Hi Madhu,
Once you deploy your App, The App will get deployed to the App web rather host web. That is reason you will not be able to find the app either in App part or webpart section of host web.

Provider Hosted app server error
Hello All,
I had created a provider hosted app with remote web app deployed in the same IIS server where sharepoint installed. I have used selfsigned certificates for trust. It works if i use visual studio IIS express to host remote web app.
But when I use Local IIS for hosting the web app, I am getting the following error. httpContext.Session[SPContextKey] is always null
Any help will be appreciated.

Any solution is appreciated.Hi,
To retrieve data from list in your provider-hosted app using SharePoint Client Object Model(CSOM), you can follow the links below for a quick start:

SharePoint Provider Hosted App that can update existing SharePoint Task List
Note: I am unable to take advantage of the Microsoft.SharePoint library directly. Adding a reference results in a 32bit/64bit library mismatch error.
I have to find a solution that uses only the Microsoft.SharePoint.Client extension.
I am looking for example code where provider-hosted SharePoint App loads a SharePoint Task List View that allows users to interact with the tasks.
So far I have only been able to programmatically create and then load the SharePoint tasks list, create and populate a DataTable object and set the datasource of a GridView object to that DataTable.
I am unable to trigger my method linked to my checkbox within the gridview.
Ideally I would like to just customize a Task View that already has this functionality.
Here is my default.aspx.cs code-behind file:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Data;

Uri redirectUrl;
switch (SharePointContextProvider.CheckRedirectionStatus(Context, out redirectUrl))
case RedirectionStatus.Ok:
return;
case RedirectionStatus.ShouldRedirect:
Response.Redirect(redirectUrl.AbsoluteUri, endResponse: true);
break;
case RedirectionStatus.CanNotRedirect:
Response.Write("An error occurred while processing your request.");
Response.End();
break;
protected void Page_Load(object sender, EventArgs e)
// The following code gets the client context and Title property by using TokenHelper.
// To access other properties, the app may need to request permissions on the host web.
var spContext = SharePointContextProvider.Current.GetSharePointContext(Context);
using (var clientContext = spContext.CreateUserClientContextForSPHost())
//clientContext.Load(clientContext.Web, web => web.Title);
//clientContext.ExecuteQuery();
//Response.Write(clientContext.Web.Title);
SP.ClientContext cc = new SP.ClientContext("http://server/sites/devapps");
SP.Web web = cc.Web;
SP.List list = web.Lists.GetByTitle("General Tasks");
SP.CamlQuery caml = new SP.CamlQuery();
Microsoft.SharePoint.Client.ListItemCollection items = list.GetItems(caml);
cc.Load<Microsoft.SharePoint.Client.List>(list);
cc.Load<Microsoft.SharePoint.Client.ListItemCollection>(items);
//try
//const int ColWidth = 40;
cc.ExecuteQuery();
DataTable dt = new DataTable();
dt.Columns.Add("Task Name", typeof(string));
dt.Columns.Add("ID", typeof(int));
foreach (Microsoft.SharePoint.Client.ListItem liTask in items)
DataRow dr = dt.NewRow();
dr["Task Name"] = liTask["Title"];
dr["ID"] = liTask["ID"];
//dr["chkTask"] = liTask["Checkmark"];
dt.Rows.Add(dr);
GridView1.DataSource = dt;
GridView1.DataBind();
protected void chkTask_CheckedChanged(object sender, EventArgs e)
//add code here to update Task Item by ID
Response.Write("checkbox event triggered");

http://www.net4geeks.com Who said I was a geek?Hi,
Please try to modify your code as below:
using (var clientContext = spContext.CreateUserClientContextForSPHost())
SP.Web web = clientContext.Web;
SP.List list = web.Lists.GetByTitle("General Tasks");
SP.CamlQuery caml = new SP.CamlQuery();
Microsoft.SharePoint.Client.ListItemCollection items = list.GetItems(caml);
clientContext.Load(items);
clientContext.ExecuteQuery();
If the code still not works, I suggest you debug the code or following the blog below to create a Provider-Hosted App for SharePoint and read list items from SharePoint list.

Any help appreciated!!
I'm getting this error: "The remote server returned an error: (401) unauthorised when I debug a provider-hosted app. I get the error on this line:
HttpWebResponse response = (HttpWebResponse)request.GetResponse();

I created a provider-hosted app with the intent to:
create a SharePoint list in the appweb
Use self-signed certificate, tokenhepler.cs and sharepointcontext.cs to retrieve current user context and access on SharePoint. (No changes were made to tokenhelper.cs and sharepointcontext.cs)
retrieve list items from the SharePoint list in a button click event handler on a default.aspx of the remote web
What happens:
The app is deployed successfully to the Dev site
The SharePoint feature is deployed and activated
The default.aspx page of the remote web loads
The error (see image) is returned on clicking of the button

Any ideas what I might be doing wrongHi ,
Use the below code
Public string GetAccessToken(){
string sharePointSiteUrlHost = Page.Request["SPHostUrl"].Tostring();
string AccessToken = tokenHelper.GetS2SAccessTokenWithWindowsIdentity(sharePointSiteUrlHost, Request.LogonUserIdentity);
return accessToken;
Than initialize the ClientCOntext with the below Method
private static ClientContext GetClientContextWithAccessTokenString(string targetUrl, object accessToken)
ClientContext clientContext = new ClientContext(targetUrl);
clientContext.AuthenticationMode = ClientAuthenticationMode.Anonymous;
clientContext.FormDigestHandlingEnabled = false;
clientContext.ExecutingWebRequest +=
delegate(object oSender, WebRequestEventArgs webRequestEventArgs)
webRequestEventArgs.WebRequestExecutor.WebRequest.UserAgent = "Mozilla/5.0 (compatible; MSIE 9.0; Windows NT 6.1; WOW64; Trident/5.0)";
webRequestEventArgs.WebRequestExecutor.RequestHeaders["Authorization"] =
"Bearer " + accessToken;
return clientContext;
use this clientCOntext and it will work.
Do not use

We have already added the certificate used for the SharePoint site and the provider hosted app in the SharePoint central admin trusts.
Any idea's how can I resolve this issue?Hi,
According to your post, my understanding is that you failed to access provider host app using https.
The reason for this is that SharePoint implements its own certificate validation policy to override .NET certificate validation.
Fix is to setup a trust between SharePoint and the server requiring certificate validation.
For more information, you can refer to:
http://blogs.technet.com/b/sharepointdevelopersupport/archive/2013/06/13/could-not-establish-trust-relationship-for-ssl-tls-secure-channel.aspx

SharePoint Provided host app - The client webpart suddenly got removed
I have SharePoint provided host app and it contains one client webpart. I have added that webpart one of the pages in site after deploying the app in site.
Issue we are facing now:
The client webpart suddenly got removed from the page and no one has modified the page to delete the webpart.
And it is not listing in App parts while trying to add the webpart to page.
Is there any way to trace this issue?
Thanks,
Surya
Thanks, SuryaHi Surya,
Please try to restore page history per the article below:
http://rules.ssw.com.au/ITAndNetworking/Rules-to-Better-Sharepoint-for-End-Users/Pages/VersionHistory.aspx
If you need to dig out who changed it, you may check ULS log or audit log if you have audit feature enabled.

Error with Provider Hosted App on Edit Form of a list item
We have an error on the Edit Form of one of our pages.
We have developed a SharePoint Online Provider Hosted app which replaces the standard edit form of a list item and has some further events behind the save button. Since this is rather new territory for us, we're using a roundabout way of achieving this by
using a script editor web part to display an iFrame of our app. That way we can pass the Url through to our app and retrieve query strings from them.
Our issue comes quite intermittently in that we sometimes get a "web page cannot be found" error or sometimes a "resource cannot be found" error, however, when we load another app on the site (from the same app project, but using an app
part), then go back to the Edit Form, the information in the iFrame suddenly renders.
Any ideas on what might be causing this issue at all? Ideally, we should be rendering the app to the Edit Form is the proper manner, rather than scripting an iFrame that points to out app in Azure. Would this be the cause of the problem?
Thanks
TomHi thumper, if you have access to InfoPath, you can add the form to a page using the InfoPath web part. Otherwise, use SP Designer with instructions below:

Unable to deploy the provider hosted app on sharepoint server !!!
Hello,
I have simply created the provider hosted app by assigning the issuer ID !
Now, the SharePoint version of the app project is set as SharePoint Online.
However, when I deploy this project to SharePoint site, it shows following error :
Unknown SharePoint version: 16.0
In order to resolve this I changed the SharePoint version as SharePoint 2013
of the app project.
Though , I am getting following error on deployment:
The target version of the SharePoint site is 15.0.4569.1000, which is lower than the minimum supported SharePoint version of the app. To fix this, go to the SharePoint tab on the app for SharePoint project’s properties page, and change the Target
SharePoint Version property to the version of the SharePoint site or lower.
Would you please let me know how can I resolve this deployment error ?
Note : I am using MVC web Application template for web project
Thank you in advance.
Kind Regards,
Dipti ChhatrapatiNot sure, but this is straight.
Project type - apps for sharepoint --> Enter URL --> select type as provider hosted app --> MVC --> Authentication Option.
Now when publishing the project - SP App to SharePoint/Office Store and web portion to any web server ( i generally do it in Azure).

Hi,
I have a customer running a provider hosted app and in Sharepoint 2013. Things have been working fine but recently they keep experiencing an issue where the all the app parts on the page show the following error message. Does anyone have an idea what
could be causing this problem and how I can fix it? The Sharepoint site and provider hosted app site are running on a Server 2008 R2 box with IIS 7.5.
Server Error in '/Test.Sharepoint.App' Application.

Impreza Software DevelopmentHi GuYumming,
I have checked the Sharepoint site using Fiddler and my X-SharePointHealthScore stays consistently on 1, I have even refreshed the site and had the "(429) Too Many Requests" error happen right in front of me whilst Fiddler is running and when I look at the
200 response for the Sharepoint site it is still showing "X-SharePointHealthScore: 1".
I assume because of this I do not need to make any of the changes suggested in your article above?
I have also been through the ULS logs and found the following 3 log entries that appear to relate to the issue but they do not really mean much to me so I am hoping that you can help:
Begin CSOM Request ManagedThreadId=59, NativeThreadId=12476

How to get the current user name in Provider hosted app using appOnlyAccessToken
Hi,
Please help me, how to get the HostWeb UserName in Provider Hosted App
i have Provider hosted App, and Anonymous Authentication is enabled on AppWeb, using appOnlyAccessToken
Below code does not return current user who Log in in hostweb, it is returning
SharePoint App (app@sharepoint)
Web web = clientContext.Web;
clientContext.Load(web);
clientContext.ExecuteQuery();
clientContext.Load(web.CurrentUser);
clientContext.ExecuteQuery();
clientContext.Web.CurrentUser.LoginName;
Below code gives a blank name when Anonymous Authentication is enabled, if Anonymous Authentication is disabled
app prompts for credentials
HttpContext.Current.User.Identity.Name
Thanks
RamHi,
Since you are using a provider Hosted app if you want to get the current logged in name than do not use AppOnlyAccessToken else use AccessToken which is App + user Context AccessToken.
then
Web web = clientContext.Web;
clientContext.Load(web);
clientContext.ExecuteQuery();
clientContext.Load(web.CurrentUser);
clientContext.ExecuteQuery();
clientContext.Web.CurrentUser.LoginName;will return proper user Name.
HttpContext.Current.User.Identity.Name will never return the user as this object is related to IIS server of your App Server not sharepoint.you should set this as Anonymous in case of provider hosted app.you can download the below sample which uses the AccessToken which has user name in it.https://code.msdn.microsoft.com/Working-provider-hosted-8fdf2d95

My country is not listed in the Mac app store and iTunes?
My country is not listed in the Mac app store or iTunes. and yes ive tried putting in false information like 'I live in the USA, NY' but whenever i try buying something it says "Your credit card information does not match your banks records, Please enter a US billing card.. and such. Because of this i have no choice but to use what you call 'pirated' applications. Any help fellow mac users?
Sorry, but it's Apple's policy...
"Although you can browse the iTunes Store in any country without being signed in, you can only purchase content from the iTunes Store for your own country. This is enforced via the billing address associated with your credit card or other payment method that you use with the iTunes Store, rather than your actual geographic location."
