run program opengl in C# using framework Tao in 64 bits

I have a program opengl in C# using framework Tao, when i run the code in the platform target to x86, i have not a problem,but when i run the code in the platform target to x32, it stops abruptly and says the following

"An attempt was made to load a program with an incorrect format. (Exception from HRESULT: 0x8007000B)"

Advice what t开发者_开发技巧o do because i need to run my program in 64 bits

My gut feeling is that the Tao library is 64bit, if your program is compiled at 32bit, it can't link to 64bit lobs, even running on a 64bit machine. At least not without a thinking layer and you don't want that in a graphics loop.
