Visual Studio 2022 view code button missing on solution explorer-CodePudding

I'm doing a WinForms app (which I haven't done in a long time) and noticed that in VS 2022, the "view code" button (looks like <>) which used to be on the toolbar on the "Solution Explorer" window is missing. I know I can right-click on a form and reach it through the context menu, or hit F7, but is there any way to add it back? I can't seem to find any option for it.

CodePudding user response：

We can see “View Code” button in a solution which contain a .NET Framework winform project.

If we create a solution which contain a .NET 6 winform project the “View Code” button will disappear. We should right-click and reach it through the context menu or hit F7.

This issue has been submitted and is waiting to be resolved.

You can download or clone the solution here:

Here is the step by step guide on creating this extension:

Add new project and choose 'VSIX Project' and leave the default name.
Please note: To have this project type, you need to install 'Visual Studio extension development' when installing/modifying VS installation.
Add new item and choose 'Command' which is under 'Extensibility' group.
Open 'VSIXProject1Package.cs' file and add the following line of code to the class:
```
public const string UIContextGuid = "8B40D5E2-5626-42AE-99EF-3DD1EFF46E7B";
```
It could be any GUID.
Open 'VSIXProject1Package.vsct' file and add the following as child of <Symbols> node:
```
<GuidSymbol name="UIContextGuid" value="{8B40D5E2-5626-42AE-99EF-3DD1EFF46E7B}" />
```
The GUID here should be same as the GUID in previous step.

Modify the attributes of the '' class to be like this:

[PackageRegistration(UseManagedResourcesOnly = true, AllowsBackgroundLoading = true)]
[Guid(VSIXProject1Package.PackageGuidString)]
[ProvideMenuResource("Menus.ctmenu", 1)]
[ProvideUIContextRule(VSIXProject1Package.UIContextGuid,
name: "Supported Files",
expression: "CSharp",
termNames: new[] { "CSharp" },
termValues: new[] { "HierSingleSelectionName:.cs$" })]
public sealed class VSIXProject1Package : AsyncPackage

Open 'Command1.cs' and modify the ServiceProvider property to this:

private IServiceProvider ServiceProvider
{
    get
    {
        return this.package;
    }
}

Replace the ExecuteCommand with this:

private void Execute(object sender, EventArgs e)
{
    ThreadHelper.ThrowIfNotOnUIThread();
    var dte =  ServiceProvider.GetService(typeof(DTE)) as DTE; 
    ProjectItem item = dte.SelectedItems.Item(1)?.ProjectItem;
    if (item != null)
    {
        VsShellUtilities.OpenDocumentWithSpecificEditor(package,
            item.FileNames[1],
            Microsoft.VisualStudio.VSConstants
                .VsEditorFactoryGuid.TextEditor_guid,
            Microsoft.VisualStudio.VSConstants.LOGVIEWID.Code_guid);
    }
}

Add the following method:

private void MyQueryStatus(object sender, EventArgs e)
{
    ThreadHelper.ThrowIfNotOnUIThread();
    var button = (MenuCommand)sender;
    button.Visible = false;
    var dte = ServiceProvider.GetService(typeof(DTE)) as DTE;
    ProjectItem item = dte.SelectedItems.Item(1)?.ProjectItem;
    if (item != null)
    {
        string fileExtension = 
            Path.GetExtension(item.Name).ToLowerInvariant();
        string[] supportedFiles = new[] { ".cs"};
        button.Visible = supportedFiles.Contains(fileExtension);
    }
}

Open the '' file and replace the content of the Groups node with the following:

<Group guid="guidVSIXProject1PackageCmdSet" 
id="SolutionToolbarGroup" priority="0xF000">
   <Parent guid="guidSHLMainMenu" id="IDM_VS_TOOL_PROJWIN"/>
</Group>

Replace the child of the GuidSymbol which has name = guidVSIXProject1PackageCmdSet with the following:

<IDSymbol name="Command1Id" value="0x0100" />
<IDSymbol name="SolutionToolbarGroup" value="0x0190"/>

Add the visibility constraint, right after the end of </Commands> tag:

<VisibilityConstraints>
   <VisibilityItem guid="guidVSIXProject1PackageCmdSet"
   id="Command1Id"
   context="UIContextGuid" />
</VisibilityConstraints>

Modify the generated button tag to:

<Button guid="guidVSIXProject1PackageCmdSet" id="Command1Id" priority="0x0100" type="Button">
   <Parent guid="guidVSIXProject1PackageCmdSet" id="SolutionToolbarGroup" />
   <Icon guid="guidImages" id="bmpPic1" />
   <CommandFlag>DefaultInvisible</CommandFlag>
   <CommandFlag>DynamicVisibility</CommandFlag>
   <Strings>
      <ButtonText>Invoke Command1</ButtonText>
   </Strings>
</Button>

Run the project and see the result.
