Describe the bug

After creating a new AspNetCore app using the "react" template, publishing it results in a blank screen and a 404 error.
The files inside wwwroot seems to be ignored.

Expected Behavior

Starting the published app should display the react app.

Steps To Reproduce

1. dotnet new react -o my-app
2. cd my-app
3. disable the https redirection (for local startup) : // app.UseHttpsRedirection();
4. dotnet publish -c Release
5. dotnet .\bin\Release\net7.0\publish\my-app.dll

Exceptions (if any)

No response

.NET Version

7.0.100

Anything else?

One thing to note is that if I add an index.html in a manually created wwwroot, then disabling the csproj target that publish the spa app, the app was able to start correctly.

I am still getting the issue, even in incognito mode, and on an other browser.

I created a repository : https://github.com/julesrx/aspnetcore-issue-45165
I will try to setup a more reproducible environment.

@julesrx I found the issue.

You are not launching the app from the right working directory. dotnet .\bin\Release\net7.0\publish\my-app.dll will launch the app from your my-app working dir, so the content root is not right. If you navigate to the publish folder and launch it from there, it will work.
