SMS and Call Integration in Asp.Net by Twilio API Services

July 17, 2014 2 min read

SMS API integration by Twilio API:

Twilio API is one of the best platforms for sending SMS and Automated calls through programming. Twilio API has excellent documentation and it has a .net wrapper developed using RestSharp. Sample codes are also available.

One of our projects had a requirement to have SMS notification be sent to a customer, So we wanted to integrate SMS with Twilio API in the Microsoft Asp.net Project. The only thing that we could not find is that our project Assembly needs to be installed in GAC(global assembly cache) and to install an assembly in GAC you must use a signed assembly. There are many tutorials on Google that explain how to sign an assembly using an SN.exe tool or Visual Studio.  but out of the visual studio using the ASP.net approach is the most reliable and has worked for me always.

Note: Singing assembly using Visual Studio will only work when you own source code, or Twilio API is open source.

In the case of Twilio, API source code is available on [GitHub](https://github.com/twilio/twilio-csharp), but that doesn’t solve the problem.

You must make sure that the assembly that is referenced in the Twilio API Project is be Signed assembly. So Now we will need Signed RestSharp.dll Assembly. The good news is that RestSharp is also available as open source package on [GitHub](https://github.com/restsharp/RestSharp) so all you have to do is First Create a signed assembly for RestSharp. then reference signed assembly in the Twilio Project. and then build solutions in release mode. that will output both signed assemblies in the Bin/release folder.

The following are ready to use signed assemblies:
