Can't install local NuGet package

Question

Details

• Using Visual Studio 2017
• Built NuGet package with NuGet Package Explorer
• Placed .nupkg file in local folder on disk
• Added folder to Package Sources in Visual Studio
• I attempt to install the package using the Visual Studio GUI (Tools > NuGet Package Manager > Manage NuGet Packages for Solution...).

Problem

My package shows up in the list in the GUI, but when I click install, an error message says it can't find the package in the folder I put the .nupkg file in:

Package 'TDDeviceIntegration 1.0.0' is not found in the following primary source(s): 'C:\Users\j.smith\Documents\Visual Studio 2017\LocalNugetRepository\'. Please verify all your online package sources are available (OR) package id, version are specified correctly.   

What I've tried

• Putting the NuGet Package I've built in several different local folder locations and adding those to the Package Sources, all with the same result (it can't find the package I JUST put there).
• I've restarted Visual Studio several times.
• I've restarted my computer.
• I've cleared my NuGet cache(s) from Visual Studio

Question

How do I diagnose this? How do I fix this? I just want to make sure that the NuGet package works locally before I give it to the rest of the team.

Thanks in advance!

Just as @orhtej2 comment, you should:

you rename it to TDDeviceIntegration.1.0.0.nupkg? (dot instead of space between package name and version).

Additional, some info about why dot is really the only allowed package name-version separator.

That because namespace of nuget package follows a pattern similar to namespaces in .NET, using dot notation instead of hyphens.

You can get the source from following document:

Choosing a unique package identifier and setting the version number

Hope this helps.

Answer 2

According to this link from the NuGet GitHub Repository, you can possibly encounter this error when the version of your package is not "normalized", i.e. it's not made up of 4 digits. Yours has 3 digits, so...

(and the last digit might have to be 0).
