Adding binary library to the native code

Let's say I compile the following code and compile it to a library for the STM32F4

int GetValue(unsigned char* pBuffer,int nSize)
{
	int nIndex = 0;
	for(nIndex = 0;nIndex <nSize;nIndex++)
	{
			pBuffer[nIndex] = nIndex;
	}
	return nIndex;
}

The result is ExampleLib.lib

I then include it in the project file:

<DriverLibs Include="Solutions\NetduinoPlus2\DeviceCode\Example\Example\Stubs\ExampleLib.$(LIB_EXT)"/>

During compile the binary is linked and the firmware builds without any issues, I can deploy it to the Netduino
but as soon as we do it crashes. 

Am I missing something here?

Note: I know I could just include the source code instead, but I want to understand what it takes to include a binary directly
