New Post: Creating a static library for Casablanca C++ rest SDK 2.3

I am trying to create a static library for my C++ rest SDK project.I have installed Casablanca C++ rest SDK 2.3 using Nuget package. My OS is Winodws8 and I am using VS2012.I have added the cpprest110d_2_3.lib into "Project Property --> Linker --> Input -->Additional Dependencies" and the includes in the Additional Include Directories .

Howerver I am getting the following link errors

error LNK2001: unresolved external symbol "public: static class std::basic_string<wchar_t,struct std::char_traits<wchar_t>,class std::allocator<wchar_t> > const web::http::methods::GET" (?GET@methods@http@web@@2V?$basic_string@_WU?$char_traits@_W@std@@V?$allocator@_W@2@@std@@B)

error LNK2001: unresolved external symbol "public: static class std::basic_string<wchar_t,struct std::char_traits<wchar_t>,class std::allocator<wchar_t> > const web::http::methods::DEL" (?DEL@methods@http@web@@2V?$basic_string@_WU?$char_traits@_W@std@@V?$allocator@_W@2@@std@@B)

I have also tried replacing the lib file with cpprest110d_app_2_3.lib file but I am getting the same errors.

I have directly used the lib files available from the packages that I downloaded from Nuget package.

Please help me in resolving this issue and also time is running out for my project
