The Net10 Maui Blazor Hybrid project cannot be packaged

[liangfangyin2]

Is there an existing issue for this?

• I have searched the existing issues

Describe the bug

### 描述
The Net Maui Blazor Hybrid project cannot be packaged
The project I developed using VS2026 is based on the Net10 framework. When I try to package it using the command line, I get an error prompt
Command line:
dotnet publish -c Release -f net10.0-windows10.0.19041.0 -r win-x64

Error returned:

E:\tower-stone-configuration-tool\web\Tool\Tool\Tool.csproj : error NU1102:
I cannot find the package Microsoft.NETCore.App.Runtime.Mono.win-x64 with version (= 10.0.1)

• Found 113 versions on nuget.org [Nearest version: 9.0.0-preview.7.24405.7]
• No versions found in Microsoft Visual Studio Offline Packages
• No versions found in C:\Program Files\dotnet\library-packs

I encountered the same error when switching to the Net9 framework later. Finally, I switched to Net8, but unfortunately, VS 2026 cannot run the Maui Blazor Hybrid project for Net8 now
How to solve this problem is extremely urgent

I hope to release version 10.0.1 of Microsoft.NETCore.App.Runtime.Mono.win-x64 or find other solutions

I will first provide you with the solution for the project, which is Tool.csproj

The implementation steps are as follows:
First, enter the Blazor file Tool

Then run cmd under this directory:

The general steps are like this. When I used Net8 a long time ago, I also packed it this way. Back then, it was possible to pack

Steps To Reproduce

You can create a Net Maui Blazor Hybrid project using Vs2026 and then run "dotnet publish -c Release -f net10.0-windows10.0.19041.0 -r win-x64" in the project directory to package. The probability of this issue occurring is 100%. I hope you can resolve it as soon as possible, as it has seriously affected my usage

Exceptions (if any)

No response

.NET Version

dotnet publish -c Release -f net10.0-windows10.0.19041.0 -r win-x64

Anything else?

Vs2026
Create .Net Maui Blazor Hybrid and select .Net 10
项目目录运行：dotnet publish -c Release -f net10.0-windows10.0.19041.0 -r win-x64
