nuget - C# and PInvoke into 32/64 bit DLL -

this question has answer here:

• target 32 bit or 64 bit native dll depending on environment 3 answers

i creating class library, hope put on nuget eventually. right now, targeting anycpu.

i want pinvoke dll, comes in both 32 , 64 bit versions. initially, thought i'd use 32 bit version, threw badimageformatexception. changed library target x86 only, , while works, requires caller 32 bit process too. naturally wouldn't work nuget project.

appreciate thoughts on how work 32/64 bit versions of native library, , how package in nuget (prefer not have 2 different assemblies).

you can check platform @ runtime , pinvoke different dlls.

static void nativefuncwrapper(){     if(environment.is64bitprocess){         nativefuncwrapper64(); //this calls 64-bit dll     }else{         nativefuncwrapper32(); //this calls 32-bit dll     } } 

if want work without environment.is64bitprocess, read how know process 32-bit or 64-bit programmatically alternative methods.
