+# WixToolset.WixStandardBootstrapperApplicationFunctionApi
+
+WixToolset.WixStandardBootstrapperApplicationFunctionApi contains the SDK for building **BAFunctions** extensions for WixStdBA, the WiX Standard Bootstrapper Application for Burn bootstrapper bundles.
+
+BAFunctions are native-code DLLs (typically written in C++) that let you supplement the behavior of WixStdBA, rather than writing an entirely new BA to tweak existing BA behavior.

+# WixToolset.Sdk
+
+The `WixToolset.Sdk` package provides the WiX Toolset as an MSBuild SDK for both .NET (v6 or later) and .NET Framework (v4.7.2 or later). SDK-style projects have smart defaults that make for simple .wixproj project authoring. For example, here's a minimal .wixproj that builds an MSI from the .wxs source files in the project directory:
+
+```xml
+<Project Sdk="WixToolset.Sdk/5.0.0">
+</Project>
+```
+
+For more information about WiX as an MSBuild SDK, see https://wixtoolset.org/docs/intro/#msbuild.
+
+For more information about WiX targets, properties, and items, see https://wixtoolset.org/docs/tools/msbuild/.
