Visual Studio 2022 - Solution Explorer not populating - Failed to create view with exception: System.Runtime.InteropServices.COMException (0x8000FFFF)
I tried to open an existing older .NET 4.8 REST API solution in Visual Studio 2022 version 17.4.4. I got this interesting error where the Solution Explorer pane did not load, and instead was populated with the following exception message:
"Failed to create view with exception: System.Runtime.InteropServices.COMException (0x8000FFFF): The hierarchy is not in a valid state. Make sure that the product is installed properly."
This project has MVC, Razor and EntityFramework. It's an older project, not built by me, so I don't have a whole lot of other info to share on it. This is the first time I have gotten this error.
I was expecting to see my solution load into Solution Explorer per the norm. I didn't try anything to resolve it outside of what I have shared below as an Answer.
Hi I am answering my own question here. The solution was to install the latest version of Visual Studio 2022. I went to the Help dropdown menu at the top of the Visual Studio window, and chose Check for Updates.
Then I followed the prompts to install the latest version, which was 17.5.4.
After these updates installed, I opened the solution again, and the solution loaded normally into Solution Explorer.
