.NET Central Package Management: How Can I Enforce Strict Package Version Limits?

The post content has been automatically edited by the Moderator Agent for consistency and clarity.

I am fairly new to professional development and have recently started a new job.
I need to enforce a strict package version limit due to licensing changes, so that no developer can install (or even attempt to install) a package version above a certain threshold.

So far, all the information I’ve found seems outdated and ineffective in my scenario. For example, I tried configuring the allowed versions between 6 and 7.x.x using central package management as follows:

XML
<PackageVersion Include="PackageName" Version="[6, 8)" />

However, this configuration only affects the update button by picking the highest allowed version. Developers can still manually override this by specifying a version like:

XML
<PackageVersion Include="PackageName" Version="9.1" />

This completely bypasses any version limiting defined in the Directory.Packages.props file. Unlike the old packages.config system that had an AllowedVersions metadata to disable out-of-range versions in the NuGet installer, the modern PackageReference/central package management system appears to only use version ranges for dependency resolution, not enforcement.

Is there a way to actually enforce strict package version limits using the current central package management system, rather than merely influencing update suggestions?

Below is a summary of the current situation with package version limiting using central package management in modern .NET projects:

Version ranges in Directory.Packages.props are advisory.
The range you specify (for example, Version="[6, 8)") tells the dependency resolution process which versions to select when automatically updating packages. However, it does not prevent someone from manually changing the version in their project file. If a developer overrides the central version by specifying, for example, Version="9.1", then that version will be used.
Modern PackageReference/Central Package Management vs. packages.config.
The old packages.config system supported an AllowedVersions metadata that disabled selection of out-of-range versions in the NuGet UI. Unfortunately, there is no direct equivalent in the modern PackageReference (and by extension, central package management) system. In these systems, version ranges influence dependency resolution rather than enforce a strict available set of versions that the NuGet UI will disallow.
Enforcement options.
Currently there’s no built-in feature to prevent manual overrides or enforce strict version limits at install time. If this behavior is critical for your team (for example, due to licensing restrictions), you may have to:
- Educate your team on the importance of not overriding the defined version range.
- Implement a build-time policy check (for example, via a custom MSBuild task or analyzer) to fail the build when an out-of-range version is used.
- Use package management solutions on your package repository (e.g., a NuGet server) that can enforce version policies.

Unfortunately, as of now the central package management system does not offer the same level of enforcement as the old packages.config AllowedVersions feature. You might consider raising this as feedback on the NuGet GitHub repo so that future releases could include a more robust mechanism to lock package versions.

Hope this helps clarify the current capabilities and limitations.

There is lots of options to do this, here are some

Track the version or how many times it's been used from from software data AppData\Local\MySoftware\Version.txt, AppData\Local\MySoftware\Used.txt
You can add the version in the code then track it on the website or server side
The most secure way make a login for the software then make a encryption hash to make sure they are logged in from their ip address, password, time, etc
then you can add the encrypted code on the website or server side to stop decompiling
you can also control versions and installs, etc with the login unless they are capturing the packets and decrypting them to see the code

Here is an example of 2

php code

PHP
<?php
// Sanitize and validate the 'version' parameter
$version = filter_input(INPUT_GET, 'version', FILTER_SANITIZE_STRING);

// Check if version is provided and valid
if ($version && version_compare($version, '2.0.0.0', '<')) {
    echo "Yes";
} else {
    echo "Invalid version or no update needed.";
}
?>

.net code

VBNET
Imports System.Net

Public Class Form1
    Private Async Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
        Dim client As New WebClient()
        Dim version As String = "1.0.0.0"
        Dim versionDataUrl As String = "http://www.mywebsite.com/update.php?version=" & version

        Try
            ' Asynchronously fetch version data
            Dim versionData As String = Await client.DownloadStringTaskAsync(versionDataUrl)

            If versionData = "Yes" Then
                MessageBox.Show("Sorry, an update is needed!")
                Application.Exit()
            End If

        Catch ex As WebException
            MessageBox.Show("Network error occurred: " & ex.Message)
        Catch ex As Exception
            MessageBox.Show("An error occurred: " & ex.Message)
        Finally
            client.Dispose()
        End Try
    End Sub
End Class
