I have found the ability to call a C function in Paquet Builder, but it would be a great improvement for us if we were able to directly call into a .Net assembly and have similar access to Paquet builder variables.
Is there any way to do this already or any plans for the future?
This would require .net dependency and we try to avoid dependencies so that packages are stand-alone. Do you want to call an assembly from your installed .net application?
I was going to write some .Net code to perform a custom action (to extract a line of text from a file which defines the installation folder), which Paquet Builder is unable to do. This would be easier for me in C#, but in the end I had to write some custom C code to read the file data.
