can I build an x64-only modern app?


  • Both projects in my Solution are set to Target x64. When I build, I get

          Platform target 'x64' is not supported by one or more of the project's targets

    (hey guys, search and replace "one or more" in every error message you ever generate and replace it by code to deliver at least one specific name).

    Why can't I build for x64?  I'm barely started with the app, all I have is a few screen buttons and the barest beginning of logic to find and read one input file.  My data is going to span gigabytes, so I need x64.  Can I not do that in a modern App?

    If I can do it, what might be the target which is blocking?

  • Hi,

    What are the types of both the Projects? Is your development machine x64 system or x86? Or there could be some references in your projects that are not x64 compatible.
