Tsunami hangs trying to run OxyPlot in a WinForm

[jackfoxy]

Running the following works fine submitting to fsi from VS2012, but trying to run in Tsunami the WinForm window opens, but then hangs

I "C:\Packages"

r "OxyPlot.Core.2013.1.74.1/lib/portable-net4+sl4+wp71+win8/OxyPlot.dll"

r "OxyPlot.WindowsForms.2013.1.74.1/lib/NET45/OxyPlot.WindowsForms.dll"

r @"C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework.NETFramework\v4.5\System.Windows.Forms.dll"

r @"C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework.NETFramework\v4.5\System.Core.dll"

r @"C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework.NETFramework\v4.5\System.Drawing.dll"

open System.Windows.Forms open OxyPlot open OxyPlot.Series

type Form1() as this = inherit Form()

let plot1 = new WindowsForms.Plot() do this.Controls.Add plot1 do plot1.Dock <- System.Windows.Forms.DockStyle.Fill

let pm = new PlotModel("Trigonometric functions", "Example using the FunctionSeries")

let fs = new FunctionSeries(sin, 0.0, 6.28, 0.1, "sin(x)")

do pm.Series.Add(fs); do plot1.Model <- pm

let f = new Form1() f.Show()

G’day Jack, by default the Tsunami FSI runs in process which enables a number of cool features but causes some issues like this. It’s likely that running certain parts on the UI thread using (Tsunami.Utilities.Dispatcher.invoke) will fix it. Alternatively you could spin up a new FSI instance in the Consoles group in the ribbon. Then select the new FSI instance from the dropdown to send all Alt-Enter text to the new process.

Dispatcher.invoke(fun _ -> f.Show())

Runs just fine.
