How to organize multiple executable F# files into one VS solution?

I'm learning F# recently and using it to solve problems like "Haskell 99 problems" as a practice. I'm coding with Visual Studio 2013 Community on Windows.

My problem is that I don't know how to organize all my sources codes in one solution/project.

In other languages like Ruby, I could organize my source codes like:

haskell99/
    problem1.rb
    problem2.rb
    ...
    problem99.rb

I could code and execute each source file independently in any IDE.

But if I organize my F# source codes in a similar way in Visual Studio:

Solution 'Haskell99'
    Project 'Haskell99'
        problem1.fs
        problem2.fs
        ...
        problem99.fs

I can not just switch to a source code and press Ctrl+F5 to execute it. If I do so, all the source codes contained in this Solution will be compiled to one single .exe file.

I also tried other ways like one project per problem:

    Solution 'Haskell99'
        Project 'Problem1'
            Program.fs
        Project 'Problem2'
            Program.fs
        ...
        Project 'Problem99'
            Program.fs

Or F# scripts in a solution:

    Solution 'Haskell99'
        Project 'Haskell99'
            problem1.fsx
            problem2.fsx
            ...
            problem99.fsx

They all not work.

Is there any best practice to achieve this:

Switch to a source file by double click it; 
Then press Ctrl + F5 to ONLY compile and execute this source file.

Thanks for your response in advance.

If you need to start a debugger, then your one-project-per-problem is the only option. It's one extra step, but if you follow http://blog.michaelckennedy.net/2007/07/30/visual-studio-tricks-series-1-set-as-startup-project/ to add a hotkey to set-as-startup-project, then your process is

  • double-click the source file
  • hit ctrl-shift-p to set that as startup project
  • hit F5 to compile and execute the project with debugger attached

Or if you don't need the file open in the editor, it's just

  • single-click the project
  • hit ctrl-shift-p to set that as startup project
  • hit F5 to compile and execute the project with debugger attached

Install F# power tools, and when you have an .fsx file open in your editor, there's an option to "Execute in Interactive". You can map this to any key combo you want.
