[Freeswitch-users] ESL and Event Socket for .NET

[Grant Bagdasarian]

​I fixed it. The ESL.DLL library was being loaded just fine but the MSVCR110.DLL could not be found, which is apparently used by the ESL.DLL.


Make sure to install the Visual C++ Redistributable for Visual Studio 2012 Update 4.

Is it built against the debug c runtime lib?

I used procmon.exe to monitor the executable and which files it loads. It showed it loaded the ESL.DLL successfully.
I even made the user administrator on the server, but that didn’t work either.

After searching the internet for a while, I came across this: https://github.com/danbarua/NEventSocket
This guy made a pretty neat .NET API using Rx and no use of ManagedEsl, ESL.DLL. I didn’t know that was possible.
The ESL libraries have given me a lot of trouble ☹.

My best guess is that it is a permissions problem, either the FS process can’t access the directory or the file itself.

Hello,

This seems to be a very old thread, but I’m experiencing the same error like the one below.
I’m using the ManagedEsl and ESL.dll from 1.4.15. I’ve compiled both myself and they work on my development machine.
The application is contained in a Windows Service, and when installed on a production server as a Service, I get the same error “Unable to load DSLL ‘ESL’”….

I ran procmon.exe to see if the application executable could find the ESL.dll, and it could, so I don’t know why this error occurs.

Any ideas?

Grant

Dave -

Can you compile a new version? I tried with VS 2013 and get the following error when running my application:
