Unable to start program debug

[Mapaler]

Problem encountered on https://dotnet.microsoft.com/zh-cn/learn/maui/first-app-tutorial/run Operating System: windows 10 [10.0.19045.3803]

Following the tutorial, a new program called "Auto Login" was created.

After clicking "Windows Machine", the prompt indicates that need to deploy before debug.

The following message appears in the error list

DEP0700: 应用程序注册失败。[0x80080204] 错误 0xC00CE169: 应用部件清单(manifest)验证错误: 根据架构，应用部件清单必须是有效的: 行: 10，列: 13，原因: 'com.companyname.auto_login' 违反了 '[-.A-Za-z0-9]+' 的 pattern 约束。无法分析值为 'com.companyname.auto_login' 的属性 'Name'。 Auto Login

I tried changing the package name in AndroidManifest.xml. But nothing has changed, and the error is still there.

Hi there. We are going to need more information, preferably in english language. Please provide us the output logs so that we can further help you !

Cheers, TD

1. Create new MAUI APP
   

2. Named "test app"
   

3. Choose .NET 8

4. Run "Windows Machine" I changed my display language and Visual Studio language to English, but the Error inform is also Chinese.

   Error DEP0700: Registration of the app failed. [0x80080204] 错误 0xC00CE169: 应用部件清单(manifest)验证错误: 根据架构，应用部件清单必须是有效的: 行: 10，列: 13，原因: 'com.companyname.test_app' 违反了 '[-.A-Za-z0-9]+' 的 pattern 约束。
   无法分析值为 'com.companyname.test_app' 的属性 'Name'。

   And output is

   Creating a new clean layout... Copying files: Total 38 mb to layout... Checking whether required frameworks are installed... Registering the application to run from layout... DEP0700: Registration of the app failed. [0x80080204] 错误 0xC00CE169: 应用部件清单(manifest)验证错误: 根据架构，应用部件清单必须是有效的: 行: 10，列: 13，原因: 'com.companyname.test_app' 违反了 '[-.A-Za-z0-9]+' 的 pattern 约束。 无法分析值为 'com.companyname.test_app' 的属性 'Name'。

   ========== Build: 1 succeeded, 0 failed, 0 up-to-date, 0 skipped ========== ========== Build completed at 10:17 PM and took 09.977 seconds ========== ========== Deploy: 1 succeeded, 0 failed, 0 skipped ========== ========== Deploy completed at 10:17 PM and took 09.978 seconds ==========

5. I tested both "test_app" and "test-app" also had the same error, only "testapp" worked fine

Right click on the solution -> Configuration Manager -> Enable Deploy on startup project

I't checked.

Translate the error into English. I think the problem is that the special character in the package name is converted to "_", but it is not allowed in the name rules.

Error 0xC00CE169: Application manifest validation error: Depending on the schema, the application manifest must be valid: row: 10, column: 13, reason: 'com.companyname.test_app' violates '[-. A-Za-z0-9]+'. Unable to parse attribute 'Name' with value 'com.companyname.test_app'.

So I tested both "test_app" and "test-app" also had the same error, but "testapp" worked fine.
