clr.dll being loaded unexpectedly by InstrumentationEngine.Extensions.Base

Code that loads clr.dll (in extension base component of ApplicationInsights)

if (bstrModuleName == L"mscorlib.dll")
    {
        std::wstring strModulePath;
        IfFailRet(GetModulePath(strModulePath));

        std::shared_ptr<CModuleMetaDataLoader> spLoader;
        IfFailRet(CreateAndBuildUp(spLoader, strModulePath + ExtensionsBaseOriginalModuleName));

HRESULT CModuleMetaDataLoader::Load()
{
    HRESULT hr = S_OK;

    ATL::CComPtr<IMetaDataDispenserEx> pDisp;

    ATL::CComPtr<ICLRMetaHost> pMetaHost;
    ATL::CComPtr<ICLRRuntimeInfo> pRuntime;
    IfFailRet(CLRCreateInstance(CLSID_CLRMetaHost, IID_ICLRMetaHost, reinterpret_cast<void **>(&pMetaHost)));
    IfFailRet(pMetaHost->GetRuntime(L"v4.0.30319", IID_ICLRRuntimeInfo, reinterpret_cast<void **>(&pRuntime)));
    IfFailRet(pRuntime->GetInterface(CLSID_CorMetaDataDispenser, IID_IMetaDataDispenserEx, reinterpret_cast<void **>(&pDisp)));

The highlighted line causes the following dll’s to load, mentioned earlier in the thread:

Start in the InstrumentationEngine.Extensions.Base component at the bstrModuleName check and CModuleMetaDataLoader::Load, then inspect the CLRCreateInstance, GetRuntime, and GetInterface calls. Reproduce the load behavior with the ConsoleApplication9.exe context described in the report; the issue does not specify the desired behavior or a concrete completion condition.
