Solution Explorer does not load on a vanilla Console App #16

Closed deadlydog closed 9 months ago

deadlydog commented 9 months ago

Describe the bug

When creating a new Console Application, when Visual Studio loads, the Solution Explorer does not load as expected. Instead it shows the following error message.

Failed to create view with exception:
System.NullReferenceException: Object reference not set to an instance of an object.
   at WorkspaceFiles.WorkspaceRootNode.BuildAllDirectories() in D:\a\WorkspaceFiles\WorkspaceFiles\src\MEF\WorkspaceRootNode.cs:line 86
   at WorkspaceFiles.WorkspaceRootNode.get_Items() in D:\a\WorkspaceFiles\WorkspaceFiles\src\MEF\WorkspaceRootNode.cs:line 75
   at Microsoft.VisualStudio.PlatformUI.AggregateAttachedCollectionSource.InitializeItemCollection()
   at Microsoft.VisualStudio.PlatformUI.AggregateAttachedCollectionSource.get_InnerItems()
   at Microsoft.VisualStudio.PlatformUI.SolutionNavigatorPane.HookShowSolutionNodeEvents(IVsHierarchyItem solution)
   at Microsoft.VisualStudio.PlatformUI.SolutionNavigatorPane.RefillNavigator(Boolean skipRestorePhase, Boolean isFirstLoad)

To Reproduce Steps to reproduce the behavior:

  1. Open Visual Studio 2022
  2. At the welcome splash screen, choose Create a new project.
  3. Select Console App (C#) and hit the Next button.
  4. Leave the default project name ConsoleApp1 and use whatever Location you like. e.g. I used C:\Users\Dan.Schroeder\Desktop\Temp. Hit the Next button.
  5. Use the `.NET 8.0 (Long Term Support) Framework.
  6. Hit the Create button.
  7. When Visual Studio loads with the new project, the Solution Explorer shows an error message instead of the solution tree.

If I close Visual Studio and re-open the solution, the problem persists. If I disable the File Explorer extension and restart Visual Studio, then the Solution Explorer loads as expected.

Expected behavior

The solution explorer should load as expected.
