I am facing following error in our React with .NET core 3.1 application. Our application was working perfectly until yesterday. Today my system auto rebooted post windows auto updates after that my application stopped working.
The home page is blank and the following error in chrome and Edge browser.
"Failed to load resource: net::ERR_HTTP2_PROTOCOL_ERROR"
Updating Visual studio to Version 16.9.7 fixed the issue for me.

See some discussion here, they mention that the root cause is KB5003637 windows update installed. It also happens in my case: two days ago the app started to have errors like yours.
One of solutions is to uninstall the patch until MS releases a second patch.
I can add that I'm getting the same error in Blazor. I thought it was just a VS thing, but my live website is also failing randomly (about 1 time in 20). So it looks a lot like a Windows problem.
I finished developing a professional portfolio website for myself (since I will be graduating this May). Everything looked great when I was using the development server. However, after I tried to deploy it to GitHub Pages, only a blank screen shows. The site should be reachable at https://shaynajrosado.github.io/Portfolio.
After getting frustrated, I tried seeing whether hosting it on Firebase would make a difference.

Still, nothing shows up.
This links to a picture of the error message I get when I right-click on the blank page & Inspect
After clicking the error message, it takes me to the React website which translates the error message into: "e(...): Nothing was returned from render. This usually means a return statement is missing. Or, to render nothing, return null."
However, in my code, there really aren't any return statements missing. Below is a link to the project repository:
https://github.com/shaynajrosado/Portfolio/tree/gh-pages
I currently have the project set to use branch gh-pages as the source.
Any words of advice would be very greatly appreciated as I continue to wrestle with this!
I know this is a repeated question, but still I am posting the question as I unable to find the answer by all the method i check in the previous links. So, please help me instead of marking duplicate or voting down.
I have build an app with some cordova plugin including the push notification, but in some handsets its working good and in some its showing me as "Unfortunately appname has stopped" and the app is exits.
I have tried with some options like updating google play services, sdk update, adb logcat, keyboard uninstall and install, even platform also i have added again but no use.
Please save me from the bug.
Ultimately I have found the solution.
The error was the cordova-android#7.0.0 version.
I just updated my package from 7.0.0 to 7.1.0 and just re-installed all the plugins and its working pretty fine.
Now all the plugins even the push notifications are working good.
If anyone has the issue can just follow the same procedure and it will help you.
I have deployed a sample application into Android emulator. Its executing, however its giving wrong output. How to debug it?? and If error comes while opening the page in emulator, where i can see the entire log??

I've just started getting this Javascript error running VS2010 with SL4
Error: Unhandled Error in Silverlight Application
Code: 2104
Category: InitializeError
Message: Could not download the Silverlight application. Check web server settings
Everything was working fine, changed 1 line of code to use a RegularExpression in the web project (using the Silverlight Business Application template) then when rebuilding I get this error.
Google says this is IIS and mimetype related. I'm using Cassini not IIS with VS2010.
Rebooted, cleared xap from IE cache. Error on both IE and FF.
What could be wrong?
I just got this error myself. Looking at source control and my project I noticed that the original test pages that were created when I setup the project got replaced by two new test pages (one .aspx and one .html).
I removed the newly created pages and went back to the old test pages and things started working.
If your situation isn't the same as mine, then just check your silverlightControlHost div in your test page and make sure you are pointing to the correct .xap file and runtime.
if youre not running in IIS then just check your silverlightControlHost div in your test page and make sure you are pointing to the correct .xap file and runtime.
If you were in MVC you could do something similar...
<param name="source" value="#Url.Content("~/ClientBin/NameOfYourSlAppGoesHere.xap")" />
Follow the Step :
On Hosting project, Properties > Silverlight Applications > Add..
This solved my Problem.
Simple error.
I had the same error with my provider. When I looked at the MIME type everything seemed to be OK:
.xap => application/x-silverlight-app
which seems to be the default value on IIS 6. Then I looked at the webpage VS 2010 created and noticed that it has a MIME type of
application/x-silverlight-2
I changed the MIME type on IIS according to the webpage's type and - my silverlight application gets loaded without any error!
This error often occurs because the MIME type is not set, as you have found for yourself. It can also be a mask for the HTTP error. You can see the message by pulling up the XAP file directly from your browser (http://yourwebsite/ClientBin/filename.xap). The file will either attempt to download, or it will show you an HTTP Error.
I also had the same issue on VS 2010. And the reason was that the .xap file was not getting copied to ClientBin directory of the hosting web site project.
Reason was the association from the hosting web site project to the silverlight project was missing for some reason. (should be due to some restructuring of the projects that I've done recently in my case)
I had to re-add the association from the hosting web site project to the silverlight project.
Steps:
On Hosting project, Properties > Silverlight Applications > Add..
I faced a similar issue and it was solved with the help of this blog post: http://vanderbiest.org/blog/2009/10/27/2104-silverlight-initialization-error/
Just ensuring that IIS_IUSRS has read and read & execute permission on the XAP file might fix this issue.
.xap file was not getting copied to ClientBin directory
The problem in my case was that http://mysite/ClientBin/MyApp.xap was returning a 404. The build process was copying the XAP file into /ClientBin/DEBUG/ - I expect this is because someone told it to copy the XAP file to a config specific folder. To fix it I did the following...
Go to the properties of your website.
Go to the Silverlight Apps page.
If your Silverlight app is already referenced there, remove it.
Now click Add.
Select your existing SL app.
Make sure "Copy to a config specific folder" is NOT checked!
for my case it occured In IE and in chrom the project work.
it resolved by
disable protected mode in IE.(Internet Option -->Security)
For my case (with visual studio 2012), one of the projects in the solution wasn't loaded...
right click->reload project.
fixed.
