A similar question would be "how do I debug my operating system". You don't, you keep your fingers crossed that it will give you a decent error code and message when you use it improperly.

To enable debugging of COM dlls you have to do the following:

要启用COM dll的调试，您必须执行以下操作：

Projects Settings of the .NET Project -> Debug -> "Enable unmanaged code debugging" has to be selected

必须选择.NET项目的项目设置 - >调试 - >“启用非托管代码调试”

Now you can attach an unmanaged debugger/debug into unmanaged dlls.

现在，您可以将非托管调试器/调试附加到非托管dll中。

To step into the source of the dll you need the appropriate pdb files and source files.

要进入dll的源代码，您需要相应的pdb文件和源文件。
