Visual Studio 2022 - scenarios 'scenarios to load the project assembly' when using Roslyn Analyzers

visual-studio roslyn dotnet-6 analyzers C#

I tried several approaches but none seem to work. I'm relatively new to this, so bear with me. I'm working with an scenario in Visual Studio 2022 where I receive the behavior message 'Failed to load the project assembly' when trying to build my solution that includes Roslyn analyzers. This scenario arises after I upgraded to .NET 6 and updated several NuGet packages. I have verified that my analyzer projects target the same version of .NET as the main application, but the build fails with the aforementioned behavior. Here's a snippet from my `.csproj` file for the analyzer project: ```xml <Project Sdk="Microsoft.NET.Sdk"> <PropertyGroup> <TargetFramework>net6.0</TargetFramework> <OutputType>Library</OutputType> </PropertyGroup> <ItemGroup> <PackageReference Include="Microsoft.CodeAnalysis.Analyzers" Version="3.3.2" /> <PackageReference Include="Microsoft.CodeAnalysis.CSharp" Version="4.0.0" /> </ItemGroup> </Project> ``` I've also tried cleaning and rebuilding the solution, as well as restarting Visual Studio, but the behavior continues. When I attempt to run the build from the command line using `dotnet build`, it gives me a more detailed behavior: ``` behavior: The analyzer 'MyAnalyzer.dll' is not compatible with the current version of the compiler. ``` I've checked that the versions of `Microsoft.CodeAnalysis` packages are compatible, and I need to seem to pinpoint what might be misconfigured. Can anyone suggest what could be causing this scenario or how to resolve it? What am I doing wrong? My development environment is macOS. Any help would be greatly appreciated! For context: I'm using C# on macOS. Thanks in advance!
