ترجیحا نوع Typescript را انتخاب کردم. البته در داخل فایل ts. امکان نوشتن جاوا اسکریپت هم هست. بعد از ایجاد پروژه اگر با تصویری شبیه به تصویر زیر روبرو شدید، در نتیجه تنظیمات نصب و راه اندازی به درستی صورت گرفته است.

اگر به قسمت solution explorer دقت کنید، فایلی به نام config.xml را مشاهده خواهید کرد. با کلیک بر روی این فایل، یک صفحه‌ی گرافیکی باز خواهد شد که این امکان را به شما می‌دهد که پلاگین‌های مورد نیاز خود، تنظیمات مربوط به نرم افزار تولیدی (مانند تنظیم ورژن ویندوزی که می‌خواهید app شما بر روی آن اجرا شود) و تنظیمات مربوط به هر یک از پلتفرم‌ها را به صورت مجزا در اختیار داشته باشید.

یک فایل index.html هم در قالب پیش‌فرض قرار داده شده که بعدا می‌توانید آن را تغییر دهید و یا صفحات دیگری را اضافه کنید. همان طور که در قسمت‌های قبل گفته شد، قرار است ما یک وب اپلیکیشن طراحی کنیم و آن را درون Container بومی Cordova بسته بندی کنیم. لذا محدودیتی برای استفاده‌ی از کتابخانه‌های مرتبط با CSS ، HTML و JavaScript  نداریم و در ادامه‌ی مقالات با مثال‌های متعددی از آن‌ها استفاده خواهیم کرد.

در فولدر scripts-->typeings-->cordova-->plugins  اینترفیس‌هایی که برای دسترسی به امکانات بومی دستگاه تلفن فعلا در Cordova پشتیبانی می‌شوند، قرار گرفته است.

برای استفاده از تکنولوژی‌های وب در محیط بومی دستگاه، در طی فرآیند کامپایل، Cordova یک اپلیکیشن را به وسیله دو چیز مهم که در زیر اشاره شده است، خواهد ساخت.

• یک اپلیکیشن با یک کامپوننت  WebView که با مرورگر یکپارچه شده است.
  
• یه سری از منابعی که در داخل فایل‌های اپلیکیشن وب ما قرار دارند.
  

برای یکپارچه شدن API‌های Cordova با وب پیج موجود، اندکی کد نیاز داریم که برای انکار لینکی شبیه لینک زیر را در فایل html خود استفاده می‌کنیم که فقط بعد از کامپایل وجود خارجی دارد؛ به صورت زیر:

<script src="cordova.js"></script>

در پایان هم برای فهمیدن اینکه API‌های Cordova در دسترس هستند، می‌توانیم رخداد مربوط به devicerady را مدیریت کنیم؛ به صورت زیر:

document.addEventListener("deviceready", onDeviceReady, false);
function onDeviceReady() { /* INIT */ }

برای مدیریت رخدادهای مربوط به pause و resume هم که نشان دهنده‌ی ادامه برنامه (خارج شدن از حالت pause) و حالت تعلیق هستند، می‌توان به شکل زیر عمل کرد:

 function onDeviceReady() {
            // Handle the Cordova pause and resume events
            document.addEventListener('pause', onPause, false);
            document.addEventListener('resume', onResume, false);

            // TODO: Cordova has been loaded. Perform any initialization that requires Cordova here.
        }

        function onPause() {
            // TODO: This application has been suspended. Save application state here.
        }

        function onResume() {
            // TODO: This application has been reactivated. Restore application state here.
        } 

حال قصد داریم پروژه‌ی خود را که قرار است یک متن ساده را نشان دهد، با استفاده از شبیه ساز اجر ا کنیم. برای این منظور از قسمت toolbar ویژوال استودیو ، Solution Platform خود را انتخاب کنید و سپس می‌توانید شبیه ساز مورد نظر خود را انتخاب کرده و برنامه را اجرا کنید. در اینجا محیط مورد نظر من اندروید است  و برای این منظور هم میتوانم از شبیه ساز Android Emulator یا Ripple استفاده کنم.  به دلیل سرعت کم شبیه ساز اندروید، می‌توانید شبیه ساز  YouWave را دانلود و اجرا کرده و در قسمتی که شبیه ساز را از toolbar ویژوال انتخاب می‌کردید، این بار گزینه‌ی Device را انتخاب کنید. بعد از کامپایل برنامه‌ی شما، فایل apk تولید شده بر روی شبیه ساز نصب خواهد شد و شما قادر خواهید بود آنرا اجرا کنید.

نتیجه‌ی نهایی 

 با شبیه ساز Ripple

http://www.codeproject.com/Articles/860150/Visual-Studio-and-Apache-Cordova 

نکته : وقتی پروژه را برای اولین بار اجرا می‌کنید شاید کمی طول بکشد تا نتیجه‌ی نهایی را ببنید و آن هم به دلیل این است که ویژوال استودیو  باید مجموعه‌ای از package  های مورد نیاز Cordova را دانلود کند.

در مقاله بعد با jQuery Mobile آشنا خواهیم شد و یک مثال برای کار کردن با آن در نظر خواهم گرفت.
