| # TDLib C# example | ||
|
|
||
| This is an example of building TDLib with `C++/CLI` support and an example of TDLib usage from C#. | ||
|
|
||
| ## Building TDLib | ||
|
|
||
| * Download and install Microsoft Visual Studio 2015 or later. | ||
| * Download and install [CMake](https://cmake.org/download/). | ||
| * Install [vcpkg](https://github.com/Microsoft/vcpkg#quick-start) or update it to the latest version using `vcpkg update` and following received instructions. | ||
| * Install `zlib` and `openssl` for using `vcpkg`: | ||
| ``` | ||
| C:\src\vcpkg> .\vcpkg.exe install openssl:x64-windows openssl:x86-windows zlib:x64-windows zlib:x86-windows | ||
| ``` | ||
| * Download and install [gperf](https://sourceforge.net/projects/gnuwin32/files/gperf/3.0.1/). Add the path to gperf.exe to the PATH environment variable. | ||
| * Build `TDLib` with CMake enabling .NET support and specifying correct path to `vcpkg` toolchain file: | ||
| ``` | ||
| cd <path to TDLib sources>/example/csharp | ||
| mkdir build | ||
| cd build | ||
| cmake -DTD_ENABLE_DOTNET=ON -DCMAKE_TOOLCHAIN_FILE=C:\src\vcpkg\scripts\buildsystems\vcpkg.cmake ../../.. | ||
| cmake --build . --config Release | ||
| cmake --build . --config Debug | ||
| ``` | ||
|
|
||
| ## Example of usage | ||
|
|
||
| After `TDLib` is built you can open and run TdExample project. | ||
| It contains a simple console C# application with implementation of authorization and message sending. | ||
| Just open it with Visual Studio 2015 or 2017 and run. |
