Visual Studio 2022 - 'The project is not part of the solution' when trying to add an existing project to the solution
I'm refactoring my project and I'm stuck trying to I've been struggling with this for a few days now and could really use some help... This might be a silly question, but I'm using Visual Studio 2022 and trying to add an existing project to my solution, but I keep running into an scenario where it says 'The project is not part of the solution'. I have confirmed that the project is in the correct directory and is properly formatted. Here's what I've done so far: 1. Right-clicked on the solution in Solution Explorer and selected 'Add' -> 'Existing Project...'. 2. Navigated to the folder containing the project files and selected the `.csproj` file. 3. When I attempt to add the project, I receive the behavior message mentioned above. I've checked the path and ensured that the project file is not corrupted or locked by another process. The project I’m trying to add is a class library targeting .NET 6.0. Here’s what the `.csproj` file looks like: ```xml <Project Sdk="Microsoft.NET.Sdk"> <PropertyGroup> <OutputType>Library</OutputType> <TargetFramework>net6.0</TargetFramework> </PropertyGroup> </Project> ``` I also tried cleaning and rebuilding the solution, restarting Visual Studio, and even creating a new solution to see if the scenario continues, but I still encounter the same question. Has anyone else faced this or know any steps I might be missing? Any help would be appreciated! I'm working on a service that needs to handle this. Am I missing something obvious? Thanks for taking the time to read this! Could someone point me to the right documentation?
