如何在Visual Studio 17中有效地更改TextMate语法

Question

我正在为我的语言（结构化文本）的高语法开发一种文本伴侣语法。 在编写* .tmLanguage文件之前，我已经在互联网上进行了大量研究，并且发现了其他语言定义文件的位置：

%userprofile%\.vs\Extensions

在这里，我已经在plc.tmLanguage中创建了文件夹（“ plc \ syntaxes”）。 该文件包含以下代码：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" 
"http://www.apple.com/DTDs/PropertyList-1.0.dtd">

不幸的是，当我打开Visual Studio时，没有任何变化，并且代码没有着色。 错误在哪里？也许范围selecotors？ 请我帮忙！
