SignalR C++ Client read access violation from signalr_client_config destructor

[ChrisHawkridge]

Hi there,

I am getting a read access violation as soon as an instance of signalr_client_config goes out of scope.
I pulled the microsoft-signalr package from vcpkg and I am using Visual Studio 2022.

To Reproduce

I created a blank windows console app with the following code.

#include <iostream>
#include "signalrclient/hub_connection.h"

int main()
{
    std::cout << "Hello World!\n";

    {
        std::map<std::string, std::string> http_headers;
        http_headers.insert({ "Authorization", "" });

        signalr::signalr_client_config config;
        config.set_http_headers(http_headers);
    }

    std::cout << "finished.\n";
}

These kinds of issues can occur if you use different compilers/compiler versions for different parts of your application.

What compiler did you use via vcpkg to build microsoft-signalr? And what compiler are you using with VS 2022?

Hi Brennan, I'm on windows and using the default compiler in both cases, so that would be the MSVC compiler if I'm not mistaken.
I am using the v143 Platform Toolset in VS 2022 and I created a custom triplet which is a copy of x64-windows but with set(VCPKG_PLATFORM_TOOLSET v143) added.

Ah, the issue is that your application needs to define USE_CPPRESTSDK, that requirement will go away in the future.

Thanks, all looks good now.
