New Post: Error in WixSharp_Load_Action

Thanks for reply, but question, is any way to create msi whom don't need framework 3.5 for work (but can work with 4.5 or higher)
Core of Win# falls with error if 3.5 isn't in system

"Info: Calling custom action WixSharp!WixSharp.ManagedProjectActions.WixSharp_Load_Action
Info: WixSharp aborted the session because of the error:
System.NullReferenceException: object reference not set to an instance of an object"

But installing 3.5 on Win 10.... i can, but it's not nicely.
Can you help with it ?
