RE: Dynamic assembly loading
Are you running Silverlight 4 and don't need OOB support? Simple solution is the built in application library caching. For external dlls you may need to manually create the exmap. Also I saw you mention they were c1 controls, have you used their XAPOptomiser to trim out unused code instead? I've implimented dynamic assemble loading for an application based on the navigation framework, essentially load each page from a remote dll, it is really quite fiddly to setup and I don't recommend the pain but the model of only loading the code you need as you load that page makes a lot of sence.

RE: Dynamic assembly loading
John, you've mentioned some interesting subjects that I am not familiar with: application library caching and exmap; C1 XAPOptimiser. I'll run some searches on these topics. Loading by navigation might be overkill for my needs, but I would have tried to implement something like if I had complex app navigation. This app has only a handful of fixed screen views that you can jump between. I would urge myself (and everyone else) who is starting a new Silverlight app to remember right from the start that you might need to dynamically load bits of the app ... data, resources, assemblies, etc. Don't be lazy at the start, remember to bake-in some design so you can do this easily.

RE: Dynamic assembly loading
Absolutely worth looking at those options, It should have been extmap, MSDN article covers it well: http://msdn.microsoft.com/en-us/library/dd833069(VS.95).aspx Looks like C1 has an online version if you want to test their optomiser instead: http://demo.componentone.com/Silverlight/XapOptimizer/ If you or anyone is really interested in the load on demand based on the navigation framework I got all the ideas from here: http://www.davidpoll.com/2010/02/01/on-demand-loading-of-assemblies-with-silverlight-navigation-revisited-for-silverlight-4-beta/ John.

Dynamic assembly loading
Folks, after years of avoiding the need, I finally have to async load some large DLLs. I have two charting libraries to reference and their total size is causing slow app loading. I have placed the guilty DLLs in the ClientBin folder and I can see them async loading correctly. But ... how do I let them be referenced in the project for compilation, but keep them out of the app XAP file for deploy? I tried setting Copy Local = false for the two references, but that has no effect.

Re: Dynamic assembly loading
Have a look at this http://development-guides.silverbaylabs.org/Video/Dynamically-Loading-.Dlls-in-Silverlight It seems to cover how I started off doing it on a project last year. I started off copying how Prism does it (it's a pattern with some helper dll's essentially) and then later we swapped in the Prism helpers. That was pretty easy as I'd named everything closely with Prism. So you can do it yourself or use a framework such as Prism. I've heard it said Prism is quite large/bloated compared to some other frameworks. I've not yet had a chance to look at the others, I like to do things myself until the need arises to use someone elses framework. Its a double edged sword, it does what you want but comes with their bugs. I'll be looking at MVVM lite over the next few weeks. May even do a demo at next Perth Silverlight user group.

RE: Dynamic assembly loading
I have seen problems in the past with copy local, particularly with using msbuild. It goes like this: Assembly B.dll depends on Assembly A.dll Assembly C.dll also depends on Assembly A.dll and Assembly B.dll B - A has copy local = true C - A has copy local = false When compiling a solution using msbuild, Assembly A.dll appears in the compiled output of both B and C. The copy local setting should exclude your assembly from the xap, but the build process might be getting confused with multiple copy local settings. If you set the build output level to verbose you may be able to diagnose why your assembly is being copied to the output.
