Creating your first Orleans application

It is time for us to create our first Orleans application. In this section, we are going to build a simple hotel grain, which will greet a guest. A typical Orleans solution structure contains a host application (it could be a console application, a web application, or a native application) that has the Orleans runtime and hosts grain activations, grain interfaces, and grain implementations.

Step 1: Create solution:

1. Create a new solution using the template Blank Solution in Visual Studio and name it Distel.

Step 2: Define grain interfaces: Grain interfaces define the different types of grains involved and their behavior:

1. Add a new project to this solution using the project template Class Library, name it Distel.Grains.Interfaces, and select the target framework .NET6.
2. To this project, add the following NuGet references:
