NuGet 4.0 RTM Release Notes

  • Article

Visual Studio 2017 comes with NuGet 4.0 which adds support for .NET Core, has a bunch of quality fixes and improves performance. This release also brings several improvements like support for PackageReference, NuGet commands as MSBuild targets, background package restores, and more.

Known issues

NuGet restore may fail when you have multiple projects referencing another project in a solution

Issue

NuGet restore may not work if, in a solution, you have project references to the same project with different casing or with different relative paths. NuGet#4574

Workaround

Fix the casings or relative paths to be the same for all project references.

While using Package Manager Console, 'Enter' key may not work

Issue

Occasionally, the enter key does not work in the Package Manager Console. If you see this, please check out the progress on the fix, and provide any additional helpful information about your repro steps. NuGet#4204 NuGet#4570

Workaround

Restart Visual Studio and open the PMC before opening the solution. Alternatively, try deleting the project.lock.json and restoring again.

In .NET Core projects, you may end up in infinite restore loop when you use a package containing an assembly with an invalid signature

Issue

Occassionally, when you use a package containing an assembly with an invalid signature or when the package version is set with 'DateTime' ticker, it causes package auto-restore to run in infinite loop. NuGet#4542

Workaround

There is no workaround at this time.

You are unable to view, add, or update DotNetCLITools, using Nuget Package Manager

Issue

NuGet Package Manager does not display and does not allow add/update of DotNetCLITools. NuGet#4256

Workaround

DotNetCLIToolReferences must be manually edited in your project file.

NuGet restore will fail when you set PackageId property for projects

Issue

For .NET Core projects, NuGet restore in Visual Studio does not respect PackageId property of projects. NuGet#4586

Workaround

Run restore using the command-line.

When your project does not have 'obj' folder, package restore may fail

Issue

Visual Studio fails to restore PackageReferences when 'obj' folder has been deleted. NuGet#4528

Workaround

Create 'obj' folder manually and the restore should work.

Manually updating packages using Update-Package in console may fail

Issue

Using Update-Package manually in the console only works once for PackageReferences projects that were just converted. NuGet#4431

Workaround

There is no workaround at this time.

Retargeting target framework version may lead to incomplete Intellisense

Issue

Retargeting target framework version may lead to incomplete Intellisense, in Visual Studio. This happens when you are using PackageReferences as the package manager format. NuGet#4216

Workaround

Do a manual restore.

msbuild /t:restore fails when a project targeting .NET461 references another project targeting .NETStandard

Issue

msbuild /t:restore fails when a PackageReferenece based project targeting .NET461 references another PackageReference based project targeting .NETStandard. NuGet#4532

Workaround

There is no workaround at this time.
