问题
I am attempting to register a .dll using RegAsm. It is a .NET 2.0 dll. All classes are public and ComVisible is true. I am still getting the RA0000 : No types were registered error. Below is the code and assemblyinfo. Any help would be great, thanks!

I think your problem is you have no default constructor. Please add the following code and call. This is based on guidance from MSDN.
Calling Code (Will look different in COM of course)
var connection = new STARConnection();
connection.Initialize(username, password, loginTimeout, overallTimeout);
New Code
/// <summary>
/// Default constructor needed for COM. Set parameters with properties.
/// </summary>
public STARConnection()
{
}
public Initialize(string username, string password, int loginTimeout, int overallTimeout)
{
output = "";
conn = new TelnetConnection("HOSTHOSTHOST", 23);
this.SetTimeout(overallTimeout);
try
{
output = conn.Login(username, password, loginTimeout);
if(output.Contains("You entered an invalid login name or password"))
{
throw new LoginException("Failed to login");
}
this.ParsePrompt();
}
catch(Exception e)
{
if(e.Message.Contains("login prompt"))
{
throw new PromptException("Login", "Could not find login prompt");
}
else if(e.Message.Contains("password prompt"))
{
throw new PromptException("Password", "Could not find password prompt");
}
else
{
throw e;
}
}
}
