I had to disable a SonarSource analyzer and made use of the new Lock type, see separate Commits.

CI is expected to fail because of missing .NET 9 binaries in AppVeyor. Build and tests pass locally.

Can be merged when .NET 9 final is released and AppVeyor supports it.

Can we have a basic Lock polyfill to save on the #ifdefs? e.g.

#if !NET9_0_OR_GREATER

namespace Renci.SshNet.Common;

internal sealed class Lock
{
    public bool TryEnter() => Monitor.TryEnter(this);
    public void Exit() => Monitor.Exit(this);
}

Makes sense, pushed.

@mus65, you'll also want to update global.json.

@Rob-Hague, are planning on merging this before the release of .NET 9.0? In theory, there may even be API changes - I'm thinking of the Lock class - between now and the release. It's highly unlikely though.

@drieseng @Rob-Hague I updated global.json . I had to reference RC1 explicitly though, so I have to change it when final is released.

I left it a draft because it's still preview and wouldn't expect it to be merged before .NET 9 final. RC1 is already released, so I wouldn't expect any more API changes.

Yeah, we will merge once .NET 9 is released

Newer targets can be used on appveyor with apt-get, as in the opposite of #1352

for some reason this happens starting with .NET 9.0 RC2:

/home/mus/git/SSH.NET/test/Renci.SshNet.IntegrationTests/Renci.SshNet.IntegrationTests.csproj : error NU1605:
      Warning As Error: Detected package downgrade: BouncyCastle.Cryptography from 2.4.0 to 2.3.1. Reference the package directly from the project to select a different version.

This is now only blocked by AppVeyor not supporting .NET 9. apt-get is not going work either because the dotnet9 package is not available in Ubuntu 22.04 (see https://launchpad.net/ubuntu/+source/dotnet9 ).

@Rob-Hague has there been any thought about moving to GitHub actions?

I seem to remember @WojciechNagorski trying it but I can't find a PR so may be imagining
