Scintilla.Net 5.3.1.3 don't work when Devexpress libraries added to project

[odysseus1973]

Hi!

Github issue from original branch

jacobslusser/ScintillaNET#526

Step-by-step reproduction

• Create blank WinForms app (Net 7)
• Install Scintilla.Net 5.3.1.3 nuget package
• Put Scintilla.Net control on form from toolbox
• All works fine
• Add Devexpress libraries to project (via open DevExpress Project Settings and click Add Libraries)
• Try to open Form In Design mode
• Scintilla control disappear.
• Try to put Scintilla control on form again - we get the following error

Request failures: DesignerHosts/CreateComponent.
                       Microsoft.DotNet.DesignTools.Client.DesignToolsServerException: Method not found: 'Void System.Security.AccessControl.MutexAccessRule..ctor(System.Security.Principal.IdentityReference, System.Security.AccessControl.MutexRights, System.Security.AccessControl.AccessControlType)'.

                       For information on how to troubleshoot the designer refer to the guide at https://aka.ms/winforms/designer/troubleshooting.

• Remove Devexpress package from project - all works fine now

I understand that you do not use commercial libraries, but please see what you can do

Thanks!

Hi,
I can use the DevExpress evaluation to debug the issue - when I have the time. I'm not sure if the Mutex creation is even required in the constructor of the control. It seems to relate to file use synchronization among processes, StackOverflow when extracting the Scintilla native DLL if one doesn't exist already.

Thank you. If you have time, add support for net 6 and net 7, please

Hi. the control should now work with the DevExpress library in design mode. The package was already targeting .NET 6

If you have time, add support for net 6 and net 7, please

.NET 7 TFM was added.
