ASP.NET Core

<p>ASP.NET Core is an open-source modular web-application framework. It is a redesign of <a href="/facts/ASP.NET/xq7KM8mN">ASP.NET</a> that unites the previously separate <a href="/facts/ASP.NET_MVC/KFyeWXHx">ASP.NET MVC</a> and <a href="/facts/ASP.NET_Web_API/KFyeWXHx">ASP.NET Web API</a> into a single <a href="/facts/Programming_model/XhNua0XG">programming model</a>. Despite being a new framework, built on a new web stack, it does have a high degree of concept compatibility with ASP.NET. The ASP.NET Core framework supports side-by-side versioning so that different applications being developed on a single machine can target different versions of ASP.NET Core. This was not possible with previous versions of ASP.NET. ASP.NET Core initially ran on both the Windows-only <a href="/facts/.NET_Framework/J6QDAUhP">.NET Framework</a> and the <a href="/facts/Cross-platform/16zqdvNR">cross-platform</a> <a href="/facts/.NET/PDMQdfFu">.NET</a>. However, support for the .NET Framework was dropped beginning with ASP.Net Core 3.0.
</p><p><a href="/facts/Blazor/DflqmThl">Blazor</a> is a recent (optional) component to support <a href="/facts/WebAssembly/7ukwnxY9">WebAssembly</a> and since version 5.0, it has dropped support for some old web browsers. While current <a href="/facts/Microsoft_Edge/BGoJEFX9">Microsoft Edge</a> works, the <a href="/facts/Legacy_system/YvYjMcCz">legacy version</a> of it, i.e. "<a href="/facts/Microsoft_Edge/BGoJEFX9">Microsoft Edge Legacy</a>" and <a href="/facts/Internet_Explorer_11/EjgV0YJe">Internet Explorer 11</a> was dropped when you use Blazor.
