Web Deployment Project Error

[Bobby Edward]

When I build my web deployment project I get this error:

An error occurred when merging assemblies: ILMerge.Merge: ERROR!!:
Duplicate type 'MasterPage' found in assembly 'App_Web_yarpwypi'.

The "File" is aspnet_merge in the "Error List" window.

I built this website deployment project fine yesterday. Today I made very
MINOR changes to some HTML tables (unrelated to master files or code.)

I only have 2 master files in the whole project (MasterPage.master and
Admin\Admin.master). I have no duplicate class names.

Any ideas?

I changed the output to verbose. Here's my output...
