How to Resolve Package Restore Failure while Migrating ASP.NET Core?
The Syncfusion® ASP.NET Core application will get the following error message while migrating the Syncfusion® ASP.NET Core application from Syncfusion® Migration Visual Studio Extension.
When updating NuGet packages in your application, the process may fail if the required version is not available in the local NuGet cache. This issue can also occur when using the Syncfusion® Project Migration utility to switch to a different version, especially if the Syncfusion® ASP.NET Core NuGet packages used in the project are missing from the cache.
To avoid this issue, make sure to configure the online Syncfusion® NuGet feed in Visual Studio before migrating your Syncfusion® ASP.NET Core application.
This ensures that the required Syncfusion® NuGet packages (used in the project before migration) can be downloaded if they are not available in the local NuGet cache.
Perform the steps from the below user guide to configure the Syncfusion® ASP.NET Core NuGet feed in your Visual Studio.

Note:
Make sure whether default nuget.org NuGet source has been configured in NuGet Package Manager.
