• opened MonkeyFinderHybrid.sln in VS 2022

• NuGet packages were restored automatically;

• rebuilt was OK:

• I see the similar to the subject issue discussion here Question: The project needs to be deployed before we can debug but no (?) effective solution.

Do you have an effective solution of the subject issue? Did you try to go through your tutorial "Part 2 - Add Monkey Dialog" source code on a fresh PC?

continued...

Target deployment folder S:\Learning\Blazor\blazor-hybrid-workshop-main\Part 2 - Add Monkey Dialog\MonkeyFinderHybrid\bin\Debug\net8.0-windows10.0.19041.0\win10-x64\AppX\wwwroot\_content\Microsoft.FluentUI.AspNetCore.Components\Components\DesignSystemProvider

exists. But is has blanks. Could these blanks be the source/cause of the subject issue? Let's check:

When the whole solution folder with all the files was moved to the S:\Learning\Blazor\Issue folder, NuGet packages restored, solution cleared, closed, rebuilt then the The project needs to be deployed... issue disappeared. So I can assume the subject issue was caused by the target deployment fullpath having blanks.

But when I have tried to run the project's first time the result program window was:

After a few more tries I have got the positive result program window:

Still unclear why on first runs the result was an "Unhandled exception" (debug/trace mode didn't allow to catch the source of this error).

So the recommendations would be:

• to change the naming of the tutorial chapters for them to not have blank (or hyphen/dash - '-' ?) chars;
• to introduce unhandled errors handling code in the very first sample project.
