I was able to get this working locally by adding this to my csproj

<UseRidGraph>true</UseRidGraph>
<RuntimeIdentifiers>win10-x86;win10-x64;win10-arm64</RuntimeIdentifiers>

[pratikone]

Thahks for this. @licon4812 is correct. I am planning to use <UseRidGraph>true</UseRidGraph> for maximum backward compatibility for the next release. You can close this PR or change to use Rid

[tonymet]

can you clarify? has it been fixed?

[pratikone]

not yet. I am suggesting to use <UseRidGraph>true</UseRidGraph> in your PR instead of win-x64 values so that it is backward compatible and then lets merge it UseRidGraph>true</UseRidGraph> <RuntimeIdentifiers>win10-x86;win10-x64;win10-arm64</RuntimeIdentifiers>
