I'm trying to call NtGetContextThread from C# on AMD64. The problem is that the CONTEXT structure for AMD64 needs to be aligned on a 16-byte boundary, and when I call NtGetContextThread I always get STATUS_DATATYPE_MISALIGNMENT. I'm aware that C# can align individual members of a struct using the Pack attribute, but it doesn't seem to be...
