I am probably going to be using LLBLgen for a handheld application under development. However, the compiled Generic and Adapter assemblies, along with dependencies, are about 16.8 MB. When considering modem-speed syncs and that we need to update the assemblies often, this is just way too big.

I imagine that there are some options available to disable generation of parts of the generic code so that the entire assembly will be smaller. Can you point me in the right direction? What kind of size decrease can I expect?

How big is your app (how many entities, views, sp's..., how many winforms or webforms, how many resources files) ?

What TemplateSet (_Adpater | SelfServicing_) are you using?

Northwind app (in Adapter mode) final assemblies with their dependencies not exceed the 753,664 bytes. Also the GUI (With LLBLGen GUI Templates and all the bin necessaries) hold about 4.10 MB.

Also you can read the LLBLGenPro Help - Using the designer - Generating code - Task queue to execute tab, as you can disable some tasks you are not using (please be careful with this , always do a BK).

16MB suggests you have a truckload of entities in the project. Do you need all of them on the handheld? Probably not. So you could cut down the code a lot by simply removing entities from the project till you have the set you want to use on the handheld and generate code with these.
