ABP SUITE 5.3.2 - Adding an entity to a module makes the module unusable, cannot compile, reference/namespace issues in the blazor project + Very slow to create a module. #3472

• ABP Framework version: v5.3.2, Suite
• UI type: Blazor
• DB provider: EF Core
• Tiered (MVC) or Identity Server Separated (Angular): yes
• Exception message and stack trace: (see screenshot)
• Steps to reproduce the issue:"

1. Using ABP Suite, create a new solution: Blazor, EFCore, Tiered: Yes
2. In the module section, create a new module (MyNewModule) and wait... and wait... and wait...
   1. What can take so long ?!?!? Oh, yeah... the "super fast" yarn !!! 7 minutes run-time after the 20 seconds time taken to create the module ! But ?!?! Wait ! Where are the sub folders .\angular and .\hosts ?!?!? They got deleted ?!?!? This means that I had to wait 7 minutes for yarn to complete his tasks on projects/folder that got deleted at the end of the module creation process ?!?!? Come on ! Was this really needed ?!?!?
3. in VS, load/reload solution, compile, run and make sur everything works until now. (Should be good at this point !)
4. Add a new entity to the newly created module...
   1. Return to main screen and click "add an existing solution"
   2. Enter the path of the newly created module (a browse window would be nice here !)
   3. Add a new entity, with only one property and click save and generate (and be surprised of how fast it could be to generate almost 30 files in less than 2 seconds !!!)
   4. Try to compile and see all the errors...

After having struggled couples of minutes to find a work around, I had the idea to try something, add the "global::" prefix before the "namespace!" inside the the razor page and then I was able to compile the project without any error.

But, I'm not sure if it's a good thing and that we should do have to do this... Anyhow, ABP Suite needs a fix for this I think, right ?

Thanks
