You explain in such detail, and make all of these resources available for free. You're a hero!
one of the best tutor in the world.
thanks to Venkat I am studying for my future job using this tutorial
Venkat is the King of .net.Thanks for .net core series.Pls upload quickly.Dont wanna wait :)
Very complete tutorial! Thanks for this work!
I am in till the end of the series. Very nice explanation. Many thanks.
Thanks Venkat for amazing content , Please I'm waiting the out of process hosting video .
Incredible Venkat!!!! Thanks again.
Hi Venkat it's really helpful for us ..thanks for these all videos
October 2020, Great Job and thank you again!
Thank you for this tutorial series!
I like the way you teach, thanks for putting so much efforts and record this course and make it available CZcams for free
DNYANESH WARADE Yes dear all course are free to us and he is genius personality
I think your courses are very well structured and clear. I hope you will explain Razor Pages too, and not just MVC
Venkate I'm taking notes of all the things you say that you will explain them in the future video tutorials, we depend on you that you will deliver videos on them, on Angular you mentioned some future tutorials but seems you got busy and you didn't keep track, like the image upload in Angular, thanks lot for the good work, everyday I'm checking on your new videos
Thank you very much sir for providing good content.
Nice videos, two thumbs up.
Maaaaaan........You deserve maaaany many more views.......thank you!!!!!!
Thankyou for the nice Tutorials
Thank you for the explanation.my question may wrong, have doubt if we use inprocess hosting method, will application run only iis in Windows???
Thank your sir.
#LoveFromNepal
Thank you so much for teaching us
I think you should explain the concept of In Process hosting model like where it is hosted, why it is introduced, what benefits it brings, how hosting is different from traditional .net framework etc.
Sir, kindly make videos on azure functions version 2 also. Kindly explain in those videos, how to perform blob storage, table storage, and queues storage in azure storage explorer using azure functions version 2 with visual studio 2017. It would be far better if you perform a complete CRUD operation in serverless micro services. You are such an excellent instructor. One of my best teachers.
Thank you.
Many people are waiting for Azure videos by Kudvenkat. Hope Kudvenkat sir realizes our expectation.
Great!!
What happens for "out of process" now is that when you execute "dotnet run", it builds your project (if you've made any changes) and then executes \bin\Debug
etcoreapp3.1\EmployeeManagement.exe, therefore the process name is EmployeeManagement.
To verify, follow these steps:
1. Execute "dotnet run" as instructed by venkat.
2. Open your Windows Task Manager, you will find EmployeeManagement.exe in there.
3. Right-click EmployeeManagement.exe and select "Open File Location". You will be brought to the foler where EmployeeManagement.exe sits in.
4. Ctrl-C out of dotnet run, and then manually execute EmployeeManagement.exe instead. Your will see the same messages shown in the console as when you executed "dotnet run", and then you can browse to localhost:5000 again.
thanks for uploading this video but please upload next part
great work
Sir very easy way can explain
Thank for providing such a very informative ASP.net core video
Really sir for who can't afford purchase the video tutorials you can provide all videos free
I never forget your contribution to build my career.
Nice!
A big thank you
Thank you!
Superb teacher!
Hi Venkat,
I'm very eager to understand the CreateDefaultBuilder() method which you said you'll explain after explaining the Main method in Part 6 of this series. But I do not see CreateDefaultBuilder() teachings in subsequesnt videos. Please help Sir.
A big Like
thank you!
The one true king
I noticed always in this series that it's like reading online documentation. It would be better if these videos are more on on-hand examples rather than explanation, we can read that online and we could understand that as we go along.. From the previous videos you mentioned many times 'I'll discuss in next videos' but in the next video I noticed you say that again so those things are getting stacked on us.
informative video
8:51 You said InProcess hosting model uses IIS or IIS Express but at this timestamp, you ran the app using CLI and we see it's using dotnet kestrel server, even though we had explicitly mentioned InProcess hosting model. Does that mean dotnet CLI uses Kestrel irrespective of the specified hosting model?
Sir please start a video series on Xamarin mobile development and on WPF.
Thanks.
I tried in VS2019 community edition to run the project in CLI, but in localhost:5000 displays the name of the project "EmployeeManagement" not the "dotnet". Why?
Same for me, I am using VS2019.
Same for me
Thank You
A question though, if In Process hosting uses IIS, does that mean the cross platform capability is only available for Out of Process hosting?
Thank you
You are doing a great job. May Allah (God) guide and bless you.
Thanks for sharing this valuable information. Maybe you can create tutorial about how to upload it to hosting server, like Asphostportal, Azure, or other hosting provider that support .net core.
Josef Bas Yes May be he will cover some hosting videos also in upcoming videos
HI Venkat when i try to open the blog it says Blog has been removed please look into it.
It means, if you run in CLI , by default it will use kestrel web server even though the application is in-process hosting?
So broi how can we publish an asp.net core website ? should we buy azure ? amazon ? why cannot publish as a casual asp.net website ? should we open our own hosting firm ? how should we publish to an using asp.net hosting service? not possible should we buy vps ? btw you are a gr8 teacher since 2010s
@kudvenkat It seems to be something strange in VS2019. When we use OutOfProcess then "System.Diagnostics.Process.GetCurrentProcess().ProcessName" is giving name of the project instead of "dotnet".
I'm glad I'm not the only one seeing this behaviour!
@Aman Pawar Use False property inside . Then it will give dotnet as a process name
Hi. My aspnet core webapp is printing iisexpress without putting that line InProcess
And when i run it with dotnet run the output is the name of the application, wich in my case is WebApplication2
The IIS web server is an old web server which has been in use for over 15 years by .Net community but the issue that came is that some applications which were built in that period were not compatible with recent technology and web services could not be used on them. Another issue was that as internet servers advanced the IIS web servers were not cope up to the speed of the internet servers making it slow, so a need for a faster web server became necessary. To do this, the .Net community used its set of previous information to create the most simple and quickest server ever possible and thus kestrel web server was born.
Anyways, read the below. This might help.

Great explanation for "Who is this new character Kestrel now?!!" Thanks a lot, it helped to know about what and why!
Is this in process and out of process related to load balancing in IIS ??
thanks
indian guy on youtube 😍😍
Hello Sir . I have my dotnet core 3.1 aapplication which previously deployed on iis. Now we have a requirement to host it using Kestral as a web server that is what you shown in above video , inprocess hosting. I have made the changes accordingly in my application and when i try to access the api after running from command prompt, as the project contains web api also then the error is coming which states that "An unhandled exception occurred while processing the request.
InvalidOperationException: No authenticationScheme was specified, and there was no DefaultChallengeScheme found. The default schemes can be set using either AddAuthentication(string defaultScheme) or AddAuthentication(Action configureOptions)."... Please help me sir
.NET Core is the future.
First of all, I really like your voice.
Secondly I could not understand one point. As kestrel server is using in out of process model. As in this video we have have set In process as process model in .csproj. so when you run the application by cli, why it is running in kestrel server. I think it should be iis server because we have set In process.
in Next lecture Kudvenkat explained that when we run asp.net core application from dotnet core CLI, in built kestrel is the only web server that will be used, the hosting setting in proj file will be ignored irrespective of the value InProcess or OutOfProcess
What is the difference if I start the app by clicking the "IIS Express" button or by clicking debug and then start without debugging ?
Hi venkat, When i tried to execute the above method in visual studio 2017. I am getting the Dot net as an output not an IIS express. Could you please tell me why?
Same problem
Same when I use Aspnetcorehostingmodel as Inprocess
And in startup.cs I use system.diagnostics code
But the output is dotnet....
Why
And if I change InProcess to OutofProcess the output is the remain same....dotnet....
Please tell me y.....
When project is being run through cli, it uses out of process hosting, right?? But isn’t it still mentioned as inprocess in csproj file !!
Hello Venkat SIr, I gave a system configuration inprocess and while running I can see display output as 'dotnet'. What all changes i need to do to see the iisexpress where asp.net core has been hosted.
I have the same issue. So I just updated my visual studio then when running my VS with issexpress it shows process name "iisexpress" on bowser.
For beginners ,I would recommend that do not change configurations first.
Follow these steps:
1. install matched version of .net SDK,hosting bundle and .net runtime with .net core
2. Try to use .net sdk 2.2 or 2.2 plus
I have followed these steps and resolve my problem.Hope it will help you guys.
Thanks.
Note : You are getting "dotnet" as output instead of "IIS Express" as hosting server that means your application is hosted as "OutOfProcess" hosting and it is using Kestrel server which is Asp.Net default hosting module.To clear this concept watch this and the next video in the playlist of OutOfProcess hosting.
Following along in 2020 with VS 2017. I get an error: warning MSB3026: Could not copy "obj\Debug
etcoreapp2.2\EmployeeManagement.dll" to "bin\Debug
etcoreapp2.2\EmployeeManagement.dll". If I shut down Visual Studio then Kestrel runs fine, but can only have command line version or Visual Studio version running at a time not both.
In 3.0 the HostingModel is by default InProcess. In 2.2 I liked it, because it was there explicitly but now I cannot find where it is, or I have to write it myself.
Its awsome. Sir record a video on linux server/ system locally
Hi Kudvenkat,
I have one question , Can anybody please help me, What is the thing that makes .net core cross platform that does not have to the .net previous version.
Please suggest your answers anybody.
Thanks.

i am on .Netcore 3.1 and I am only getting Dotnet as Output. Is it because of version Upgrade and packages are not included by default? Can someone please response ? And yes i am not running through Command Line but through Mac Visual Studio.
This hosting model is currently only applicable to IIS, which is the Web Server running on Windows. All other platforms have to use the OutOfProcess hosting model. Therefore, Visual Studio for Mac will run the app with the OutOfProcess hosting model, which uses the Kestrel web server (running under dotnet.exe).
My kestrel output is EmployeeManagement and not dotnet..... is it because i am using .net 5?
i am getting dotnet instead of iisexpress. but in aspnetcoremodel, it sets as inprocess only
When I run the code through command prompt of VS. It is showing 'EmployeeManagement'. It is not showing 'dotnet'. I am using asp.net core 3.1. Please help me.
This is ambiguous. If in Out Of process hosting there are two web servers (Internal and External) and you said that Kestrel can be used alone as edge server to take http calls then that is considered to In Process or Out process?
If you're hosting ASP.NET Core apps on Windows, then your choice is one of running your app in IIS*, or Kestrel (HTTP.SYS would be an alternative to Kestrel, but it's only available on Windows, so I don't care).
When you're going with IIS, then both InProcess and OutOfProcess hosting models are applicable:
- If you're opting for InProcess, then your app is running inside of an IIS worker process (w3wp, iisexpress). This has many benefits, as IIS is a fully-fledged web server/platform shipping with process monitoring (automatic restart on crash, recycling etc.), logging, authentication, etc. and you do not need to call another webserver in order to fulfill any requests, which may increase requests/s.
- If you're opting for OutOfProcess, then your app will use the Kestrel web server, and run in a separate process (not inside w3wp or iisexpress). IIS, which is the public facing webserver, has to forward any incoming requests to Kestrel in order to fulfill them. Next to no process monitoring, logging or any other benefits IIS could possibly deliver, you'll notice that the requests/s are less compared to when running the app in the InProcess hosting model due to the forwarding/proxying.
Were you to skip the use of IIS on Windows, you could instead host your app using Kestrel. Kestrel now becomes the public facing web server. As the InProcess hosting model is (as of this date) only applicable when using IIS, you'd default to using the OutOfProcess hosting model.
If you're hosting ASP.NET Core apps on any other platform, then only the OutOfProcess hosting model is applicable (and should be honored by your runtime). So even if you set the hosting model to InProcess, you'll end up with the OutOfProcess hosting model, where your app is hosted in Kestrel. You'd most likely use Apache or NGINX as the public facing web server though, and have them relaying to Kestrel (kind of like the IIS + OutOfProcess model above).
* Apache/NGINX can also be used as public-facing web servers, acting as a reverse proxy to your app. See docs.microsoft.com/en-us/aspnet/core/fundamentals/servers/kestrel/when-to-use-a-reverse-proxy
When I run the project using dotnet run command, I am getting "EmployeeManagement" as the process name rather then "dotnet" as the process name. Can anyone tell me why?
await context.Response.WriteAsync(System.Diagnostics.Process.GetCurrentProcess().ProcessName);
the result in browser is "dotnet" don't show iisepress update visual or wrong?

Will you make a React tutorial anytime in future
Hi Sir, dotnet run command does not working for me, it gives my project name instead of process name please suggest me thanks
Sir, I have followed your creating new project vedios I have created the same but in project file there is no Inprocess not added in my project
@sinchana, in next video hopefuly you will get your answer. if there is no setting in csprof file, it means OutOfProcess which is by default.
You might have already done this by now but if you haven't then please add the above line in the PropertyGroup of csproj file.
This Microsoft document says the opposite. It says, "ASP.NET Core apps default to the in-process hosting model."
docs.microsoft.com/en-us/aspnet/core/host-and-deploy/aspnet-core-module?view=aspnetcore-3.1#in-process-hosting-model
When I am running my project from CLI instead of process name "dotnet" I am getting my project's name "EmployeeManagement". Why is this happening?
I get the same thing. Maybe the latest Kestrel prefers to present your application name instead of itself.
Should i watch asp.net videos before watching these videos?
Hi Nishant - Not required. You can start directly with ASP .NET Core. Hope this helps.
Hi, I'm using vs 2019 with .net core 3.1. After running 'dotnet run' command on cli I get my project name as process name.
Is this due to some changes in version 3.1 ?
I have the same issue, were you able to find what is the issue.
@@gopinathselvaraj478 not yet, have you? Will get back if I get the answer.
Looks like that's how it is in .net core 3.1, haven't been able to find any answer for this.
Have you guys able to resolve the issue? I am having same issue.
@@EpinderSingh Read on a post saying that's how it is with .net core 3 and above. It is not a show stopper, happy learning 👍🏽
On running my code by adding System.Diagnostics.Process.GetCurrentProcess().ProcessName in startup.cs file, instead of IISExprees I got dotnet in the browser. Why is there difference in my case? Am I doing anything wrong?
If u have an answer do let me know
This is because in ASP.NET core the default hosting Process in OutOfProcess. In your case the ASPNetCoreHostingModel node might not be there and hence the default hosting model is coming as dotnet. Hope it helps.

Hello Venkat, in .net core 3 the name of the out of process hosting model changed to the name of the project, not 'dotnet', why? So if your project is called WebApplication1, then that's the name of the process.
This is not my comment .
What happens now is that when you execute "dotnet run", it builds your project (if you've made any changes) and then executes \bin\Debug
etcoreapp3.1\EmployeeManagement.exe, therefore the process name is EmployeeManagement.
To verify, follow these steps:
1. Execute "dotnet run" as instructed by venkat.

For InProcess hosting I am getting processname as "dotnet" instead of "iisexpress" while running the app from visual studio. Can anyone explain the reason?
