Last 2 days I've been plagued on my azure websites app with following exception:
Exception information:
Exception type: ConfigurationErrorsException
Exception message: The configuration file has been changed by another program. (D:\home\site\wwwroot\web.config)
It comes periodically each 5 minutes [or so], after app restart it goes ok for a while then it does again.
Is there a way how to debug what's causing the config file change? I have went through the whole code and have not found any reference for config file edition
Stack trace:

We have experienced the same problem but only at a specific time each day, starting three days ago.
It seems to be a global Azure issue, for more info take a look here

I found that when I publish with CLI like this:
dotnet publish -p:PublishProfile=FolderProfile
the published files work fine. But the published files produced by Visual Studio 2022 have the above error.
I have very simple .NET Core Web Api code that worked before in .NET Core 2.2 but stopped working after upgrading to 3.1
[HttpGet]
[Route("api/news")]
public IEnumerable<SyndicationItem> GetNews(string source)
{
var feed = SyndicationFeed.Load(XmlReader.Create(source));
return feed.Items;
}
I can invoke it by navigating to: https://localhost:5001/api/news?source=http://feeds.bbci.co.uk/news/rss.xml
In debug I can see it gets items just fine, but throws this error returning them, I don't understand why it stopped working after I upgraded to 3.1 and how to fix it
please advice, thanks!

The default JSON serializer in .NET Core 3.x is changed to System.Text.Json. In this case, you may need to specify to use Newtonsoft.Json as the default serializer (the default serializer in older versions of .NET Core).
In Startup.cs:
public void ConfigureServices(IServiceCollection services)
{
services.AddControllers().AddNewtonsoftJson();
// other settings in ConfigureServices...
}
i am use asp.net core 3.0 version for my project.
i create my webapi like this:
public IActionResult GetData()
{
var sql = "select * from aspnetusers";
var data = _base.GetDynamicBySql(sql) as List<IDictionary<string, object>>;
return Okļ¼data);
}
run the project and invoke the method,it give me a error info,it is like this:

i know,asp.net core had removed the newtonsoft.json,and use System.Text.Json to change it.
i use the configure in my project.startup file like this
services.AddControllers().AddNewtonsoftJson(o =>
{
o.SerializerSettings.ContractResolver = new Newtonsoft.Json.Serialization.DefaultContractResolver();
})
But it still doesn't work.
the project can be work in asp.net core 2.0,I want to know how to confiure my project , i want set my project use Newtonsoft.Json for default .

Any clues into fixing this would be much appreciated!!
Could be an environmental issue. Do you have same updates of .NET 2.0 applied on win 2003 and win 2008? Do you have any higher framework on win 2003?
Also, I found this article. The class that caused the exception is different but maybe it will help you or point you in right direction. Hope it helps.
I have an application that is making SOAP web service calls to another application (no JSON possibility here). Some of the responses come back fine. The issue is that one of the calls is made OK but the response brings back a System.DateTime.ParseExact error. I checked the date format in SOAPUI and it came back as: 2012-02-05-05:00
The error message is:

This does not look like a question (see note) but, in case I'm mistaken, here why...
case "date": return DateTime.ParseExact (value, "yyyy-MM-dd", null);
That's line #275 from XmlCustomFormatter.cs (source available on github) that shows the format (right or wrong) that Mono expect the date to be.
This does not match the 2012-02-05-05:00 string you provided in your question and this leads to the exception you're now experiencing. This could be a bug in Mono or, if Microsoft implementation behave the same, an issue with the web service you're calling.
note: bug reports be filled at http://bugzilla.xamarin.com
I've seen the this before a couple years back, it has stopped me porting several web service projects to Mono. I can confirm Mono behaves differently than than Microsoft .Net. I am not clear if it is a bug, but many web services return the date in formats other than 'yyyy-mm-dd', some add a 'Z' or other timezone spec, some have the time. You could patch Mono to use System.DateTime.Parse, but that a pain to have to use a custom Mono build just for this.
