Yonglun Liu (Shanghai Wicresoft Co,.Ltd.) 50,126 Reputation points Microsoft External Staff2023-01-16T05:12:18.0166667+00:00 Does this issue occur in newly created projects?
If not, you could delete the
obj/andbin/folders of your project, restart your VS and rebuild this project.If so, this should be caused by some error during VS installation, please try reinstalling VS.
Would it be helpful for you?
Your prompt reply will be highly appreciated.

2023-01-16T08:47:49.42+00:00 @yonglun li thanks for your response, this is from a newly created project, and i have even formatted my system and did a completely new installation of VS 2022, the same issue persist. i downloade .net sdk manually and install , yet the same issue persist.
all my students too had the same issue, some just install VS 2022 for the first time and the same error were encounterd by all for newly created MAUi projects
I think the issue is with the latest update 17.4.4, before now 17.4.3 had been running MAUi apps without any issues, even 17.4.4 is very slow comoare to orevious release

For the VS issue, it is more recommended to post it on Developer Community to make our VS team aware of it.

Stewart Basterash 81 Reputation points2024-03-30T00:27:49.0166667+00:00 This is not new behavior to me. It seems that with every update i have these kinds of problems. I recently begain working with MAUI again in hopes of a more stable environment, and it only appears to have gotten worse. With every release, many times, In order to fix this problem, I need to create a new project, move all the project assets (models, viewmodels, services, and custom controls all of which have distinct namespaces just for this purpose). Then I have to recreate all the views from scratch, in order to make things work again. But... this is not the end of the issues. In VS 2022, I need to be extremely careful of typos within source files... one inadvertant keystroke, and VS will throw inexplicable errors and not clearly determine where the problem resides. Even under source control, I begin backing out changes and sometimes this works and sometimes it doesn't. This is the slowest development cycle I have had in 20 years... EXTREMELY frustrating!

Carlos MT 0 Reputation points2024-10-08T23:04:45.8833333+00:00 I have just installed Visual Studio 2022 (I had Visual Studio 2019), I am trying to create a MAUI app following the instructions, but when I run the app, I see all error messages like this:
"Severity Code Description Project File Line Suppression State
Error XLS0414 The type 'Application' was not found. Verify that you are not missing an assembly reference and that all referenced assemblies have been built."
It looks that I am not the only one experiencing this problem. Can Microsoft recommend me something? I can do nothing with MAUI.
