The new Custom Functoid Class item template for Visual Studio 2015 allows you to create new Functoids for BizTalk Server 2016 without having to code the entire class and therefore allowing you to focus on what really matters, the functoid behavior. Just start a new Visual Studio C# library project and add a functoid class to start building your BizTalk Server 2016 custom Functoid.
To use this item template in your C# library projects just download the project (Don´t unzip) and copy the compressed file to C:\Users\<UserName>\Documents\Visual Studio 2015\Templates\ItemTemplates\Visual C#.
Now when you add a new item to your project you will now see a new option: “Custom FunctoId Class”
This project was made along with my fellow team members.
