Add two VS2015 projects for CSharp: SWIG binding builder & sample app

[nanangizz]

Using swig_csharp_pjsua2.vcxproj for generating SWIG binding files

1. As we are generating a DLL, set the PJPROJECT solution config to "Debug-Dynamic" or "Release-Dynamic".
2. Add any third-party dependency in the library search path in the project setting, e.g: libh264 library path.
3. Make sure swig.exe is in the system path.
4. Build. This should generate .cs files and pjsua2.dll in pjsip-apps/src/swig/csharp/output/.

Using the sample app SimplePjsua2CS

1. Copy the SWIG generated .cs files (currently ~271 files) to folder pjsip-apps/src/swig/csharp/sample/SimplePjsua2CS/pjsua2/.
2. Add reference to pjsua2.dll in the SimplePjsua2CS project.
3. Run.

Troubleshooting

• Error TypeInitializationException in running and there is build warning There was a mismatch between the processor architecture of the project being built "MSIL" and the processor architecture of the reference "pjsua2".
  Usually this can be solved by setting platform target in SimplePjsua2CS properties (in Build > General > Platform target) to match to the CPU config used to build the PJPROJECT.

I followed the steps you said.
It created all the cs files and also created some other files named pjsua2.exp, pjsua2.lib, pjsua2_wrap.cpp but did not create the pjsua2.dll file. What should I do?
Also, I get another 185 error in Visual Studio after building the solution. But even with these errors, it creates cs files.

Can you upload and post pjsua2.dll separately? No matter what I do it doesn't give me the pjsua2.dll file.

@aparsaeeyan
We could resolve the linking errors by excluding the ignored libraries. However, we are unaware of any valid reason for excluding 'msvcrt.lib'.
