+# ASP.NET Core Web SDK
+
+### Overview
+
+`Microsoft.NET.Sdk.Web` is a [MSBuild project SDK](https://docs.microsoft.com/visualstudio/msbuild/how-to-use-project-sdk) for building ASP.NET Core apps. It's possible to build an ASP.NET Core app without this SDK, however, the Web SDK is:
+
+* Tailored towards providing a first-class experience.
+* The recommended target for most users.
+
+Use the Web.SDK in a project:
+
+  ```xml
+  <Project SDK="Microsoft.NET.Sdk.Web">
+    <!-- omitted for brevity -->
+  </Project>
+  ```
+
+Features enabled by using the Web SDK:
+
+* Projects targeting .NET Core 3.0 or later implicitly reference:
+
+  * The [ASP.NET Core shared framework](xref:fundamentals/metapackage-app).
+  * [Analyzers](xref:https://docs.microsoft.com/visualstudio/extensibility/getting-started-with-roslyn-analyzers) designed for building ASP.NET Core apps.
+* The WebSDK enables MSBuild targets that enables the use of publish profiles, and publishing using WebDeploy.
+
+### Properties
+
+| Property | Description |
+| -------- | ----------- |
+| `DisableImplicitFrameworkReferences` | Disables implicit reference to the `Microsoft.AspNetCore.App` shared framework. |
+| `DisableImplicitAspNetCoreAnalyzers` | Disables implicit reference to ASP.NET Core analyzers. |
+| `DisableImplicitComponentsAnalyzers` | Disables implicit reference to Razor Components analyzers when building Blazor (server) applications. |
