How do I fix the Microsoft.Maui.Resizetizer.dll file not found error when building Maui sample source code?

[nguyentanloi-at]

I built the sample source code at Maui Repository - Essentials and get the error message:

<path>/maui/.nuspec/Microsoft.Maui.Resizetizer.targets(457,9): error MSB4062: The "Microsoft.Maui.Resizetizer.DetectInvalidResourceOutputFilenamesTask" task could not be loaded from the assembly <path>/maui/.nuspec/Microsoft.Maui.Resizetizer.dll. Could not load file or assembly '<path>/maui/.nuspec/Microsoft.Maui.Resizetizer.dll'. The system cannot find the file specified. [<path>/maui/src/Essentials/samples/Samples/Essentials.Sample.csproj] <path>/maui/.nuspec/Microsoft.Maui.Resizetizer.targets(457,9): error MSB4062: Confirm that the declaration is correct, that the assembly and all its dependencies are available, and that the task contains a public class that implements Microsoft.Build.Framework.ITask. [<path>/maui/src/Essentials/samples/Samples/Essentials.Sample.csproj]

NOTE: <path> is the local folder that contain the sample source code.

I installed Microsoft.Maui.Resizetizer.Sdk via .NET CLI command:

dotnet add package Microsoft.Maui.Resizetizer.Sdk --version 6.0.101-preview.10.2068

Rebuilt and I get same errors. Can someone tell me where the problem lies?
