Commented Unassigned: Error with cpprest desktop for platform toolset v140 [383]

I am trying to run a basic example for http_listener and I am getting the following runtime error:
> The procedure entry point ?_CallInContext@_ContextCallback@details@Concurrency@@QBEXV?$function@$$A6AXXZ@std@@@Z could not be located in the dynamic link library MSVCP140D.dll.

I am using Visual Studio 2015 RC with the v140 platform toolset, running on windows 7, using the cpprest 2.5.0 v140 sdk from nuget. This is happening on both Debug and Release builds.

I tried using cpprest v120 using the v120 platform toolset in Visual Studio 2015 and that worked.

Here is a minimal repro:
```
#include <cpprest/http_listener.h>

using namespace web::http::experimental::listener;

int main() {
http_listener listener(L"http://localhost:9999");

return 0;
}
```
Comments: Thanks for the info and the quick reply. Will build from source.
