VS: solution user options fail to deserialize after NuGet update

[dtivel]

Repro steps:

1. Install Visual Studio 2019. (This should also work with older versions (2017, 2015, …).)
2. Launch Visual Studio.
3. Create a C# class library project (.NET Framework).
4. In the Solution Explorer tool window, right-click on the project and select "Manage NuGet Packages..."
5. Exit Visual Studio.
6. Install a newer NuGet VSIX.
   (Optional) Open a developer command prompt and run: devenv /clearCache
7. Launch Visual Studio.
8. Open the project created in step 3.
9. In the Solution Explorer tool window, right-click on the project and select "Manage NuGet Packages..."

Result:
A System.Runtime.Serialization.SerializationException exception is thrown here.

System.Runtime.Serialization.SerializationException: Unable to find assembly 'NuGet.Tools, Version=5.2.0.1108, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'.

NuGet serializes its solution user options using binary serialization and this creates a dependency on the exact assembly (per strong name) used to serialize those settings.

For example, here is a snapshot of the types required to successfully deserialize NuGet solution user options on a particular NuGet build.

• NuGetVSExtension.NuGetSettings, NuGet.Tools, Version=5.2.0.524, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a
• System.Collections.Generic.Dictionary``2[[System.String, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089],[NuGet.PackageManagement.UI.UserSettings, * NuGet.PackageManagement.UI, Version=5.2.0.524, Culture=neutral, PublicKeyToken=31bf3856ad364e35]], mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089
• System.OrdinalComparer, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089
• System.Collections.Generic.KeyValuePair``2[[System.String, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089],[NuGet.PackageManagement.UI.UserSettings, NuGet.PackageManagement.UI, Version=5.2.0.524, Culture=neutral, PublicKeyToken=31bf3856ad364e35]], mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089
• NuGet.PackageManagement.UI.UserSettings, NuGet.PackageManagement.UI, Version=5.2.0.524, Culture=neutral, PublicKeyToken=31bf3856ad364e35
• NuGet.PackageManagement.UI.ItemFilter, NuGet.PackageManagement.UI, Version=5.2.0.524, Culture=neutral, PublicKeyToken=31bf3856ad364e35
• NuGet.Resolver.DependencyBehavior, NuGet.Resolver, Version=5.2.0.2, Culture=neutral, PublicKeyToken=31bf3856ad364e35
• NuGet.ProjectManagement.FileConflictAction, NuGet.PackageManagement, Version=5.2.0.2, Culture=neutral, PublicKeyToken=31bf3856ad364e35
• System.ComponentModel.ListSortDirection, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089

If these exact NuGet assemblies aren't available, deserialization will fail.
