Compile issues

[Stateford]

When trying to compile I get an error. I copied and pasted the code from a previous project I have done and it doesn't work in a new project. I downloaded the latest from nuget, as well as used the casablanca files from my previous project.

It compiles just fine in my previous project, but not in the new one. Not really sure what is causing this, but I don't think I'm the only one having this issue.

All the errors point to cpprestsdk files.

Did you change the version of your compiler, without updating version of cpprestsdk perhaps?

For example, your first error is fixed by commit 31b0e47, for v2.10.0. Your second error, C7510 regarding 'int_type', is fixed by commit 05e474a, for v2.10.1.

I was using 2.9.1.1, I was going off the latest on nuget.

I'll download the latest and include it, but it's strange that it is working fine in another project.

I was using Visual Studio 2017 (which has a separate issue, see #523), and ran into this issue. I was also using the latest version posted in nuget, which does not include the fixes that garethsb-sony had mentioned above. I fixed this by using
vcpkg install cpprestsdk cpprestsdk:x64-windows instead (see readme).

I had also reproduced this using v140.
I suppose the real issue here is nuget providing an old release.

[Stateford]

There's no plans to update nuget. Check issue #672 for more information. Better to use VCPKG and point include directories to it
