I have an assembly ComnAssembly.dll which is used by 3 applications.
In other words there are 3 solutions which include ComnAssembly.dll
project.

In order to avoid manual copying I use post-build event command line
inComnAssembly.dll project. The problem is that I can copy ComnAssembly.dll
only to one application location only, for example:

copy ComnAssembly.dll C:\FirstSolution\bin\Debug\ComnAssembly.dll

So my question is: How can I copy ComnAssembly.dll to multiple locations?
For example to:
C:\FirstSolution\bin\Debug\ComnAssembly.dll
C:\SecondSolution\bin\Debug\ComnAssembly.dll
C:\ThirdSolution\bin\Debug\ComnAssembly.dll

Thanks
