuff here)
MasterUI.Web (this is the non silverlight app - .aspx files)


The windows 10 box is a fresh install, so perhaps i'm missing some components, but as its working in visual studio on this windows 10 box, I assume it's IIS setup related?

Hi websss,

1. Delete .vs (hidden folder) from your project folder.
2. Check if IIS or IISExpress is properly installed or not.
