Unable to build VSTO project with WebView 6.1.2 because of “ReferencePath” does not define a value for metadata “CopyLocal” error

Describe the bug

Not sure it is the right place to ask, but maybe you can guide where to look. I am trying to use WebView control in the VSTO project for Outlook but unable to build because of the error: Error The item "C:\Users\sergeybelikov.nuget\packages\system.runtime.windowsruntime\4.6.0\buildTransitive\net461....\ref\netstandard2.0\System.Runtime.WindowsRuntime.dll" in item list "ReferencePath" does not define a value for metadata "CopyLocal". In order to use this metadata, either qualify it by specifying %(ReferencePath.CopyLocal), or ensure that all items in this list define a value for this metadata. OutlookAddin

The same control is working in a standalone WPF. And with 5.1.1 version of WebView package VSTO add-in is also compiling. Unfortunately, 5.1.1 missing event WebResourceRequested which we need to intercept POST data webpage is sending. We use it to get SAML2 auth token to use in our add-in. Maybe there is another way to do that?

I know that there is WebView2 already, but it is not released to .NET yet. And also we don't want to bloat the installer with 200+ Mb of runtime.

NuGet Package(s): Microsoft.Toolkit.Wpf.UI.Controls.WebView

Package Version(s): 6.1.2

Project .NET Version:

• .NET Framework 4.7

Visual Studio

• 2019 (version: 16.7.7)
