Every so often when i go to compile my Setup projects, i suddenly get
these errors:

The only workaround i have found is to create a new setup project from
scratch, which is becoming a serious pain as this happens about every
other day.

Does anyone know what is going on here? How can i fix it without
starting over with the project?

Solution:

1. Open File System view, browse to deployment folders where DLL's are
mistakenly referenced. They should be underlined with a blue squiggly
line.

2. For each mis-referenced DLL, select it, then in the properties
window set the Exclude property to True.

3. Rebuild the project.

4. Repeat process again in 2 days
