I have clone the project from source url. My friend has developed the asp.net core web application using .NetCore 1.0.0-preview2-003121 sdk. However on my pc I have install .NetCore 1.0.1-preview2-003131 sdk. I am getting the error. I changed the version in the global.json file as you can see below but still no solution.I google it but all the solution are not working for me.

An error occurred attempting to determine the process id of dotnet.exe which is hosting your application. One or more errors occurred.

That problem can occur when three things are true:

  1. your app is trying to run with SSL,
  2. your app does not have an SSL Certificate setup, and
  3. you are debugging your app (which is preventing SSL certificate setup).

As a quick fix attempt, run the app without debugging via Ctrl + F5 or view the app in the browser via Ctrl + Shift + W. That might install the SSL certificate for you. If it does not, consider changing your app's launch settings from HTTPS to HTTP. If you really need SSL, you'll have to figure out how to install and use an SSL certificate on your local machine.

Checkout out these on GitHub and StackOverflow.

Note that for IIS Express to work with SSL, the port needs to be in the 44300 through 44399 range (from How do I fix a missing IIS Express SSL Certificate? -original article https://docs.microsoft.com/en-us/iis/extensions/using-iis-express/running-iis-express-without-administrative-privileges)

For other ports Visual Studio 2017 didn't install the SSL Certificate, but I was able to install it as suggested in How do I fix a missing IIS Express SSL Certificate?

From an elevated command prompt run (specify your port number):

cd C:\Program Files (x86)\IIS Express
IisExpressAdminCmd.exe setupsslUrl -url:https://localhost:55555/ -UseSelfSigned


回答3:

This may happen when you try to run your application with the "Enable SSL" setting enabled, and if the self-signed certificate has not been installed as a trusted root certificate.

To fix, follow these steps:

  1. Press CTRLF5 to start your application and have VS create the self-signed certificate.
  2. If the application did not start in Internet Explorer, open an IE window and copy/paste the start URL into that window.
  3. IE will display a certificate warning. Click "Continue to this website."
  4. Click on the red certificate error symbol in the address bar and then "View certificates".
  5. In the dialog that opens click "Install certificate...".
  6. In the certification installation dialog choose "Local machine", (not "Current user"), then click "Next".
  7. Select "Place all certificates into the following store" and in the "Browse..." dialog, select "Trusted Root Certification Authorities".
  8. Complete the installation dialog, then close and reopen the browser tab. Now no certificate error should be displayed.

You are all set now to run your project with F5 in debug mode.



回答4:

I had this same issue, eventually realizing that I had set up an HTTPS URL Rewrite in my application's web.config for use in production. However, I didn't want to mess with SSL in my dev environment, so I decided to remove it.

After deleting the section and attempting to debug the app again, I noticed that Chrome kept redirecting my localhost to HTTPS, in spite of the fact that I hadn't selected "Enable SSL" in the application properties.

What finally got my app debugging locally in HTTP again was clearing my Chrome cache.

Hope this helps someone else who's stuck!



回答5:

I have a .NET Core app and I had accidentally changed my IIS settings launchSettings.json to use https instead of http. Reverting that change automatically fixed my issue.



回答6:

Please remember always to declare your new IIS Web Site in hosts file inside System32 folder if you are using Windows. This was my case, feeling dump!



回答7:

If you are using IIS (not Express) a simple Stop and Start of it did the work.



回答8:

I solved it by doing the following steps:

  • Copying the appsettings.Development.json from the Solution folder to \bin\Debug\netcoreapp2.0
  • Rename it to appsettings.json

Worked like a charm for me.



回答9:

I fixed this by doing:

CMD:

netsh http add iplisten ipaddress=192.168.xxx.xxx

then control + c to exist, then iisreset



回答10:

I ran into the same issue and what i did to fix was in my launchSettings.json I added this line of code and do not change the http to https or you will get the same error

"iisSettings": { "windowsAuthentication": false, "anonymousAuthentication": true, "iisExpress": { "applicationUrl": "http://localhost:add your localhost Id", "sslPort": 44342 }



回答11:

Make sure your IP address hasn't changed (if using a DNS name)

Whether using 'real DNS' or an override in hosts make sure your local IP hasn't changed.

If you're using NAT and you don't have a fixed local IP assigned to your machine this is very easy to do. In fact it could be months before you are issued with a new IP making it all the more confusing!

I had an entry

192.168.1.134 dev.example.com

in my hosts file, but my local IP changed to 192.168.1.136.

You can probably use 127.0.0.1 instead.

After fixing this for my case I had to restart Visual Studio, and also full IIS (not sure why).

PS. I actually set 192.168.1.134 in my 'real DNS' to facilitate testing on mobile devices with a proper DNS name and certificate. So when this changes it breaks.
