H5F.create() call throws BadImageFormatException

A VS 2017 console application (.NET 4.6.1 as target framework) running on a Windows 10 x64 PC throws following exception at call of the H5F.create(@"C:\mytest.h5", H5F.ACC_TRUN) method, if application built with the AnyCPU (or x86) option as platform target:

```
BadImageFormatException: An attempt was made to load a program with an incorrect format. (Exception from HRESULT: 0x8007000B)
```
It seems to work ok if application built with x64 as platform target.
Is this a normal behaviour?

Later edit: I tested my application also with HDF.PInvoke.NETStandard library instead of HDF.PInvoke. It has the same behaviour for AnyCPU, but it works with x86 (and x64).
