Unexpected exceptions on CloseConnection()

[PowerUser]

Hi!
I've got a strange issue with the Lightstreamer .Net Client.
When I'm trying to close connection I've got the following exceptions:

• A first chance exception of type 'System.InvalidOperationException' occurred in System.dll
• A first chance exception of type 'System.InvalidOperationException' occurred in System.dll
• A first chance exception of type 'System.Threading.ThreadAbortException' occurred in System.dll
• A first chance exception of type 'System.Threading.ThreadAbortException' occurred in System.dll
• A first chance exception of type 'System.IO.IOException' occurred in System.dll
• A first chance exception of type 'System.IO.IOException' occurred in System.dll
• A first chance exception of type 'System.IO.IOException' occurred in System.dll
• A first chance exception of type 'System.IO.IOException' occurred in System.dll
• A first chance exception of type 'System.IO.IOException' occurred in System.dll
• A first chance exception of type 'Lightstreamer.DotNet.Client.PhaseException' occurred in DotNetClient_N2.dll
• A first chance exception of type 'System.Threading.ThreadAbortException' occurred in DotNetClient_N2.dll
• A first chance exception of type 'System.Threading.ThreadAbortException' occurred in DotNetClient_N2.dll

Steps to reproduce:

1. Run sample project under Visual Studio (https://docs.google.com/uc?authuser=...xport=download)
2. Click "Connect" button to open connection
3. Click "Disconnect" button to close connection => see Output console

What I'm doing wrong? Is there any way to fix this issue?

I confirm that the three exceptions, among the ones listed, related to Lightstreamer libraries are a normal step in the disconnection operation.
The exceptions are properly caught inside Lightstreamer library.
The log of the exceptions at the time of throwing is a Visual Studio feature.
