What is a NuGet package and how can you publish your .net core project as NuGet Package?

A NuGet package is a collection of code, assets, and other files that can be easily shared and distributed in .NET Core projects. It provides a way to easily manage dependencies and include third-party libraries in your project.

To publish your .NET Core project as a NuGet package, you need to follow these steps:

1. Create a .nuspec file: The .nuspec file is an XML file that contains information about your package, such as its name, version, description, and dependencies. You can create this file manually or use the dotnet pack command to generate it automatically.
2. Build your project: Use the dotnet build command to build your project and generate the necessary artifacts.
3. Create the NuGet package: Use the dotnet pack command to create the NuGet package. This command will generate a .nupkg file that contains your project's code and assets, as well as the .nuspec file.
4. Publish the NuGet package: You can publish the package to a public or private NuGet repository, such as NuGet.org or your own NuGet server. You can use the dotnet nuget push command to publish your package.

After publishing your package, other developers can easily include it in their projects by adding it as a dependency in their project file. They can use the dotnet restore command to download and install the package and its dependencies.
