I have several clients who are using web application hosted in their local IIS server at different locations. Currently all are using version 1.0.
I published the new version of the application say version 1.1, zipped and host in http server at location X.
My application can check if new version is available or not. Now what can be done so that v1.0 at client side can be replaced with new version i.e. 1.1. I want the v1.0 running at client side, automatically (of course with user permission) downloads the v1.1 from http server using internet, extracts the file and host itself in local IIS server.
Is their any method like ClickOnce for web application? I have build the application using asp.net C#. Any 3rd party application or C# code sample would be useful.
I came across your question, if you want to make web apps that are self updating, you can check a solution here http://haacked.com/archive/2011/01/15/building-a-self-updating-site-using-nuget.aspx/, as for updating database, you can add a bootsrapper class that if you are using nHibernate use SchemaUpdate(config).Execute(true, true); that you call on site/index to ensure that the schema is updating. hope thats help

I am still relatively new to writing API's and web services, so bear with me if I use incorrect terminology.
I want to know if it is possible to create an API in C# using nancyfx (or any other framework) or even just a simple web app and then set it up as a continually running web service using WampServer. I'm pretty new to Wamp, all I have done so far is create a few rudimentary pages with php; but I can't seem to find any information about running a web service with Wamp using a different back end language other than php.
WAMP is stand for Windows Apache MySQL PHP. As I can say, you can't run a C# web service with it base configuration. However, you actually don't need this. If you are on .net Core, there is a Kestrel web server. You can use it to serve your app. On a .net framework you have a HttpListener which can help you to implement self-hosted web service (for example, a windows service which hosts your application).
There are many other options, btw. Try google for some kind of "Hosting .net web application" or "Self-hosted .net web application"
I have a small question which ends in a big topic.
Is it possible - and yes how - to use C# code in a SharePoint 2013 Hosted App?
I tried to have a .asmx file within my project.
Then I get this error.
#"Error 1
CorrelationId: 9c1ea930-a131-4f5b-bff5-8a1a61fe34d9
ErrorDetail: There was a problem with activating the app web definition.
ErrorType: App

ExceptionMessage: Microsoft.SharePoint.SPException: Exception from HRESULT: 0x81070964 ---> System.Runtime.InteropServices.COMException: Exception from HRESULT: 0x81070964
And then I tried a few tutorials like...

http://social.technet.microsoft.com/wiki/contents/articles/24194.sharepoint-2013-create-a-custom-wcf-rest-service-hosted-in-sharepoint-and-deployed-in-a-wsp.aspx
But sometimes I didn't understand correctly or sometime I have other problems during compile everything.
I had a problem with getting assembly id/name, too. Because there was no compiled DDL File for the project.
What I want in general?
A .app file with a SP Hosted App (for SP 2013) which includes a web service for SP Client Object Model.
So I thinking about using the "default.aspx" with CodeBehind. So I could execute scripts "behind" the aspx. But then it couldn't find the assembly... Or there was something else.
Could anyone help me? If you have some ideas you could !please! provide them to me. Thank's!
SharePoint hosted Apps doesn't allow server side code to be excuted on the server, this is the whole idea of SharePoint Apps, nothing should be executed in the SharePoint Front End Servers. Unlike Farm solutions, SharePoint Hosted Apps runs on the client and can only access SharePoint resources through a predefined set of services that can be called either using REST or JSOM.
If you need a custom code, you can create a WCF service, deploy it under ISAPI and call it from your App, but this will not be doable in SharePoint online.
As for your question, you can use ASPX pages of course, but you will never put a code behind for it, as these pages are stored in a Pages Library and by design, it is stored in the content DB, so any code execution is denied.
Only aspx pages that are stored on hard disk like the _layouts pages can have a code behind.
SharePoint App runs in client context. You can create SharePoint App just using JS, HTML, CSS, JSOM. You cannot use C# for App (excluding CSOM, you can use it for creation remote event receiver for example)
If you need to implement some functionality to on-premise version of SharePoint, use traditional server-side solutions, not App.
It's important to understand the difference between SharePoint-hosted Apps and Provider-hosted Apps:
SharePoint-hosted Apps
SharePoint-hosted apps, or apps where all components are hosted on either an on-premises or Office 365 SharePoint farm. SharePoint-hosted apps are installed on a SharePoint 2013 website, called the host web. They have their resources hosted on an isolated subsite of a host web, called the app web. The App is created using HTML/JavaScript with CSOM or REST calls
Provider hosted apps
Provider-hosted apps for SharePoint include components that are deployed and hosted outside the SharePoint farm. They are installed to the host web, but their remote components are hosted on another server. The App run in a server that is external to SharePoint's. It has its own infrastructure and the Provider is responsible for keeping it running. They allow you to use Server Side code and uses the .NET CSOM.
This image will give you an overview of different Hosting solutions:

The SharePoint Add-in model uses ASPX pages, which can also include ASPX controls. However any methods called are restricted to client-side scripting - i.e. JavaScript and SharePoint's JSOM (JavaScript Object Model), which is a subset of the Client Side Object Model.
I need to design an HTML 5 responsive, and simple app that should work on both internal Win server and on Azure.Our Client wants to check out Azure but maybe later he will want this app to be on its own on premise servers. Our Developers are almost all .NET back ends, with basic knowledge in HTML 5, Javascript, Jquery, and bootstrap. We accepted the challenge because the project is tiny and interesting, the point is, is possible to have 1 project that can be deployed to azure or IIS with no problem? and what kind of project should we create? I think that a simple asp.net project with some web methods and js will do the job, but I don't know if it will work on azure too. Back n 2010 I did something that way but now I am not sure it's still valid
Important: the web application should be able to query oracle on premise server, via web service but not sure if take azure service bus or azure vpn
It depends on how you build your application. I have built applications in the past that works both on-premise and on Azure. As long as you don't access any Azure specific features, there's no problem to deploying the web application project to an on-premise IIS.
If you use Azure-specific features or services from Azure, such as Azure SQL DB, you have to built an on-premise version. In my case it was simple as changing the connection string and the rest was done by Entity Framework, but you can use an IoC container, such as Unity, to change your implementation based on the environment you're running on. If the Azure environment is available (check through RoleEnvironment.IsAvailable) you resolve the Azure-specific implementation of some features and if not the on-premise implementation. In most cases that are just a few dependencies, for example if you use a worker role on Azure and a Windows Service on-premise.
I'm trying to understand if there is a way to make a web application run on the local computer(browser) without IIS.
My main objective is to transform my web application (that is on the internet) to a software that runs on the local computer without using the internet and without IIS.
My idea is to distributed my webapp between my colleagues and not forcing them to work online and not needing an internet connection.
I have a MVC web app with 3 pages and a couple of methods on the server side.
The idea of the application is to get proprieties from a form that I implemented on one of the pages of my web application and transform the proprieties on the client side to JSON and send it to the server, the server will generate XML file according to the JSON object and let the client download the XML file that were generated.
The flow of it:
1.The Client fill the form in my site.
2.The form become JSON object on the client side.
3.The JSON object that stored the properties of the form(filled by the client) is send to the server.
4.The server get the JSON object and generated XML document from it.
5.The client download the generated XML file.
Very simple web application.
I know that I can run HTML page by clicking it and the page will display on the browser but I need the server side to be working too to carry out actions.
So my question is : How can I make my web application run without internet ?
With the constrains:
No IIS required.
Working with .NET 4.0. (OWIN 2.0 - Not good)
No internet require.
No installation required to the computer ill pass this web app.
The server side code wont be expose when I send this application to my friends.
I read a couple of articles about OWIN, SingalR, Cassini and WCF but its all very vague...
If someone could provide me with a guide lines it will be very helpful.
Thanks a lot.
You can definitely self host a .NET web application using OWIN. Unfortunately documentation and information about it is vague and confusing at best. The fact that you're using MVC makes it somewhat easier as you may be able to directly use the self-host packages from Nuget for self hosting Web API. There may be similar packages for MVC.
I don't have recent experience but a Nuget search for "MVC Self Host" should yield some results.
Below is a link with an example. But the term you are looking for is definitely "self host". It can be done via a console window or (more complex) a windows service. It will likely use some form of OWIN but you can probably find some startup code to copy and paste into your project, usually in the form of a Startup.cs file.
http://www.c-sharpcorner.com/UploadFile/4b0136/working-with-owin-hosting-and-self-hosting-in-Asp-Net/
We have a web application developed in MVC 4 using Razor (.Net framework 4) and we have another web application developed using .net framework 2.0 without MVC.
We are sharing form authentication using machine key and we are sharing sessions between both application by changing the application name in global.asax.
When we run our project in local environment and in local IIS aswell both of them is working normally and all the multiple requests are processed and completed as usual.
But when we publish our project in IIS hosting server form authentication, session sharing and everything is working normally for a while but after sending multiple requests the MVC doesnot seem to process the request and its blocked so we are not able to send new requests.
Can any one please help us resolve this issue and explain where actually the problem is arising?
Thank you
