Error in compile xibo dotnetclient develop source in visual studio

Hello evry
I get this error when i open xibo-dotnetclient-develop source in visual studio 2015:

Could not load file or assembly ‘file:///C:\mypath\xibo-dotnetclient-develop\wmpdll\AxInterop.WMPLib.dll’ or one of its dependencies. Operation is not supported. (Exception from HRESULT: 0x80131515) XiboClient C:\mypath\xibo-dotnetclient-develop\SGEN

If you right click on those files and select properties you will probably be offered to “Unblock” the files. Windows has blocked them because they weren’t “installed” and didn’t originate on your PC.
