Create, edit and run multiple C# 9.0 top-level programs in the same project by just selecting the startup one right from the start button!
The new C# 9 top-level programs allow a very intuitive, simple and streamlined experience for quickly spiking or learning C#.
As of Visual Studio 16.8 Preview, you need to turn on this feature by adding this property to your project file:
<LangVersion>Preview</LangVersion>One missing thing in its current incarnation in Visual Studio 16.8 is that you can only have one such top-level programs in a project. This means that in order to prototype or learn a different area of .NET, you'd be forced to either replace your previous top-level program or change it to be a non-compile item somehow so you can keep it around (i.e. rename to a .txt).
SmallSharp brings that very feature by automatically generating a launch profile for each .cs file at the project level:
This list is automatically kept in sync as you add more .cs files to the project. When you select one target C# file, that becomes the only top-level program to be compiled, so you don't have to modify any of the others since they automatically become None items.
All compile files directly under the project directory root are considered top-level programs for selection and compilation purposes. If you need to share code among them, you can place them in subdirectories and those will behave like normal compile items.
