</span>Hello,<br>
<br>
I’m experiencing a rather weird issue when using the ESL libraries for .NET.<br>
<br>
When running the below code outside of Visual Studio in its own executable(Console Application) I’m receiving the below exception.<br>
When the code is run inside Visual Studio, it works perfect.<br>
<br>
Using ESL library contained in Freeswitch 1.2.13.<br>
<br>
Unhandled Exception: System.AccessViolationException: Attempted to read or write protected memory. This is often an indication that other memory is corrupt.<br>

</span><br>
Does anyone know why this is happening? Maybe someone can reproduce the problem on their own PC using the above code example.
<br>
<br>
Thank you!<br>
<br>
