Tutorial CefSharp

Buka Menu: Project -> Manage NuGet Package

Pasang CefSharp.Winform, CefSharp.Common

Ganti Target Net 4.5.2 keatas dan platform configuration (x86, x64 or AnyCPU)

Jika menggunakan AnyCPU, bagian Project > Your Project Properties > Build centang bagian Prefer-32bit. Jika menggunakan x64, buatlah Configurasi untuk x64 (Silahkan googling)

Perbaiki file .csproj

Tambahkan sebelum tag </PropertyGroup>

<CefSharpAnyCpuSupport>true</CefSharpAnyCpuSupport>

Configuration Error

jika menemukan: Please check to make sure that you have specified a valid combination of Configuration and Platform for this project. Maka buka

Klik kanan Project > Properties > Build lalu cut pada bagian Output Path. Selanjutnya Build project lalu paste lagi di tempat semula. Selanjutnya silahkan coba rebuild lagi.
