VS2013 generating events, removing unnecessary DLLs

A project in the solution is a Windows Service that is used to remove events from the message queue and send notification emails;

The UI is an MVC site, and two project references the same class library, which references third-party generated PDF component Pechkin;

Every time I build a website, Pechkin's 7 DLLs are automatically copied to the Bin directory, 7 DLLs add up to 30 megabytes, and the Web site runs with an error (Modify IIS application pool can be resolved), every time I debug the site, To manually remove these DLLs from the bin directory is inefficient ,

In fact, only Windows Services project used to Pechkin, the site does not need, so I think of the VS generation event, under the build event through the macro command to automatically delete these DLLs, I did this

Right-click property on site = "Generate Event

$ (TargetDir) is the output directory, is the site's Bin directory, more command parameters can be clicked "Macros";

If EXIST to determine whether there is a file, a conditional judgment statement, do not change line;

DEL is to delete one or more files.

if EXIST $ (TargetDir) Pechkin.dll del $ (TargetDir) Pechkin.dll IF EXIST $ (TargetDir) Pechkin.Synchronized.dll DEL $ ( TargetDir) Pechkin.Synchronized.dll if EXIST $ (TargetDir) Libeay32.dll DEL $ (TargetDir) Libeay32.dll if EXIST $ (TargetDir ) libgcc_s_dw2-1. dll DEL $ (TargetDir) libgcc_s_dw2-1.DLL IF EXIST $ (TargetDir) Mingwm10.dll DEL $ (TargetDir) Mingwm10.dll if EXIST $ (TargetDir) Ssleay32.dll DEL $ (TargetDir) Ssleay32.dll if EXIST $ (TargetDir) Wkhtmltox0.dll DEL $ (TargetDir) Wkhtmltox0.dll
