Thanks Dave, Thanks Peter. Right after getting Peter's reply, I told management here that we should upgrade to VS2012, so that's what I'm using now. I'm to the point where FreeSWITCH is looking for my mod_managed script, but I don't know how to create one. The documenation says, "mod_managed should "just work" with the .NET Framework 3.5 and Visual Studio 2008 installed. In the build configuration manager inside Visual Studio, mod_managed has configurations for both Debug/Release CLR and Mono. Simply select Debug_CLR and build." I don't see any "build configuration manager". Is this different in VS2012? I cannot figure out how to load the FreeSWITCH libraries in my application. Again, any help would be appreciated.
