Warning on dotnet core 2.1.0 API project

New to dotnet

VS2017 version: 15.8

.Net core SDK: 2.1.403

My project is showing following Exception:

C:\gitprojects\crm-api\DA Digital APIs\DA.Digital.CRM.Api\DA.Digital.CRM.Api.csproj : warning NU1701: Package 'Microsoft.AspNet.Cors 5.2.6' was restored using '.NETFramework,Version=v4.6.1' instead of the project target framework '.NETCoreApp,Version=v2.1'.

Q: What could be the reason? Is there any solution?

You're using the full framework nuget packages. Use the AspNetCore packages instead.

Let's look at the first warning:

C:\gitprojects\crm-api\DA Digital APIs\DA.Digital.CRM.Api\DA.Digital.CRM.Api.csproj : warning NU1701: Package 'Microsoft.AspNet.Cors 5.2.6' was restored using '.NETFramework,Version=v4.6.1' instead of the project target framework '.NETCoreApp,Version=v2.1'. This package may not be fully compatible with your project.

It's complaining about Microsoft.AspNet.Cors - nuget link.
Use Microsoft.AspNetCore.Cors instead - nuget link.

In general you want to use packages that's fully compatible with what you're targeting. In this case, netstandard2.0 or netcoreapp2.1. (You may check dependencies in nuget.org to verify that.)

For a quickfix, have you tried using Microsoft.AspNetCore.App? nuget link
If not I'd recommend adding that and getting rid of the ASP.NET packages it's complaining about. That'll fix your problem.
