CSS isolation simplifies an app’s CSS footprint by preventing dependencies on global styles and helps to avoid styling conflicts among components and libraries.

In this post, we’ll look at how we can use one of the most popular libraries, React, to build a foldable web experience.

• اگر پروژه از جنس Library باشد، فایل csproj را به شکل زیر درآورید: 

<Project Sdk="Microsoft.NET.Sdk">
    <PropertyGroup>
        <TargetFramework>net472</TargetFramework>
        <OutputType>Library</OutputType>
    </PropertyGroup>
.
.
.
</Project>

• اگر پروژه از جنس Console باشد، فایل csproj را به شکل زیر درآورید:

<Project Sdk="Microsoft.NET.Sdk">
<PropertyGroup>
<TargetFramework>net472</TargetFramework>
<OutputType>Exe</OutputType>
<ApplicationIcon>logo.ico</ApplicationIcon>
<AppConfig>App.config</AppConfig>
</PropertyGroup>

• اگر پروژه از جنس Web باشد، فایل csproj را به شکل زیر درآورید. احتمالاً پیچیده‌ترین و سخت‌ترین فایل‌ها، متعلق به پروژه‌های وب باشد. اگر دقت کنید نوع SDK از نوع MSBuild.SDK.SystemWeb می‌باشد. نسخه این SDK ممکن است در زمانیکه شما در حال خواندن این مطلب می‌باشد آپدیت شده باشد و بهتر است قبل از استفاده، آخرین نسخه را از نیوگت برداشت کنید. (باید ذکر کنم که این hack کوچک را از یک comment  در issueهای گیت‌هاب پیدا کردم.)
