Server vs Workstation GC

[Ryan Stevens]

Will a Windows Service exe written in C# use the Server or Workstation
version? Do I have to write a runtime host?

[Steven Pratschner [MS]]

Exe's always use the workstation. As you suggest, you must write a small
runtime host that loads the svr build and launches your app. Here's a
sample c++ app that I've been using. By the way, remember that the server
build will only be loaded on multi-proc machines - even if you specify "svr"
you'll get "wks" on uniproc.

#include "stdafx.h"

// needed for CorBindToRuntimeEx

#include <mscoree.h>

// include the tlb for mscorlib for access to the default AppDomain through
COM Interop

#import <mscorlib.tlb> raw_interfaces_only
high_property_prefixes("_get","_put","_putref")

using namespace mscorlib;

int _tmain(int argc, _TCHAR* argv[])

{

if (argc < 2)

{

printf("Usage: SvrHost <Managed Exe> [Arguments for Managed Exe]\n");

return 0;

}

ICorRuntimeHost *pCLR = NULL;

// Initialize the CLR. Specify the Server build

HRESULT hr = CorBindToRuntimeEx(

L"v1.1.4322",

L"svr",

NULL,

CLSID_CorRuntimeHost,

IID_ICorRuntimeHost,

(PVOID*) &pCLR);

assert(SUCCEEDED(hr));

// Start the CLR

pCLR->Start();

// Get a pointer to the default AppDomain

_AppDomain *pDefaultDomain = NULL;

IUnknown *pAppDomainPunk = NULL;

hr = pCLR->GetDefaultDomain(&pAppDomainPunk);

assert(pAppDomainPunk);

hr = pAppDomainPunk->QueryInterface(__uuidof(_AppDomain), (PVOID*)
&pDefaultDomain);

assert(pDefaultDomain);

// get the name of the exe to run

long retCode = 0;

BSTR asmName = SysAllocString(argv[1]);

// Collect the command line arguments to the managed exe

SAFEARRAY *psa = NULL;

SAFEARRAYBOUND rgsabound[1];

rgsabound[0].lLbound = 0;

rgsabound[0].cElements = (argc - 2);

psa = SafeArrayCreate(VT_BSTR, 1, rgsabound);

assert(psa);

for (int i = 2; i < argc; i++)

{

long idx[1];

idx[0] = i-2;

SafeArrayPutElement(psa, idx, SysAllocString(argv[i])); }

// Run the managed exe in the default AppDomain

hr = pDefaultDomain->ExecuteAssembly_3(asmName, NULL, psa, &retCode);

// clean up

SafeArrayDestroy(psa);

SysFreeString(asmName);

pAppDomainPunk->Release();

pDefaultDomain->Release();

_tprintf(L"\nReturn Code: %d\n", retCode);

return retCode;

}

Is it recommended that I run my C# service exe like this?

Does version 1.1 allow you to specify which GC to try?

Hmmm, good question, any comment on that?

There isn't any new functionality introduced in v1.1 that makes the
selection of the GC any easier or harder. If you want to use the server
build on v1.1, Steven's code example is the way to go.
