Did you try double clicking the error or right click Go To?

If the error has a line number then you should always be able to Go To the code.

There are also mini buttons above the solution explorer that help with this. One of the buttons ensures the solution explorer auto-selects the file name that is active in the code editor, another of the buttons positions the explorer to the code editor when the button is clicked and another shows "All files" as opposed to the default "Filtered View". Show all files is physical disk/file view which more clearly shows the actual structure of your files.

Finally you can right click Code Editor tabs or Solution Explorer items to "Open Containing Folder" in windows explorer.

So you should be able to easily jump to an error in the code and clearly see the affected file?
