Unresolved assembly reference

Sometimes you'll get “Unresolved assembly reference not allowed” when attempting to use ILMerge. To avoid this, specify the full path to the framework you're targeting, like this:

ilmerge /targetplatform:v4,"C:WindowsMicrosoft.NETFramework64v4.0.30319" /out:merged.exe myprogram.exe mylib1.dll mylib2.dll
