I have Visual Studio Community 2022 version 17.8.6. I have downloaded and installed .NET SDK and runtime. The problem is, in a C# desktop project I try to use Queue<T>.TryDequeue(T) i get compiler error CS1060. The Method is not available. I assume I have the wrong version of Systems.Collection.dll. It is not visible in Project>Ada Reference>Assemblies. The list of available target frameworks in Project>Properties does not include .NET8 What can I do to solve this!

2024-02-09T15:05:43.5166667+00:00 Thank you for answering. It seems the Visual Studio Installer information I get is about the same as you have, although the UI is not exactly the same
looking at the project properties, It does not look quite like your image, still
.Net 8 is not listed. If I click "install other frameworks.." I get a webpage to install (or repair) .NET 8, which I have done. It has no effect on the list of Target framework. I have done art repair installation of Visual Studio. Perhaps I should make a complete uninstall - install? (The problem with TryDequeue is still there)

2024-02-09T15:12:57.8566667+00:00 You have not created a project for .Net, but have used a template for a .Net Framework project. That is why your project cannot Target .Net 8.0. you should create a new project with the appropriate template.

Still you might wonder what stops Microsoft from including TryDequeue in a WPF desktop application - so to speak.
