I have built a working C# application, a multi-threaded application that crunches numbers for research.
I can only go so far with my own PC, so I'm wondering if there exists a service where I can rent a high powered computer that can run my C# code. Something with a lot of processor cores, so I could run... say, 64 threads concurrently.
Windows Azure can do that. Just install a VM and create an as big machine as you need.
Troy Hunt wrote a good blog post about how he used a cloud SQL Server for that kind of job.
In windows Azure you can create your service model, can specify the size to which to deploy an instance of your role, depending on its resource requirements.
Amazon EC2 also provides a number of options to choose an instance as per your requirement.

I'm a C# ASP.NET junior dev and have worked with Code First C# Databases, RESTful API's, MVC & Vue (a frontend framework sort of like React) to create websites.
Now at work and during my education, I've never handled deployment.
At this time I have a personal project. I have succesfully hosted my relational MySQL Database on phpMyAdmin and can update it from my local desktop.
My hosting site let me know they do not host C# or anything of the sort.
I found some posts suggesting Azure, AWS, others, but for every post I find I find equal people protesting those.
What is a good site to host my first REST API? I'm looking for something that can go beyond Minimum Viable Product and I'd like to host my website under the hosting service I'm currently using (so not paired hosting with the API).
What would the costprice look like for an API that's deployed and being used by clients?
I realize this cost depends on the amount of traffic, but assume a basic API used for, let's say, posting orders in an online shop (though website/app/w.e, it all would communicate through the API).
Any tips are welcome as I feel I'm swimming in the dark researching this.
Thank you
Any hosting service that grants you real access to a machine will be able to run your API as some specialized for the .net/core ecossystem.
I supposed you know about php based on phpMyAdmin service and the ecossystem of hosts that support php, although cheaper they do not exactly give you access to the machine and probably will not support .net/core as inumerous others tech stacks.
As a Junior Developer I believe you should have a little bit of practice in any deployment ecossystem so I encorage you to try most of the big clouds (Azure, GCP, AWS), but also some smaller hosts to gain experience and understand a bit more about the differences in deployment and ecosystem.
Azure will be really easy, you can create an account and post your API without any costs using an free WebApp, VS will even have publishing tools that will handle 90% of the job, GCP will be a little trickier and will require you to know a bit about containers and clusters, if you go for a non specilized host like digitalocean you will need to understand more about the Operational system and associated servers/controllers to deploy and publish
about the cost part is a lot more difficult. It will depend on the host that you are using and the load (process, memory, size, and throughput of data). In my experience I had some very small-scale APIs that required more processing or memory to accomplish some tasks like PDF generation than a medium-scale API that only had json data transaction
I've scenario to create an application(Windows service , Winforms app) which runs twice every day automatically on users PC. These Users are internal employees in the same network. So at morning and evening this application has to run. But it doesn't need to show any window or information saying its running. Its good to have a simple notification in system tray that its started execution.
My experience in with web application development. So I got a little stucked with these such application on deciding which is best.What my understandings are if its a standalone exe, we could ask all users to download the exe and install.
If its a windows service we may depend up on instalutil to install the service.
So I really needs an advice on this. The application is nothing, just requesting a TFS api and the resulting JSON has to store in Table. So the JSOn will be based on each user using their windows authentication.
Please suggest a good solution to achieve its the best,secure and easiest way even for non tech savvy users.
Instead of all user communicating to TFS server twice a day i guess better way is to install a service in one centralized machine which will run a window service twice a day and that machine will host that service using WCF so that other user will communicate with machine this will help you to distribute the load of tfs api. i used the same approach in my case where one machine talk to ALM and other talk to that machine to get the files.
Creating a window service is pretty simple and straight forward.
Follow the link to make one:

You can host the service in WCF using IIS, TCP, Webservice, Console application its upto you. Follow this link

Hey guys, I was working on a simple chat program to brush up on my C#, and ran into a roadblock. I wanted to allow one computer to broadcast its location, and the other to find that computer, and display it (and any others) in a list.. Just a push in the right direction would be great,
Thanks,
Max
Mono.Zeroconf is a .NET library that provides common zeroconf opertations - service publish and discovery. It uses Apple's Bonjour for Windows as a transport on Windows.
Developers can publish services that will be exposed to other computers on the local network and also query the local machines on the network for services that could have been exposed.
See Peer-to-Peer Programming with WCF and .NET Framework 3.5.
All you need is to share destination PC. and then run your web-based application on the target pc IIS.
Updated Part :
If you have awindows application and want users use that application youhave some solution
create a Login form for your application
use from MarshalByRef object and create a Channel between user andaplication
create a MSI (setup) and run it from server (in entire Active Directory).this will install one application in each client
create a simple dot net setup. justRight click onyour windowsproject in VS and then select Publich, in the wizard walk through creating a network application
I think the last option is closest one to your request
Use AD (Active Directory)? Or some such [which would serve as] central messageboard mechanism - maybe even MSMQ?
I'm working on a graduation project for one of my university courses, and I need find some place to run several crawlers I wrote in C# from. With no web hosting experience, I'm a bit lost. Is this something that any site allows? Do I need a special host that gives more access to the server? The crawler is a simple app that does its work, then periodically writes information to a remote database.
A web crawler is a simulation of a normal user. It acess sites like browsers do, getting the html code (javascript, etc.) returned from the server (so no internal access to server code). Being that, any site can be crawled.
Be aware of some web crawler ethics guidelines. There are pages you shouldn't index or follow its links. And web developers build some files and instructions to web crawlers, saying what you can index or follow.
If you can't run it off your desktop for some reason, you'll need a host that lets you execute arbitrary C# code. Most cheap web servers don't do this due to the potential security implications, since there will be several other people running on the same server.
This means you'll need to be on a server where you have your own OS. Either a VPS - Virtual Private Server, where virtualization is used to give you your own OS but share the hardware - or your own dedicated server, where you have both the hardware and software to yourself.
Note that if you're running on a server that's shared in any way, you'll need to make sure to throttle yourself so as to not cause problems for your neighbors; your primary issue will be not using too much CPU or bandwidth. This isn't just for politeness - most web hosts will suspend your hosting if you're causing problems on their network, such as denying the other users of the hardware you're on resources by consuming them all yourself. You can usually burst higher usage levels, but they'll cut you off if you sustain them for a significant period of time.
This doesn't seem to have anything to do with web hosting. You just need a machine with an internet connection and a database server.
I'd check with your university if I were you. At least in my time, a lot was possible to arrange in-house when it came to graduation projects.
Failing that, you could look into a simple VPS (Virtual Private Server) account. Unless you are sure your app runs under Mono, you will need a Windows one. The resource limits are usually a lot lower than you'd get from a dedicated server, but they're relatively affordable. Some will offer a MS SQL Server database you can use next to the VPS account (on another machine). Installing SQL Server on the VPS itself can be a problem license wise.
Make sure you check the terms of usage before you open an account, as well as the (virtual) system specs though. Also check if there is some kind of minimum contract period. Sometimes this can be longer than a single month, especially if there is no setup fee.
If at all possible, find a host that's geographically close to you. A server on the other side of the world can get a little annoying to access remotely using Remote Desktop.
80legs lets you use their crawlers to process millions of web pages with your own program.
The rates are:
$2.00 per million pages
$0.03 per CPU-hour
They claim to crawl 2 billion web pages a day.
You will need a VPS(Virtual private server) or a full on dedicated server. Crawlers are nothing more then applications that "crawl" the internet. While you could set up a web site to be a crawler, it is not practical because the web page would have to be accessed for you crawler to work. You will have to read the ToS(Terms of service) for the host to see what the terms are for usage. Some of the lower prices hosts will cut your connection with a reason of "negatively impacting the network" if you try to use to much bandwidth even though they have given you plenty to use.
VPS are around $30-80 for a linux server and $60+ for a windows server.
Dedicated services run $100+ for both linux and windows servers.
You don't need any web hosting to run your spider. Just ask for a PC with web connection that can act as a dedicated server,configure the database and run the crawler from there.
Is it possible to create a C# EXE or Windows Service that can process Web Service requests? Obviously, some sort of embedded, probably limited, web server would have to be part of the EXE/service. The EXE/service would not have to rely on IIS being installed. Preferably, the embedded web service could handle HTTPS/SSL type connections.
The scenario is this: customer wants to install a small agent (a windows service) on their corporate machines. The agent would have two primary tasks: 1) monitor the system over time and gather certain pieces of data and 2) respond to web service requests (SOAP -v- REST is still be haggled about) for data gathering or system change purposes. The customer likes the idea of web service APIs so that any number of clients (in any language) can be written to tap into the various agents running on the corporate machines. They want the installation to be relatively painless (install .NET, some assemblies, a service, modify the Windows firewall, start the service) without requiring IIS to be installed and configured.
I know that I can do this with Delphi. But the customer would prefer to have this done in C# if possible.
Any suggestions?
Yes, it's possible, you may want to have a look at WCF and Self Hosting.
Yes, it is possible (and fairly easy).
Here is a CodeProject article showing how to make a basic HTTP server in C#. This could easily be put in a standalone EXE or service, and used as a web service.
One technology you might want to check out is WCF. WCF can be a bit of a pain to get into but there's a great screencast over at DNRTV by Keith Elder that shows how to get started with WCF in a very simple fashion.
http://www.dnrtv.com/default.aspx?showNum=135
You could take a look at HttpListener in the .Net framework.
I would highly recommend WCF. It would fit very well into a product like you are describing. There are a good number of books available.
Sure, you can do that. Be sure to change the Output Type of the project to Console Application. Then, in your Main function, add a string[] parameter. Off of some switch that you receive on the command line, you can branch to ServiceBase.Run to run as a Windows Service or branch to some other code to run a console application.
This question is somewhat older but since I needed something similar some time ago it felt like this question is still relevant.
I wrote a small Rest-API with NancyFx and OWIN. OWIN is a standard interface between .Net applications and web servers. With OWIN it is possible to create a self-hosted WEB-API. Nancy on the other hand is
a lightweight, low-ceremony, framework for building HTTP based
services on .NET ยน
The combination of those two makes it possible to create a self-hosted C# Web service.
I am quite sure that there are many more possibilities to create something like this by now but since I used it like this I thought the Information might be useful to someone.
