Create and Publish own nuget package
First create class library project, here I have created "DemoApp" project.
Generate the initial manifest
Open a command prompt and navigate to the project folder containing DemoApp.csproj file.
Run the following command:
nuget spec DemoApp.csproj
By specifying a project, NuGet creates a manifest that matches the name of the project, in this case DemoApp.nuspec. It also include replacement tokens in the manifest.
Open DemoApp.nuspec in a text editor to examine its contents and udpate
Create Package
From a command prompt in the folder containing your .nuspec file, run the command
nuget pack
NuGet generates a .nupkg file in the form of identifier-version.nupkg, which you'll find in the current folder.
Publish with nuget push
nuget push DemoApp.1.0.0.nupkg APIKey-GetFrom-Nuget-Account -Source https://api.nuget.org/v3/index.json
Hope this will help you and save your time.
Enjoy !!!
