A family of Microsoft suites of integrated development tools for building applications for Windows, the web, mobile devices and many other platforms. Miscellaneous topics that do not fit into specific categories.
The error shown is a generic IntelliSense/load failure and, from the provided information, maps to missing or misconfigured Visual Studio components required by the project type.
To resolve it, ensure that all required workloads and components for the project type are installed, then reload the project:
- In Visual Studio 2022, select Tools > Get Tools and Features to open Visual Studio Installer.
- For Windows desktop projects (WinForms/WPF/WinUI, VB/C#), make sure the .NET desktop development workload is installed. For C++ desktop projects, ensure Desktop development with C++ is installed.
- If the project uses Windows Installer or ClickOnce deployment, also install the Visual Studio Installer Projects extension if applicable.
- Close Visual Studio after installation completes, then reopen it and reload or recreate the project.
If the project was created with a third‑party installer tool (such as InstallShield), repair that tool’s installation and then reopen the solution.
