Exception: There was code at the end #7

Hi,

I get a "There was code at the end" exception when I try to create a PackerPlugin.

I assume the reason are the following callsignatures (they have one opening brace and two closing braces):

WcxWrapper.cs:
_callSignature = $"PackFiles ({packedFile}, {subPath}, {srcPath}, {flags.ToString()}) - {addList.Count} files)";
_callSignature = $"DeleteFiles ({packedFile}) - {deleteList.Count} files)";
