Can the C# interactive window interact with my cod

问题:

I installed Roslyn. Now, if I know where to look in Visual Studio, I can open the 'C# interactive window', and run code:

That's cute. Now how can I interact my code—my classes? Assume I have a project open.

When using Visual Studio 2015:

You can open the Interactive window by navigating to Views > Other Windows > C# Interactive,

Then just right click your project and run Initialize Interactive with Project from the context menu.

You can also use the Immediate Window to interact with your code as well, like so:

Just an update from the @Botz3000 answer.

The command you want to find is now called "Initialize Interactive with Project"

Also it is worth noting i could not find this command if my C# interactive window was not viewable.

Don't forget to change class name range, to public class name.

Totally agree "Initializa Interactive with Project" is cool.

My approach is to push classes into a library and use //css_reference in C# script or #r in C# Interactive window

For example:

#r "D:\\dev\\DbHMonData\\LoadH2Stats\\bin\\Debug\\DbHMonStats.dll"
using DbHMonStats;
