Hello Chris,

Did you used Nuget? Normally nuget package will inject code in your csproj file and VS will copy automatically necessary lmdb dll files. However sometimes it seems it fail. So please copy manually lmdb32.dll and lmdb64.dll in your /bin folder and the problem will be fixed.

Both lmdb32.dll and lmdb64.dll are in the bin folder. It's returning a badformat exception not a can't find exception.

[Siaqodb Support]

Can you send us a sample project(including /bin and /obj folders) to :support at siaqodb dot com ?

Thx!

Cristi
