Azure devops gives NuGet package restore error for reference project

Question

NuGet package restore error for the solution which have a mix of .netcoreapp3.1 and .NETStandard 2.1 projects.

I have multiple .net projects in one solution file which are added as references to each other projects. Some of the projects has .netcore 3.1 version and some of has .NET Standard 2.1. It is working fine in my local machine.

Now i am creating my azure devops build pipeline using classic editor and selected the asp.net core template so it will add all the necessary tasks (Showing in attached image). But it is giving me error in NuGet package restore task "##[error]The nuget command failed with exit code(1) and error(NU1201: Project XX is not compatible with.netcoreapp3.1 (.NETCoreApp,Version=v3.1). Project XX supports:.netstandard2.1 (.NETStandard,Version=v2.1)".

Note: I can not change the any project version as it is used in many other projects, can any one help me on this if i missed anything.

Or you could use the do.net restore task instead of nuget restore:
