Crash when using with unity

[SashelI]

Hi,

As this lib supports .netstandard 2.1, i figured i could use it with unity. But i encounter two errors :
If I just install the nuget package, i have this error when calling "loadMemDocument" : DllNotFoundException: pdfium assembly:<unknown assembly> type:<unknown type> member:(null)

So I imported the necessary dlls for Unity editor (winx64 pdfium), but then anotehr issue : Unity crashes completely with this trace :
