使用 /clr 或 clr:pure (cpprestsdk aka casablanca） 编译时不支持互斥

我在visual c++中创建了一个64 bit配置的CLR project，并尝试使用cpprestsdk aka casablanca 64bit .

但是当我运行该项目时，发生了错误：

1>------ Build started: Project: Timestamp, Configuration: Debug x64 ------

1>Generating Code...
1>Done building project "Timestamp.vcxproj" -- FAILED.
========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========

其他错误：

E2093   a local lambda is not allowed in a member function of a managed class   Timestamp   c:UsersLaptop-attendancesourcereposTimestampTimestampTestapi.h   97

IDE 显示有关.then函数中'['字符的错误，例如 .then([=](http_response response) ，如果您指出它，它会说"a local lambda is not allowed in a member function of a managed class"

如果我在具有 64 位配置的 Visual c ++ Windows Console Application中尝试该cpprestsdk，它可以正常工作。

我正在使用Visual Studio 2017。

你认为cpprestsdk不能用在vc++的CLR项目中吗？

谢谢。

这是我的代码，以及我刚刚从教程中得到的关于cpprestsdk的代码：
