Hello,

I am creating a library in C# using SQLite. I would like to have not more than one (lib.dll) or two DLL (lib.dll and System.Data.SQLite.dll) in the end.

First I decided to use only the x86 version of the System.Data.SQLite.dll, however on the official website it's said [^]:

Using Native Library Pre-Loading
... Generally, x86 binaries will work on an x64 machine running Windows (using WoW64). However, there is a problem when using managed code. If the executable that starts the process consists entirely of managed code, it will run with the native processor architecture of the machine, which will be x64 on an x64 machine. ... 


So it seems to be important to also have a x64 version.

I saw things about the interop files (SQLite.Interop.dll), but they require subdirectories and more dll.

Consequently, I though about creating a x86 version of my library and a x64 version, with a different System.Data.SQLite.dll file for each.

I have the following questions:
- where can I find x64 and x86 versions of System.Data.SQLite.dll ?
- how can I compile them myself from source code?
- is there an easy way to have the System.Data.SQLite.dll file as an embedded resource, so I'll only have to distribute one dll in the end ?

Thanks for your help, please ask any questions if needed.

What I have tried:

I found some informations but I'm lost about the general procedure, and where I can find the files.

You cannot use a single dll for both x86 and x64.

This is not what I am asking for, I would like to have one dll for x64 and then create a x64 version of my library, and in an other projet, a dll for x86 and then create a x86 version of my library.

OK, so what is the problem?

Those questions can be answered at System.Data.SQLite Downloads Page[^].
