Hi,

I'm trying to use ILMerge to create a merged assembly, including both generic and DBSpecific projects, as well as the SD dlls, but get the following error trying to run a LINQ query.

MyProj.All is the merged assembly and is the only assembly referenced by my console application.

All the individual projects getting merged into MyProj.All have non-strong-name references to the SD dlls.

I've verified the same query works fine when referencing all dlls individually.

Any ideas before I go stepping through the source code?

Thanks!

Sorry, there is only one other reference to ILMerge on the forums, and it's not particularly relevant to your problem.

I've never used so can't really offer a lot of help - it's not something we recommend.

Can I ask WHY you want to do this ? I've never come across the need to munge all my dlls into one enormous one

Matt

Specifically, we want to do this because we redistribute our code as a component, referenced by other projects in our organization. To request these projects deploy all 15 or so dlls of our dlls is a huge deployment hassle. It's much easier to hand over a single dll and say "Here, reference this."

I also tried merging only the DBGeneric and DBSpecific dlls, but leaving the SD dlls unmerged and I experienced the same exception from my original post...so it seems to have something to do with those assemblies...

Thanks.

If you can live with just the DBGeneric and DB Specific in one dll, this can be accomplished by just adding all the files to one project, and building that.
