Upgrading WebBrowser class into WebView class in winforms application

Question

In my winforms application, I used WebBrowser class which is using IE browser. I want to update it into WebView class so that I can use Edge browser. That's why I installed packages Microsoft.Toolkit.Forms.UI.Controls.WebView. Then I changed some existing code which is compatible with WebView. But when I ran the project, I found the below errors after installing that package.

The item "C:\Projects\windows-v2\packages\System.Runtime.WindowsRuntime.4.6.0\build\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.

Looks like you are looking into the wrong package. You need to install `Microsoft.Toolkit.Forms.UI.Controls.WebView`. — Reza Aghaei, Dec 10 '19 at 16:05
Sorry, it's my mistake. Actually I installed that package. I updated the text. — Md Isfar Uddin, Dec 11 '19 at 08:36
Do you have any idea about the mentioned error? I followed the same steps as you described in your answers. @RezaAghaei — Md Isfar Uddin, Dec 11 '19 at 08:38
I tried in a clean solution/project without any problem. So I suggest you create a clean solution/project and give it a try. — Reza Aghaei, Dec 11 '19 at 08:49
Yeah clean solution is working. But problem with existing solution. — Md Isfar Uddin, Dec 11 '19 at 12:03
It's pretty hard to guess what's going on in your local project. In such cases, I may clean up the packages folder and after making sure about using correct package version, restore packages. — Reza Aghaei, Dec 12 '19 at 17:52

I found the solution and I am answering my own question. If anyone will face same problem then it will help.

The problem is not in the code. It is a problem in visual studio upgrading problem. Previously the project was in VS 2015 version but when I upgraded the webView, I used VS 2017 version. This is the reason to show the error "ReferencePath" does not define a value for metadata "CopyLocal".

To solve this problem go to the following directory:

C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional\MSBuild\15.0\Bin and open Microsoft.Common.CurrentVersion.targets file. Then at Line 3961 change this ...Include="@(ReferencePath)" into ...Include="@(ReferencePath.CopyLocal)"

For 2019 VS is Line 3948, or better, you need to find tag <_CopyLocalFalseRefPaths> – IR_IR May 28 '20 at 16:23
This solution worked for me, but I also had to Migrate packages.config to PackageReference – Matias Masso Aug 31 '20 at 11:27

To use a WebViewCompatible control in a Windows Forms application:

Install package Microsoft.Toolkit.Forms.UI.Controls.WebView
Right click on an empty area in Toolbox → select Choose Items → From the Choose Toolbox Items → choose .NET Framework Component tab → Click on Browse → Browse the package folder and choose Microsoft.Toolkit.Forms.UI.Controls.WebView dll → Click Open → Click OK
Drop an instance of WebViewCompatible control on the form.
In the Load event or in constructor after InitializeComponent add code to navigate to the address you want:
```
webViewCompatible1.Navigate("https://www.google.com");
```
