2019 버전까지 잘 동작하던 아래의 코드가,
Property property = dte.DTE.get_Properties("TextEditor", "PlainText").Item("IndentStyle");
// 또는
Property property = dte.DTE.Properties["TextEditor", "PlainText"].Item("IndentStyle");
2022 버전에서 (예외 정도가 아니라) crash가 발생합니다.

MissingMethodException 예외가 힘든 것은, 해당 메서드가 위치한 라인을 알려주는 것이 아니라 그것을 포함한 메서드만을 알려주기 때문입니다. 그래서 어떤 메서드의 부재로 예외가 발생하는지 알 길이 없습니다. 이걸 알려면 디버거를 걸거나, print 식 디버깅을 해야 합니다.
그런데 문제를 알아도 이런 식으로 수정하면 안 됩니다.
void SetTextAsync()
{
Property property = null;
Version version = new Version(dte.Version);
if (version.Major <= 16) // 2019 이하 버전에서만 코드 실행!
{
property = dte.DTE.Properties["TextEditor", "PlainText"].Item("IndentStyle");
}
}
왜냐하면, if 문에 상관없이 (문제가 발생한 메서드인) SetTextAsync를 JIT 컴파일할 때 MissingMethodException 예외가 발생하기 때문입니다. 따라서, 해당 코드를 JIT 순간에 방해가 되지 않도록 별도의 메서드로 분리해내야 합니다.
void SetTextAsync()
{
Property property = null;
Version version = new Version(dte.Version);
if (version.Major <= 16) // 2019 이하 버전에서만 코드 실행
{
property = GetIndentStyle(dte);
}
}
private static Property GetIndentStyle(DTE2 dte)
{
Microsoft.VisualStudio.Shell.ThreadHelper.ThrowIfNotOnUIThread();
return dte.DTE.Properties["TextEditor", "PlainText"].Item("IndentStyle");
}
검색해 보면,
Missing EnvDTE Properties for Debugging -> Symbols
; https://developercommunity.visualstudio.com/t/missing-envdte-properties-for-debugging-symbols/193262
동일한 증상인데,
EnvDTE.DTE dte = ServiceProvider.GetService(typeof(EnvDTE.DTE)) as EnvDTE.DTE;
dte.Properties["Debugging", "General"].Item("EnableJustMyCode").Value = true;
"Debugging" 부분은 별도로 IVsDebuggerSymbolSettings120A / IVsDebuggerSymbolSettingsManager120A 인터페이스로 기능을 대체한 듯합니다. 이 글에서 문제가 된 TextEditor도 대체 인터페이스가 있을 듯한데 글쎄요... 테스트해 봐야 알겠지만 아래의 정도가 후보군이 될 수 있겠군요.
