Repro Steps & Context

NU1102's error message refers to the requested, not the resolved version. This can be extremely misleading, because it can create logs like this:

error NU1102: Unable to find package MyPackage with version (>= 10.8.0.113526)
error NU1102:   - Found 29 version(s) in MySource [ Nearest version: 10.8.0.113526 ]

The problem here is that my csproj-file was requesting version 10.8.0.113526 but the packages.lock.json file was pinning it to 10.8.0.111573 (which is higher and thus eligible) but only 10.8.0.113526 was present in the package source. The error message was completely hiding the fact and send me on a multi-hour bug hunt.

I would expect to see a log similar to this instead:

error NU1102: Unable to find package MyPackage with version 10.8.0.111573
error NU1102:   - Found 29 version(s) in MySource [ Nearest version: 10.8.0.113526 ]

This would make the problem obvious and point me in the right direction.

Even better would be to mention both versions. Maybe like this:

error NU1102: Unable to find package MyPackage with version 10.8.0.111573 (requested version: 10.8.0.113526)
error NU1102:   - Found 29 version(s) in MySource [ Nearest version: 10.8.0.113526 ]

Here's a sample to repro the issue: gh14279.zip

I have the project reference Newtonsoft.Json 13.0.0, because that version doesn't exist and would normally upgrade to 13.0.1 with a warning. But I hand edited the lock file to use 14.0.1, which doesn't exist, but we get this error message:

    D:\src\test\gh14279\gh14279.csproj : error NU1102:
      Unable to find package Newtonsoft.Json with version (>= 13.0.0)
        - Found 81 version(s) in nuget.org [ Nearest version: 13.0.1-beta1 ]
        - Found 1 version(s) in Microsoft Visual Studio Offline Packages [ Nearest version: 13.0.1 ]
        - Found 0 version(s) in C:\Program Files\dotnet\library-packs

Restore failed with 1 error(s) in 0.8s

indeed, no message mentioning 14.0.1 as the version actually being searched for.
