I just tried with the following,
Device.Net\Windows\ApiService.cs
#if NETFRAMEWORK
private const uint FILE_FLAG_OVERLAPPED = 0;
#else
private const uint FILE_FLAG_OVERLAPPED = 0x40000000;
#endif
Hid.Net\Windows\WindowsHidApiService.cs
#if NETFRAMEWORK
private const bool _isAsync = false;
#else
private const bool _isAsync = true;
#endif
public Stream OpenRead(SafeFileHandle readSafeFileHandle, ushort readBufferSize) => new FileStream(readSafeFileHandle, FileAccess.Read, readBufferSize, _isAsync);
public Stream OpenWrite(SafeFileHandle writeSafeFileHandle, ushort writeBufferSize) => new FileStream(writeSafeFileHandle, FileAccess.ReadWrite, writeBufferSize, _isAsync);
That seems to have fixed my issue not having anything written, only when including the net45 build, while the netstandard2.0 builds still have the same issue.

@andyvorld do you think it could be solved with #ifs?

@andyvorld does the same issue occur if you target .net 5?

@andyvorld you could submit a PR. I will probably do a new release fairly soon.

Using the nuget packaged 4.2.1, it works fine.

EDIT2: Sorry I forgot to clean the build cache, so there were some conflicts between the binaries, rebuilt my test script in .Net5 with the changes and it works find with _isAsync = True.
Ill make a pull request now with my edits.
I am not sure if I am using the compiled dlls as expected, as for my .Net 5 test, using the binaries from the standard2.0 output of HID.Net fails at run time, while the net45 binaries works.
Which after going through visual studio's debugger showed that the _isAsync flag in WindowsHidApiService is set to false, which would break the initially working functionality for .Net 5.
EDIT:
The specific error
System.MissingMethodException
HResult=0x80131513
