Creating a NuGet package for my .NET Standard class library

I successfully created and published my first NuGet package that included a .NET Standard class library here.  It is nothing specifically awesome but it’s pretty cool, simple and something I have never done before.  I simply executed this msbuild command on my .NET Standard class library and it built the package for me.

msbuild CSharpProjectName.csproj /t:pack /p:Configuration=Release

Before I came to the above command conclusion I found another example like this:

dotnet pack --no-build

Not really knowing what that did, I got the below exception when running the command.

The exception was pretty clear that it could not find the DEBUG version of my project, that was because I never compiled a DEBUG version, I went straight to RELEASE without passing GO!  I must assume by not using the p: parameter it defaults to DEBUG.  Not sure still what the –no-build parameter does, I need to read the manual I guess.
