[Problem/Bug]: net core warnings for missing DLLs in a .NET Framework 4.8 solution

[rozeboosje]

What happened?

I have a .NET Framework 4.8 Solution that uses WebView2. We updated the nuget package to 1.0.2739.15 and now when I build the software I am getting the following warnings in the Error List

Severity Code Description Project File Line Suppression State Details
Warning The referenced component '.nuget\packages\microsoft.web.webview2\1.0.2739.15\build..\lib_manual\netcoreapp3.0\Microsoft.Web.WebView2.Wpf.dll' could not be found. KHFramework
Warning The referenced component '.nuget\packages\microsoft.web.webview2\1.0.2739.15\build..\lib_manual\netcoreapp3.0\Microsoft.Web.WebView2.WinForms.dll' could not be found. KHFramework
Warning The referenced component '.nuget\packages\microsoft.web.webview2\1.0.2739.15\build..\lib_manual\netcoreapp3.0\Microsoft.Web.WebView2.Core.dll' could not be found. KHFramework
Warning The referenced component '.nuget\packages\microsoft.web.webview2\1.0.2739.15\build..\lib_manual\net6.0-windows10.0.17763.0\Microsoft.Web.WebView2.Core.Projection.dll' could not be found. KHFramework

Since our Solution targets .NET Framework 4.8 I'm not sure why these warnings should be relevant and they should therefore not appear. The software appears to work fine after building but we don't want to simply ignore warnings.

Importance

Moderate. My app's user experience is affected, but still usable.

Runtime Channel

Stable release (WebView2 Runtime)

Runtime Version

128.0.2739.42

SDK Version

1.0.2739.15

Framework

WPF

Operating System

Windows 11

OS Version

No response

Repro steps

As far as I can tell this just requires a .NET Framework 4.8 Solution that uses WebView2. When you build it these warnings appear. The resulting software seems to work fine so it doesn't seem to affect end users but unnecessary warnings clutter the "error list" and this might lead to us missing something that's important so if something can be done to remove these warnings I would appreciate it.

Repros in Edge Browser

No, issue does not reproduce in the corresponding Edge version

Regression

Don't know

Last working version (if regression)

No response

Hi @rozeboosje , thank you for reporting the issue. It seems related to #4743 which has been fixed and I have provided the internally built SDKs to the chat. Can you please try checking whether you can repro the problem with 1.0.2805 and/or 1.0.2805-prerelease?

Hello @oggy22 sorry for the delay

At the moment in the nuget package manager the latest prerelease available to me is 1.0.2783-prerelease so it looks like I cannot install 1.0.2805 just yet?

It seems like you need to make sure you set the sources to local folder where you downloaded the nuget files. You navigate to your project in the Solution Explorer, right click on the solution -> Manage Nuget Packages... On the top-right side change the Package Source to point to the local folder where you downloaded the file (and renamed it).
