CONVERSION ERROR: Code could not be converted. Details:

Please check for any errors in the original code and try again.
注意調用堆棧最底層的方法”RefactoringEssentials.CSharp.Converter.VisualBasicConverter.ConvertText(String text, MetadataReference[] references)”，通過這個方法，我們大致可以知道這是由一個名稱爲RefactoringEssentials的程序集實現的，google搜一下，可以找到https://github.com/icsharpcode/RefactoringEssentials這個網頁，不過我並沒有發現”RefactoringEssentials.CSharp.Converter.VisualBasicConverter.ConvertText(String text, MetadataReference[] references)”這個方法。我們查看下commits，可以發現這樣一條
Remove code for Code Converter in RE, Unit Tests and VSIX (basically returned it to state of release 3.2)
