ResolveAssemblyReferences logs information about what references were involved in the leadup to a conflict

  There was a conflict between "StreamJsonRpc, Version=2.1.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" and "StreamJsonRpc, Version=2.2.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a". (TaskId:25)

C:\Program Files (x86)\Microsoft Visual Studio\2019\Preview\MSBuild\Current\Bin\Microsoft.Common.CurrentVersion.targets(2106,5): warning MSB3277: Found conflicts between different versions of "StreamJsonRpc" that could not be resolved.  These reference conflicts are listed in the build log when log verbosity is set to detailed. [S:\project-system\src\Microsoft.VisualStudio.ProjectSystem.Managed.VS\Microsoft.VisualStudio.ProjectSystem.Managed.VS.csproj]

But that logging is unclear, because most of those assemblies didn't have a reference to version 2.2.0.0 of StreamJsonRpc:

$ ildasm /text C:\Users\raines\.nuget\packages\microsoft.servicehub.framework\2.0.72\lib\netstandard2.0\Microsoft.ServiceHub.Framework.dll | rg -A4 "assembly extern StreamJsonRpc"                                                             .assembly extern StreamJsonRpc
{
  .publickeytoken = (B0 3F 5F 7F 11 D5 0A 3A )                         // .?_....:
  .ver 2:1:0:0
}
$ ildasm /text C:\Users\raines\.nuget\packages\microsoft.visualstudio.language\16.0.428\lib\net472\Microsoft.VisualStudio.Language.dll | rg -A4 "assembly extern StreamJsonRpc"                                                                 .assembly extern StreamJsonRpc
{
  .publickeytoken = (B0 3F 5F 7F 11 D5 0A 3A )                         // .?_....:
  .ver 1:3:0:0
}
$ ildasm /text C:\Users\raines\.nuget\packages\microsoft.visualstudio.languageservices\3.2.0-beta4-19359-03\lib\net472\Microsoft.VisualStudio.LanguageServices.dll | rg -A4 "assembly extern StreamJsonRpc"                                     .assembly extern StreamJsonRpc
{
  .publickeytoken = (B0 3F 5F 7F 11 D5 0A 3A )                         // .?_....:
  .ver 2:0:0:0
}
$ ildasm /text C:\Users\raines\.nuget\packages\microsoft.visualstudio.utilities\16.4.29317.144\lib\net46\Microsoft.VisualStudio.Utilities.dll | rg -A4 "assembly extern StreamJsonRpc"                                                          .assembly extern StreamJsonRpc
{
  .publickeytoken = (B0 3F 5F 7F 11 D5 0A 3A )                         // .?_....:
  .ver 2:2:0:0
}            

Instead, they had references that RAR considered unifiable to the 2.2.0.0 version.

To really debug this problem, it would be nice to see the actual versions referenced, plus whether they were unifiable or not. In this case the error is that the direct reference is less than the highest indirect reference. Maybe we could just . . . say that?

Spamming a few keywords in here:

• reference can be unified to a higher version
• one of the dlls it lists wants the higher version, but the log messages don't say which one it is
• MSB3277
