Default Blazor PWA project cannot be host into IIS

I created a new Blazor project using Visual Studio 2019 (look at the picture)

I checked https, ASP.NET Core hosted and Progressive Web Application

After that visual studio creates the client project,the server project and a shared class project. I make sure that the project has no error so I compile it and run it on visual studio.

After that I want to host it into my IIS , so i go into the server project , right click , publish and I publish everything into my release folder.

Everything goes fine, now I go into my IIS , add new site, and select the path of the publish folder generated before (I used the port 80 for this test).

I also grant to the web config the IIS_IUSRS permission.

Now I type localhost:80 into my browser and I go into an infinite loop of waiting for the page that loads , but it never loads.

No errors are shown into the browser.

So I went into my IIS manager and say that the web config generated by default by visual studio is seen as wrong.

My webconfig.xml :

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <location path="." inheritInChildApplications="false">
    <system.webServer>
      <handlers>
        <add name="aspNetCore" path="*" verb="*" modules="AspNetCoreModuleV2" resourceType="Unspecified" />
      </handlers>
      <aspNetCore processPath="dotnet" arguments=".\Funzia.Server.dll" stdoutLogEnabled="false" stdoutLogFile=".\logs\stdout" hostingModel="inprocess" />
    </system.webServer>
  </location>
</configuration>
<!--ProjectGuid: 4872489F-5CAD-4DF4-BAFC-9D401F53BF48-->

I have installed ASP.NET core Runtime bundle also dotnet-hosting-2.2.2.

In fact I can easily host a Server App blazor , zero problems, but when I try to publish an Blazor WebAssembly App it is not working.

Other useful info:

The modules are not missing.

Output of dotnet --info:

I also tried to add an autosigned certificate and tried to access by https but I've experienced the same result as going with http.

More further I also tried to publish the project via console , I thought that maybe visual studio could create corrupted web config file, but the file created was the same.

I've found that also some other users are experiencing this problem but I have not found any solution yet.

Any suggestions?
