Hi,
We are developing a product, it has lof ot features / modules. It's upto the user's wish like during Deployment they may purchase a feature / module. If they have purchased the feature only the module has to be deployed and the application should be integrated with that. Provide me with the suggestions and solutions to implement this.

Modularized Deployment

It seems like your challenge is more toward to license issue then deployment issue.
The deployment solution/suggest should be vary depends on the license solution that you may choose.
One simple thing is you can have different license token for different dll (which provide key functionality for that module). Once user purchase the license for that dll then you can put them in the license location. (I assuem you are using local licensing solution). Then using on-demand API to let users to download that dll.
In any case you may want to talk to license folks if you didn't already done so
Thanks
