In a project we have Umbraco 7.3.4 and it has a dependency for JSON.NET <= 6.0.8. When I'm trying to install other 3rd party packages which require JSON.NET >= 8.0.0, this forces Umbraco to automatically update to version 7.4, which I don't want.
Putting aside considerations of pros and cons of making a hack, I am happy to do a hack because I know that Umbraco works with JSON.NET 8.0.0. The question is how to disable in Nuget automatic update (dependency resolving) only for the Umbraco package? In an ideal case (and much better one) I would only want to ignore JSON.NET dependency for Umbraco package, but let Nuget update Umbraco package if any other cross-dependency update requires this.
Many thanks for an advice
This isn't an Umbraco feature but a Nuget feature, you can include the flag -IgnoreDependencies but it's not selective as far as I am aware. Beware you may well miss other dependencies that could cause you to end up in dependency hell!
Example:
Update-Package Newtonsoft.Json -Version 8.0.0 -IgnoreDependencies
Nuget Documentation:
-IgnoreDependencies
Installs only this package and not its dependencies.
Required: false
See https://docs.nuget.org/consume/package-manager-console-powershell-reference
Warning: Backup your project before attempting this so you can roll it back in the event of a problem!

According to a recent JFrog Xray scan, our application (.NET 5) has a "critical" vulnerability due to a dependency on a specific version of Microsoft.NETCore.Platforms. There is a newer version of the package with the vulnerability resolved that I want my project to use instead. The problem I'm having is that this is not a package that we've explicitly added to the project, but rather a dependency that some other packages have, so simply adding the newer version of the package to the project isn't enough to remove the dependency entirely; I can still see references to the "bad" version appearing in project.assets.json. Upgrading to the latest version of the top-level packages has helped, but has still left some references to the "bad" version of Microsoft.NETCore.Platforms via dependencies of dependencies of dependencies.
E.g, we're using the very latest version of Microsoft.ApplicationInsights, but this has a dependency on System.Diagnostics.PerformanceCounter, which has a dependency on the "bad" Microsoft.NETCore.Platforms.
TLDR; I want to be able to tell my project "If you have a dependency on this package anywhere in your dependency tree, don't use version X, use version Y instead", but I'm not sure if there exists a way to do this.
You can't change what version of a library your dependencies use because that could easily introduce breaking changes. This is the modern version of DLL hell.
The answer is to update the library that has the old dependency. If it's open source, you can do this yourself and use your forked version with the updated dependencies. If you don't have access to the source then you will have to contact the developer and tell them about the vulnerability.
If the developer is Microsoft, godspeed.
I have a private NuGet package that I'm installing on an existing project. The project already contains several of the dependencies the private NuGet package requires but at a lower version than what the private package requires. When I try to install the private package the installation throws an error (no error number)
Package restore failed. Rolling back package changes for
'ConsoleApp1'.
In the package manager output it is reporting a
Detected package downgrade
Since the package that it's referencing is a public package on NuGet.org I would expect at a minimum to be prompted to upgrade the dependency during the installation process instead of erroring and rolling back. I've know packages that are not already included in the project are being installed automatically and can see that in the logs.
I've seen other posting that range from ignoring the warning/error to a pre-build script that does the upgrade (which is not a option for installing new packages)
Can the package manager be instructed to automatically upgrade the existing packages to at least the minimum version the dependency list has defined?
Afraid not.
It's not really a trivial problem to solve - suppose it uses the approach you suggested and your project currently references packageA v1.0.0 and packageB v1.0.0.
You add a new package with a dependency on package A v2.0.0.
It prompts you to upgrade packageAfrom 1.0.0 to 2.0.0 to avoid a downgrade.
But package A 2.0.0 has a new dependency on packageBat 2.0.0, which causes a downgrade for you on that package.
Every new upgrade in turn can trigger new upgrades. You can also engineer scenarios where there isn't even a way to upgrade other packages to make it all work. On top of that all of this requires fetching lots of information from your package source.
Since there's not a clear, general way to fix this the tooling leaves you to work out what you want to do yourself.
I am working on VS2012 and have issue with installing Twilio Package via NuGet. It asks me to update NuGet Package Manager. I am concerned if updating NuGet Package Manager have effect on all the projects that are running without any issue. What are the effects of Package Manager Updates on existing projects or solution.
Coming from the Python world, I will attempt to see if I can help you here. Is the concern that a specific package will no longer be available to you if you do a global update on your NuGet package manager?
Is it possible then for you to install a specific NuGet version in a virtual machine encapsulating the project where you want to run with the Twilio package?
Otherwise, assuming all of the packages you use are regularly maintained, I'm not sure how an update to a package manager would affect them.
I'm looking for some experience or thoughts on the following problem.
I have a Nuget Package (EntityFrameworkExtras 1.2.0) thats hosted on the main Nuget Feed.
This package has a dependency on EntityFramework. Everything was hunky dorey until EntityFramework 6 was released.
A change in the EntityFramework code means that my package no longer works with EntityFramework 6 and onwards.
I'm trying to consider how best to deal with this problem, i foresee two options:
1) Maintain 2 versions of the Package
So, i would have one version of the package that is compiled with EntityFramework 5.0.0 and the .nuspec would
dictate that it is dependant on EntityFramework [0.0.0 - 5.0.0]
I would introduce a new package called EntityFrameworkExtras (ef6). This package would be compiled in EntityFramework 6.0.0
and the .nuspec would dictate that it is dependant on EntityFramework [6.0.0 >= *]
2) Have a new version of the current package that would support EntityFramework 6.0
so the currently version would support EntityFramework 5.0.0 and less
and i would add a new version of the package (version 2.0.0) that would depend on EntityFramework 6.0.0 [6.0.0 >= *]
I went for option 1) in the end. I believe this is an easier option for the user of the packages because its clear what each of the package's dependencies are.
I also believe its easier to use the nuget commands when working with different packages, rather then attempting to be aware that different versions of one package have different dependency versions.
Also from a development perspective it cleaner and easier to develop and fix bugs on the different packages. Finally, it would make a continuous integration environment easier to implement, because each package would be consider a different project.
I want to make my .net 4 project load the .net 3.5 version of a nuget package so that other .net 3.5 references don't get the nuget dll overwritten in the output directory.
Yikes! If the package has a .NET 3.5 and a .NET 4 version of the DLL, there's no real way to do that other than changing your project to target 3.5 itself.
I can think of a couple of workarounds though. They're not ideal, but they'd probably work.
After you install the nuget package, go into the "packages" directory (it'll be next to your solution (.sln) file. Find the package. Delete the "\lib\net40" folder. This way, NuGet will reference the next version down. You'll have to manually change the assembly reference. Note if you even upgrade this package, you'll have to do this again.
You could create a custom version of this package that only contains your 3.5 version of the DLL. Perhaps put this up in a custom feed at http://myget.org/ and install it from there.
One of those ought to work.
