Hi tarun k
The error MSB3644 indicates that reference assemblies for .NET Framework 4.6.1 are not available on the build agent. Your script installs the 4.5.2 Targeting Pack, but not 4.6.1.
Add this line in your script after --add Microsoft.Net.Component.4.5.2.TargetingPack `
--add Microsoft.Net.Component.4.6.1.TargetingPack `
Hope this helps!
Please Let me know if you have any queries.

Hi tarun k
For Microsoft-hosted agents, this version is not guaranteed to be available. You’ll need a self-hosted Windows agent to ensure compatibility.
Windows Hosted Agent (windows-latest) no longer has legacy framework targeting packs like 4.5.2. - https://dotnet.microsoft.com/en-us/download/visual-studio-sdks?cid=msbuild-developerpacks
It has been depreciated.

Hope this helps!
