Requirement is to create a Core service application on the .Net Core 3.1 framework for Web 8.5 version. Tried the below steps as suggested in the blog. [Blog](https://tridion.stackexchange.com/questions/20415/tridion-contentmanager-coreservice-client-with-net-core) 1. Add new Connected Services 2. Select Microsoft WCF Web Service Reference Provider. 3. Update the core service link https://tridionCmsServer/webservices/CoreService201603.svc 4. Selected the below displayed "CoreService201603" and updated the namespace 5. Selected Reuse types in referenced assemblies 6. Access level for generated classes: -> Public 7. Finish Window with status as Adding connected service to project is displayed. Then below errors are displayed. Failed: See window for error details. It was not possible to find any compatible framework version - The following 'Microsoft.NetCore.App', version "2.1.0" was not found. You can resolve the problem by installing the specified framework and/or SDK. 3.1.1 at [C:\Program Files\dotnet\shared\Microsoft.NETCore.App] The specified framework can be foundat: Done. Do we have any workaround to connect the core service for .NetCore 3.1 or solution to fix this issue. Please let me know, since this is a blocker for us to migrate our whole application to this new framework.
