Advantages

• Does not depend on Operating System capabilities, only .NET framework functionality and a small number of NuGet packages.

Disadvantages

• Will fail if the selected port is already in use...
• ... Mitigation: register two or more separate applications with CCP using different ports for the redirect URL, if OWIN fails to bind to one port try the other port.
• May cause "Windows Firewall" warnings under some circumstances.
• ... Mitigation: warn the user in advance that Windows Firewall may display a message allowing.
• Client ID and Secret exposed to all users.
• ... Mitigation: None that I can think of.
