 # Build Instructions
 
 ### Setup
 
-The program was built using Visual Studio 2017. Before opening the solution, please make sure you have the following workloads and components installed (optional components that are not listed can be deselected to save space):
+The program can be built using Visual Studio 2019. Before opening the solution, please make sure you have the following workloads and components installed (optional components that are not listed can be deselected to save space):
 * **.NET desktop development**
-  * .NET Framework 4 – 4.6 development tools
+  * .NET Framework 4.7.2 SDK
   * F# desktop language support
 * **Desktop development with C++**
-  * VC++ 2017 latest v141 tools
+  * MSVC v142 - VS 2019 C++ x64/x86 build tools (v14.20)
 
 After opening the solution, right-click the solution and select **Restore NuGet Packages**, or manually run this command in the **Package Manager Console**:
 ```
-PM> Install-Package CefSharp.WinForms -Version 67.0.0-pre01
+PM> Install-Package CefSharp.WinForms -Version 67.0.0
 ```
 
-Note that some pre-release builds of CefSharp are not available on NuGet. To correctly restore packages in that case, open **Package Manager Settings**, and add `https://www.myget.org/F/cefsharp/api/v3/index.json` to the list of package sources.
-
 ### Debug
 
 The `Debug` configuration uses a separate data folder by default (`%LOCALAPPDATA%\TweetDuckDebug`) to avoid affecting an existing installation of TweetDuck. You can modify this by opening **TweetDuck Properties** in Visual Studio, clicking the **Debug** tab, and changing the **Command line arguments** field.
 
-While debugging, opening the main menu and clicking **Reload browser** automatically rebuilds all resources in `Resources/Scripts` and `Resources/Plugins`. This allows editing HTML/CSS/JS files without restarting the program, but it will cause a short delay between browser reloads. An F# compiler must be present when building the project to enable this feature: `C:\Program Files (x86)\Microsoft SDKs\F#\10.1\Framework\v4.0\fsc.exe`

 ### Installers
 
-TweetDuck uses **Inno Setup** for installers and updates. First, download and install [InnoSetup QuickStart Pack](http://www.jrsoftware.org/isdl.php) (non-unicode; editor and encryption support not required) and the [Inno Download Plugin](https://code.google.com/archive/p/inno-download-plugin).
