Meh, just spin up your own CLR host and run what you need to:

#include <mscoree.h>
#include <stdio.h>
#pragma comment(lib, "mscoree.lib") 

void Bootstrap()
{
    ICLRRuntimeHost *pHost = NULL;
    HRESULT hr = CorBindToRuntimeEx(L"v4.0.30319", L"wks", 0, CLSID_CLRRuntimeHost, IID_ICLRRuntimeHost, (PVOID*)&pHost);
    pHost->Start();
    printf("HRESULT:%x\n", hr);

    // target method MUST be static int method(string arg)
    DWORD dwRet = 0;
    hr = pHost->ExecuteInDefaultAppDomain(L"c:\\temp\\test.dll", L"Test.Hello", L"SayHello", L"Person!", &dwRet);
    printf("HRESULT:%x\n", hr);

    hr = pHost->Stop();
    printf("HRESULT:%x\n", hr);

    pHost->Release();
}

int main()
{
    Bootstrap();
}
