The type or name namespace "Tcp" does not exist (.NET Framework)

I have a problem. When using System.Runtime.Remoting.Channels.Tcp I get: "The type or name of the namespace "Tcp" was not found in the namespace "System.Runtime.Remoting.Channels"(link may be missing)".

For your information, if someone says: "write: using System.Runtime.Remoting;
using System.Runtime.Remoting.Channels;" Wrote, it didn't help.

I am using Visual Studio Community 2022 - 17.13.6, installed loads:
-Development of classic applications .NET
-Development using .NET Multi-Platform
-ASP.NET
Individual components:
-NET Framework (4.6.1 - 4.8)
-SDK packages for NET Framework 4.6.1 - 4.8)
-NET Runtime Environment 8.0
-NET Runtime Environment 9.0
-Development tools .NET Framework 3.5

(Sorry for the bad English)

It seems like you're facing an issue with the "Tcp" namespace within the ".NET Framework." The error message stating that "The type or name of the namespace 'Tcp' was not found in the namespace 'System.Runtime.Remoting.Channels'" indicates that the Tcp channel may not be available or accessible in your current setup.

Given that you've already included the necessary using directives for System.Runtime.Remoting and System.Runtime.Remoting.Channels, and considering your installation components, it appears that the Tcp channel might not be supported in the .NET Framework version you are using (4.6.1 - 4.8).

One potential solution could involve checking if there have been any changes or deprecations regarding the Tcp channel in the .NET Framework versions you have installed. It might be helpful to review the official Microsoft documentation for the specific .NET Framework versions you are using to confirm Tcp channel compatibility.

Alternatively, if the Tcp channel is no longer supported or has been replaced by alternative communication mechanisms, you may need to explore using different channels or technologies for your networking needs within your application.

If you provide more context about your application's requirements or the functionality you are trying to achieve using the Tcp channel, I can offer more specific guidance or alternative approaches that align with your goals. Feel free to share any additional details that could help in resolving this issue effectively.
