We were able to reproduce this here now as well, and we should be able to fix it up for the next beta. ]]> RE: Function refers to Bitmap not working https://www.displayfusion.com/Discussions/View/function-refers-to-bitmap-not-working/?ID=b07d1c05-aa84-408e-89a2-2d4fc5b33e04#13 Fri, 12 Jun 2020 05:22:17 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/function-refers-to-bitmap-not-working/?ID=b07d1c05-aa84-408e-89a2-2d4fc5b33e04#13 DisplayFusion After trying serveral things out, I finally tracked down the issue.

It seems that when getting asking for common assembiles, Windows prioritized the ones bundled with Powershell 7.0 (maybe versions 6.x as well) instead of the ones included by .Net framework itself. But by design they do not always behave in the same way https://github.com/dotnet/runtime/issues/29823, particularly with WinForms. There are also several open issues related to the TypeHandler in net core 3.x which may be related.

Maybe a possible fix is fiddling around with the TargetFramework attribute and/or the assembly conversions to force referencing the correct assemblies.

However, the quickest way to solve the issue is to simply uninstall Powershell 7.0.x (6.x), this allows both scripts to compile.

The following issues were also resolved:
- Slow Settings UI
- Visual Basic scripting being completely broken

As a sidenote, I tried the latest 7.0.2 release but the issue persisted. However, after upgrading to 7.1 preview, which is based on .Net 5 (both include fixes regarding references and the TypeHandler), everything kept working ok. ]]> RE: Function refers to Bitmap not working https://www.displayfusion.com/Discussions/View/function-refers-to-bitmap-not-working/?ID=b07d1c05-aa84-408e-89a2-2d4fc5b33e04#12 Thu, 11 Jun 2020 23:34:44 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/function-refers-to-bitmap-not-working/?ID=b07d1c05-aa84-408e-89a2-2d4fc5b33e04#12 DisplayFusion My function is attached.

I downloaded the Gaussian Lock function and hit Verify Code. This was the result:

https://www.displayfusion.com/ScriptedFunctions/View/?ID=dd88a3f2-f17d-4cff-9db0-a03a8f9a2064

However, in this case, the error is:

(Note: My version is two functions, one calls the other and then locks the screen, so I can update the bitmap on a idle time schedule just before the computer locks due to idle time.)

It uses System.Drawing.Bitmap and has references to System.Drawing.dll and using System.Drawing and using System.Drawing.Imaging.

DF says it is forwarding Bitmap to System.Drawing.Common, which is a .Net Core extension package (I have .Net Core 3.1 with add-ons installed).

Has something changed in recent versions causing DF to try to use .Net Core packages?
