در ادامه باید بر روی Solution یک فایل جدید را به نام editorconfig. ایجاد کنید و تنظیمات مربوط به حداکثر کاراکترهای یک خط را وارد نمایید.

[*.{cs}]
guidelines = 80

در تنظیمات بالا مشخص شده‌است که در فایل‌هایی با پسوند cs. که همان فایلهای سی‌شارپ هستند، در کاراکتر 80، یک راهنما ایجاد شود تا زمانیکه توسعه دهنده به کاراکتر 80 رسید، متوجه شود باید در خط بعد ادامه کدهای خود را بنویسد. به صورت پیشفرض رنگ راهنمای ایجاد شده قرمز می‌باشد و برای تغییر رنگ آن باید در مسیر زیر

Tools > Options > Environment > Font and Colors > Guideline

 مقدار رنگ قرمز را به رنگ مورد نظر خود تغییر دهید. سپس اگر یک فایل با پسوند cs را باز کنید، در کاراکتر 80، نقطه چین ایجاد شده به صورت عمودی را مشاهده می‌کنید که برای راهنمایی شما ایجاد شده است تا کدهای شما بیشتر از 80 کاراکتر در یک خط نشود.

When we started the Google Code project hosting service in 2006, the world of project hosting was limited. We were worried about reliability and stagnation, so we took action by giving the open source community another option to choose from. Since then, we’ve seen a wide variety of better project hosting services such as GitHub and Bitbucket bloom. Many projects moved away from Google Code to those other systems. To meet developers where they are, we ourselves migrated nearly a thousand of our own open source projects from Google Code to GitHub.
