Visual Studio 2019 - VSIX 설치 시 "The extension cannot be installed to this product due to prerequisites that cannot be resolved." 오류 발생
XmlCodeGenerator 도구를 Visual Studio 2019 Preview에 설치하는 데 다음과 같이 회색 처리가 되어 있습니다.
This extension cannot be installed to this product due to prerequisites that cannot be resolved.
반면, 로컬에 가지고 있던 vsix 파일을 직접 실행했더니 이번에는 아예 다음과 같은 오류 창이 뜹니다.
Some modifications could not be applied successfully. For more information, click on the install log link at the bottom of the dialog.
XmlCodeGenerator
This extension cannot be installed because the following references are missing: Microsoft.Net.ComponentGroup.TargetingPacks.Common
이때의 로그를 보면 다음과 같은 내용을 담고 있습니다.

그러니까 결국, Microsoft.Net.ComponentGroup.TargetingPacks.Common 어셈블리에 대한 참조가 Visual Studio 2019 Preview 버전에서는 없다는 것입니다.
해결 방법은 의외로 간단했습니다. 해당 의존성은 source.extension.vsixmanifest 파일에 다음과 같이 명시되어 있었는데,
<?xml version="1.0" encoding="utf-8"?>
<PackageManifest Version="2.0.0" xmlns="http://schemas.microsoft.com/developer/vsx-schema/2011" xmlns:d="http://schemas.microsoft.com/developer/vsx-schema-design/2011">

</PackageManifest>"]"
Version 설정에서 세부 버전에 대한 의존성을 없앴습니다.
