Close user sessions AXAPTA - asp.net

Question

im making a website who uses the Dynamics AX Business Connector to connect with AX, it´s working fine but sometimes the users don´t logout.
Here is my code:
Microsoft.Dynamics.BusinessConnectorNet.Axapta DynAx = new Microsoft.Dynamics.BusinessConnectorNet.Axapta();
try
{
DynAx.Logon(null, null, null, null);
//Execute some methods
DynAx.Logoff();
}
catch (Exception ex)
{
DynAx.Logoff();
}
and in ax i can see the users logged in. Again this happens sometimes, thats why i don´t know who may be.
Maybe Dispose() Method it's better?.
Thank you for taking your time to read this.

Answer 1

Logon/logoff works for me correctly, but if you're saying sometimes it doesn't, then the reason is most likely one of the following:
The business connector can be flaky. It's wasn't a Microsoft priority and eventually was depreciated.
Whatever is happening in your //Execute some methods section could be locking or preventing the logoff.
You may need to update your kernel to get an updated version of the business connector
In my AX2012R3 environment I can run the below PowerShell code over and over with success. This points me towards one of the above as a cause.
Add-Type -Path "C:\Program Files\Microsoft Dynamics AX\60\BusinessConnector\Bin\Microsoft.Dynamics.BusinessConnectorNet.dll"
$ax = new-object Microsoft.Dynamics.BusinessConnectorNet.Axapta
 
$ax.logon($null, $null, $null, $null)
$b = $ax.CreateAxaptaRecord("userinfo")
$array = New-Object System.Collections.ArrayList
 
$b.ExecuteStmt("select id from %1")
while($b.found){
$array.add($b.get_field("id")) | out-null
$b.next() | out-null
}
 
$array | Format-Table -AutoSize
$ax.Logoff()
$ax.Dispose()
