What causes System.BadImageFormatException when constructing System.Data.SQLite.SQLiteConnection
.net, 32bit-64bit, sqlite, system.data.sqlite
Solution
SQLite contains unmanaged code, you can't run it on a 64-bit operating system unless you deploy the 64-bit version. Quick fix: Project + Properties, Build tab, Platform Target = x86.
Problem
I've broken the code down to the smallest possible statement: ``` Dim cn As System.Data.SQLite.SQLiteConnection ``` And I get the following error when calling the code from a WinForm applicaiton: System.BadImageFormatException: Could not load file or assembly 'System.Data.SQLite, Version=1.0.65.0, Culture=neutral, PublicKeyToken=db937bc2d44ff139' or one of its dependencies. An attempt was made to load a program with an incorrect format. File name: 'System.Data.SQLite, Version=1.0.65.0, Culture=neutral, PublicKeyToken=db937bc2d44ff139' Yet calling the same piece of code from MS Unit Test I do not get the error, plus the full code set works as expected.
