load_assembly_and_get_function_pointer_fn ptr getting failed

[yashnikam]

I am trying to call managed code from native, but load_assembly_and_get_function_pointer_fn getting failed with following error Failed to load assembly or get function pointer. Error code: 0x80070057

code snippet:

const string_t dotnetlib_path = STR("/home/yash/code/nativehost/MyDotNetLib/bin/Debug/net7.0/MyDotNetLib.dll");
const char_t *dotnet_type = STR("MyDotNetLib.MyClass, MyDotNetLib");
const char_t *dotnet_type_method = STR("Hello");

typedef void (*HelloDelegate)();
HelloDelegate hello_delegate = nullptr;
rc = load_assembly_fn(dotnetlib_path.c_str(), dotnet_type, dotnet_type_method, nullptr, nullptr,(void**)&hello_delegate);

if (rc != 0 && hello_delegate == nullptr) {
    std::cerr << "Failed to load assembly or get function pointer. Error code: " << std::hex << std::showbase << rc << std::endl;
    
    return false;

Csharp code:

using System; using System.Runtime.InteropServices; namespace MyDotNetLib { public static class MyClass { public static void Hello() { System.Console.WriteLine("hello"); } } }
