Hi All,

A .Net target DLL generated with PB 2017 R2 is called from a web service. It is fast  and works as expected with a single web service request. With concurrent requests to the web service (two Users or more) the behavior is as follows:

 1. both requests are hanging and never finished and time out                           or

 2. when the second request hits the DLL the first request aborts and the second finishes properly

The web service is multi-thread and my understand is that the DLL should be instantiated for each request. However it seems to be shared.

Questions:

     1. Is a PB .Net Target generated DLL thread safe, so it can be invoked in a multi-thread environment?

Any suggestions or ideas on how to overcome this situation are welcome.

Thank you,

Paulo Gomes
