I'm trying to use Microsoft.WebView2 from microsoft.web.webview2.0.9.579.nupkg (TEdgeBrowser example from Delphi 10.4 Version 27.0.38860.1461)

This version works with canary or beta versions of Edge only. With release of Edge I got an error message Could not find Edge installation. Do you have a version installed that's compatible with this WebView2 SDK version?

Documentation says about canary versions of Edge only.

Which version of Microsoft.WebView2 will work with Edge release ?

    Why don't you try version `1.0.664.37` - the latest official release - and see if that works? – Poul Bak Dec 11 '20 at 09:06
  • @PoulBak - microsoft.web.webview2.1.0.664.37.nupkg - Edge release 87.0.664.60 error message: Could not find Edge installation. Do you have a version installed that's compatible with this WebView2 SDK version? – Mark Lobanov Dec 14 '20 at 09:00

I am not available with the Delphi app but I try to make a test with the Windows Forms app. In which, I download the webView2 1.0.664.37 using Nuget package manager and I try to test it with the MS Edge Version 87.0.664.60 (stable version at present).

Based on my test result, it did not work with the MS Edge Version 87.0.664.60 (stable version at present).

So as per this test result, the webView2 1.0.664.37 may not work in your Delphi app with the current stable version of the Edge browser (Version 87.0.664.60). You can test it in your Delphi app to verify it.

I make further tests and found that if I install the webView2 Evergreen Standalone Installer then it is working on my side. You can notice that there is a minor difference in the version of the webView2 runtime and MS Edge stable browser.

enter image description here

So if you are available to use the webView2 runtime then you can make a test with it.

If you cannot use the webView2 runtime and webView2 1.0.664.37 also not working in your Delphi app then I suggest you keep using the MS Edge Canary or Dev version with the webView2.

  • Thanks for your test. I have to display some web pages inside my desktop app I chose edge because it is a standard component of the operating system as it is now - an exporter i must have an industrial solution deploying e webView2 Evergreen IMHO is not a good idea – Mark Lobanov Dec 14 '20 at 07:59
  • I tested with webView2 Evergreen Error message: Failed to initialise Edge browser control – Mark Lobanov Dec 14 '20 at 09:06
  • WebView2 for .Net requires either WebView2 Runtime or the Canary build of Edge, not release builds of Edge! – Poul Bak Dec 14 '20 at 13:38
  • @MarkLobanov, In that case, I suggest you keep using the MS Edge Canary version as mentioned in the official document. I suggest you refer to this [link](https://learn.microsoft.com/en-us/microsoft-edge/webview2/#feedback) and try to provide feedback regarding webView2 by clicking on the `This Product` button under feedback options. Thanks for your understanding. – Deepak-MSFT Dec 15 '20 at 09:07
