Troubleshooting a Blank Page When Running a .Net Blazor website

Question

I'm running a website in Visual Studio, but when I load it there's just a blank page, not even a loading screen. And with nothing showing up in the inspect tool. Any suggestions on what could be causing this issue?

Answer 1

I just realized, I did not actually have a index.html file. I am still very new to ASP.NET Blazor. But now it looks like my app is working, but when I build it, it does not generate the blazor.server.js Thank you!

Hey there Ryan G

Good question and thanks for using the QandA platform

A blank page in your Blazor website can cause a lot of reasons

let me drop you a few troubleshoots, hope they help

Even if there's no visible content, open your browser's developer tools-F12 and check the console tab for any error messages. These can provide about what might be going wrong.

Look at the network tab in the developer tools to see if your application is making any requests and if they're returning successfully.

Ensure that you're using a browser that supports WebAssembly, which is required for running Blazor applications. Also, try clearing your browser cache or using an incognito/private browsing window to rule out any caching issues.

Check your Startup.cs and Program.cs files for any misconfigurations, especially related to routing and service registration. Make sure your Blazor components are properly referenced and configured. give it a recheck

Finally Double-check your .cshtml files and component markup for any syntax errors or missing components. A single misplaced tag or component could cause the entire page to render blank.

If this helps kindly accept the answer thanks very much.
