I’ve done some research on this problem and have seen a handful of possible solutions, but nothing that has worked for me.
Could not load file or assembly ‘System.Data.SQLite.dll’ or one of its
dependencies. The specified module could not be found.
I have a WPF application that uses SQLite. On my development machine (Windows 7, 64-bit, Visual Studio 2010), everything works just fine. Over in the QA department, everything works fine. But on the build machine (Windows Server 2008, 64-bit) and over in customer service (32-bit), it gives the error.
My .sln consists of 3 projects – two .exe and one lib (used by both .exe projects and containing the SQLite logic). All 3 have 2 configurations, Debug and Release, and each version compiles to x86. The SQLite dll is in the execution directory.
I have 3 System.Data.SQLite entries in my GAC, which has been verified as why I’m having success on my computer but not certain others, not that I know why it wouldn’t be using the dlls found in the executing directory. All GAC entries are version 1.0.66.0, have the same public key token, and are associated with MSIL, x86, and AMD64, respectively. Removing the files from the GAC allowed me to reproduce the error until I changed the project references to “copy local,” at which time it again worked on my computer (and still not on the others).
Not sure how smart this was, but I decided to attempt a dynamic load of the dll (while still using references in my projects), checking whether I was running in a 32-bit or 64-bit environment, and using Assembly.LoadFrom to load the SQLite dll for the correct bits. That code executes successfully and goes for the 32-bit version on my 64-bit machine, which I assume is because of the x86 compile platform. Regardless, it hasn’t changed the error I see on the other machines.
Suggestions as to how to resolve this issue?
edited: reflect results after removing references from the GAC
I had the same problem in the past. I build to versions: one referencing System.Data.SQLite x32 and the other x64.
