f# - WPF window will not open after adding namespace -

so have simple f# wpf application. working fine without declaring namespace , using multiple modules.

now, still compiles, nothing. nil in debug show either.

this current code not work.

namespace flow module mainapp = open scheme open system.windows allow app1 = new application() [<stathread>] app1.run(new main.mainwindow()) |>ignore

before worked when this

module mainapp open scheme open system.windows allow app1 = new application() [<stathread>] app1.run(new main.mainwindow()) |>ignore

i can show definition of mainwindow, long, class inherits window. allow me know if help. or if there other info give help issue.

your original code relies on implicit entry point:

"when programme has no entrypoint attribute explicitly indicates entry point, top level bindings in lastly file compiled used entry point."

you can either define function in module , explicitly mark entry point:

namespace flow module mainapp = open scheme open system.windows allow app1 = new application() [<entrypoint>] [<stathread>] allow main args = app1.run(new window())

or can go on utilize implicit entry point including namespace in module name:

module flow.mainapp open scheme open system.windows allow app1 = new application() [<stathread>] app1.run(new window()) |>ignore
