Desktop Bridge下LaunchFullTrustProcessForCurrentAppAsync调用失败（0x80010117）

问题场景 #

基于Desktop Bridge打包的Win32应用中，通过Microsoft WRL调用LaunchFullTrustProcessForCurrentAppAsync启动控制台应用时失败，异步回调返回HRESULT=0x80010117，错误提示：

Call context cannot be accessed after call completed. CallContext: [\LaunchFullTrustProcessForApp] ...

相关代码实现 #

using namespace Microsoft::WRL;
using namespace ABI::Windows::ApplicationModel;

void LaunchFullTrustApp() {
        ComPtr<IFullTrustProcessLauncherStatics> fullTrustProcessLauncherStatic;
        auto hr = RoGetActivationFactory(HStringReference(RuntimeClass_Windows_ApplicationModel_FullTrustProcessLauncher).Get(), __uuidof(fullTrustProcessLauncherStatic), &fullTrustProcessLauncherStatic);
        CheckHr(hr);

        auto onCompletedCallback = Callback<Implements<RuntimeClassFlags<ClassicCom>, IAsyncActionCompletedHandler, FtmBase>>(
            [](IAsyncAction* asyncInfo, AsyncStatus asyncStatus)
            {
                auto hr = asyncInfo->GetResults();
                CheckHr(hr); // hr = "0x80010117: Call context cannot be accessed after call completed. CallContext: [\LaunchFullTrustProcessForApp] ..."

                if (asyncStatus != AsyncStatus::Completed) { // asyncStatus = Error
                    return S_FALSE;
                }

                return S_OK;
            });


        ComPtr<IAsyncAction> launchAction;
        hr = fullTrustProcessLauncherStatic->LaunchFullTrustProcessForCurrentAppAsync(&launchAction);
        CheckHr(hr);

        hr = launchAction->put_Completed(onCompletedCallback.Get());
        CheckHr(hr);
    }

包清单配置 #

...
<Capabilities>
    <rescap:Capability Name="runFullTrust" />
</Capabilities>
...
<Extensions>
    <desktop:Extension Category="windows.fullTrustProcess" Executable="HelloWorld.exe" EntryPoint="Windows.FullTrustApplication" />
</Extensions>

错误原因 #

核心问题在于回调逻辑的执行顺序错误：在异步操作进入Error状态后，调用IAsyncAction::GetResults()会访问已被释放的调用上下文，从而触发0x80010117错误。当前代码先调用GetResults()再判断异步状态，导致错误场景下的无效访问。

修复方案 #

1. 调整回调逻辑顺序 #

先判断异步操作状态，仅当状态为AsyncStatus::Completed时才调用GetResults()，避免在错误状态下访问已释放的上下文。修改后的回调代码如下：

auto onCompletedCallback = Callback<Implements<RuntimeClassFlags<ClassicCom>, IAsyncActionCompletedHandler, FtmBase>>(
    [](IAsyncAction* asyncInfo, AsyncStatus asyncStatus)
    {
        if (asyncStatus != AsyncStatus::Completed) {
            // 获取错误代码并处理
            HRESULT errorHr;
            asyncInfo->get_ErrorCode(&errorHr);
            // 可添加错误日志、弹窗提示等逻辑
            return S_FALSE;
        }

        // 仅在成功完成时调用GetResults()
        auto hr = asyncInfo->GetResults();
        CheckHr(hr);

        return S_OK;
    });

2. 验证包清单配置 #

确保清单配置满足以下要求：

• 根元素必须包含rescap和desktop命名空间声明，示例：

  <Package
    xmlns="http://schemas.microsoft.com/appx/manifest/foundation/windows10"
    xmlns:rescap="http://schemas.microsoft.com/appx/manifest/foundation/windows10/restrictedcapabilities"
    xmlns:desktop="http://schemas.microsoft.com/appx/manifest/desktop/windows10"
    ...>
  

• windows.fullTrustProcess扩展中的Executable路径必须正确，指向包内控制台应用的相对路径（如控制台在子目录需写SubFolder\HelloWorld.exe）
• 确认runFullTrust权限已正确声明

3. 额外检查项 #

• 控制台应用必须与主Win32应用同属一个Appx包，且已被正确包含在包内
• 测试时需通过AppxPackage部署，不要直接运行未打包的exe文件
