I need to have a web browser (and its contents) within the LabView environment. The existing IWebBrowser2 uses the Internet Explorer 11 compatibility which is getting old... As far as I know, the WebView2 control can be used only in Visual Studio or similar environment. Is it some way that I can use it inside Labview?

@GregFreeman wrote: Edit: I removed the CLFN calls which are being used to set the DLL paths. I then copied the WebView2 DLLs and the Releases directory into C:\Program Files (x86)\National Instruments\LabVIEW 2019. This works. That means the problem is being caused by the calls that are adding paths to the DLL search path. That call certainly could mess up things for good. You only pass in the 0x400 flag, effectively disabling the loading of application extensions from the current process directory as well as any DLLs located in system32. This disables many things in Windows and while many parts of Windows are loaded and initialized at process creation time, some parts are continually reevaluated at runtime and possibly loaded at a later time. If a Windows code section comes across such a passage, the lack of system32 and/or process directory resources to be found can be devastating. To enable them too you would have to OR all the values in that list or use the special flag 0x1000 which combines them. Another interesting flag not mentioned in the MSDN documentation might be, LOAD_LIBRARY_SEARCH_DLL_LOAD_DIR = 0x00000100; This supposedly will enable Windows to search for dependencies in the same directory as where the current DLL is located that it tries to load. This flag is really meant for use with LoadLibraryEx() so it may not work for SetDefaultDLLDirectory().

I just got this working. I followed what Microsoft says here and installed the runtime. I then downloaded the webview2 package from the nuget repository. Once that was done i change the nupkg extension to .zip and then unzipped it. I then added a .net control on the LV front panel. I linked it to the webview2 control, and shown below is the block diagram with some comments. edit: you can probably remove the while loop around the CoreWebView reference. That was added before I got the wait on the async call to work correctly and I didn't remove it. Hope this helps:

Has anyone successfully used SSO? The attached VI below does NOT work but I'm certain has some of the things needed. The comment/code snippet in the VI is from a stackoverflow post that I'm trying to follow.
