Windows Phone SDK7.1 on windows 7 sp1- compatibility issue

hi All,

Since I am back to work and hence trying to explore all new. for the same I wanted to explore Windows Phone, hence I saved the vm_web2.exe on hard disk and was trying to install.

every time I was getting error - compatibility error goto http://go.microsoft.com/fwlink/?LinkId=143397.

I tried -

Unsitall Visual studio 2010 professional.
right click on vm_web.exe, properties ->CompatibilityTab.
played with regirtry Entries

Nothing worked, finally I landed to download page again and instead of saving to hard disk , I installed from there and every thing is working fine.

what a fix :d

Save your time and try this as well.

new SPSITE("") error - could find web application at URL

hi All,

I am back Almost after a year :)
When creating console application for sharepoint , today again I got good old error saying could not find the web application. recalled all the thread and now noting down the solution -

Project properties -> target .net framework should be 3.5
and Target CPU must be "Any" from "Build Tab".

Enjoy coding :)

Debugging Sync Framework / DbApplyChangeFailedEventArgs

hi,

Lastly I was busy working in sync, basically sync between on-premise sql server and Azure server. for this I created -

manual code as posted by Liam http://blogs.msdn.com/b/sync/archive/2010/08/31/sql-server-to-sql-azure-synchronization-using-sync-framework-2-1.aspx
later used CTP2 for data sync.https://datasync.azure.com/

after good amount of testing and all, I started getting error in sync, and was completely unable to get details about the error.
Liam code does not provide details about the error, just the boolean flag, whether done or not. same with CTP2, and I need to know the details about error.
Thanks to http://softarchitect.wordpress.com/2010/10/03/software-architecture-sync-data-between-offline-disconnected-databases-sync-framework/ I was able to get the exact Error and then little googling around 'DbApplyChangeFailedEventArgs. http://msdn.microsoft.com/en-us/library/microsoft.synchronization.data.dbapplychangefailedeventargs.aspx
helped me crack the error.
So finally the code which worked out for debugging is

public static void Sync(System.IO.StreamWriter file)

{

SqlConnection sqlServerConn = new SqlConnection(sqllocalConnectionString);

SqlConnection sqlAzureConn = new SqlConnection(sqlazureConnectionString);

try

{

SyncOrchestrator orch = new SyncOrchestrator

{

LocalProvider = new SqlSyncProvider(scopeName, sqlAzureConn),

RemoteProvider = new SqlSyncProvider(scopeName, sqlServerConn),

Direction = SyncDirectionOrder.UploadAndDownload

};

((SqlSyncProvider)orch.LocalProvider).ApplyChangeFailed += new EventHandler(Program_ApplyChangeFailed);

file.WriteLine("Starting Sync:: " + DateTime.Now);

}

catch (Exception ex)

{

file.WriteLine("Error in SYNC:" + ex.Message);

file.WriteLine("Error in Sync stack trace Message:" + ex.StackTrace);

}

finally

{

sqlAzureConn.Close();

sqlServerConn.Close();

}

}

static void Program_ApplyChangeFailed(object sender, DbApplyChangeFailedEventArgs e)

{

// display conflict type

// display error message

Console.WriteLine(e.Conflict.Type);

DataTable conflictingRemoteChange = e.Conflict.RemoteChange;

DataTable conflictingLocalChange = e.Conflict.LocalChange;

int remoteColumnCount = conflictingRemoteChange.Columns.Count;

Console.WriteLine(String.Empty);

Console.WriteLine(String.Empty);

Console.WriteLine(String.Empty);

Console.Write("
");

//Display the remote row from _tracking table.

for (int i = 0; i < remoteColumnCount; i++)

{

Console.Write(conflictingRemoteChange.Rows[0][i] + "
");

}

//Ask for a conflict resolution option.

Console.WriteLine(String.Empty);

Console.WriteLine(String.Empty);

Console.WriteLine("Enter a resolution option for this conflict:");

string conflictResolution = Console.ReadLine();

conflictResolution.ToUpper();

if (conflictResolution == "A")

{

e.Action = ApplyAction.Continue;

}

else if (conflictResolution == "B")

{

e.Action = ApplyAction.RetryWithForceWrite;

}

else

{

Console.WriteLine(String.Empty);

Console.WriteLine("Not a valid resolution option.");

}

Console.WriteLine(e.Error);

}

MIgration to Azure - Part 3 HelloWorld

How to - ADFS with HelloWorld

Create one cloud project and add one web role. The web role will contain very
simple 'HelloWorld'.
Upload one .pfx certificate to http://windows.Azure.com
Add certificate and STS reference to project -
http://claimsid.codeplex.com/

Adding certificate and STS reference will make some changes in web.config and in
service configuration file -

Service Configuration file

Web.config File

<system.webServer>
<modules runAllManagedModulesForAllRequests="true">
<add name="ClaimsPrincipalHttpModule" type="Microsoft.IdentityModel.Web.ClaimsPrincipalHttpModule, Microsoft.IdentityModel, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" preCondition="managedHandler" />
<add name="WSFederationAuthenticationModule" type="Microsoft.IdentityModel.Web.WSFederationAuthenticationModule, Microsoft.IdentityModel, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" preCondition="managedHandler" />
<add name="SessionAuthenticationModule" type="Microsoft.IdentityModel.Web.SessionAuthenticationModule, Microsoft.IdentityModel, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" preCondition="managedHandler" />
</modules>
</system.webServer>

And

<microsoft.identityModel>
<service>

<serviceCertificate><certificateReference x509FindType="FindByThumbprint" findValue="A97379892B76D70BC4C453C5F4AAC00428DB7E83" storeLocation="LocalMachine" storeName="My" /></serviceCertificate>
<applicationService>
<claimTypeRequired>

<claimType type="http://schemas.xmlsoap.org/ws/2005/05/identity/claims/name" optional="true" />
<claimType type="http://schemas.microsoft.com/ws/2008/06/identity/claims/role" optional="true" />



















</claimTypeRequired>
</applicationService>


<audienceUris>
<add value="https://ptswebdev.cloudapp.net/" />
</audienceUris>
<federatedAuthentication>
<wsFederation passiveRedirectEnabled="true" issuer="https://corp.sts.microsoft.com/adfs/ls/" realm="https://ptswebdev.cloudapp.net" requireHttps="true" />
<cookieHandler requireSsl="true" />
</federatedAuthentication>
<issuerNameRegistry type="Microsoft.IdentityModel.Tokens.ConfigurationBasedIssuerNameRegistry, Microsoft.IdentityModel, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35">
<trustedIssuers>
<add thumbprint="41DFA100BE890909B3ED5E93761F8174680EACD6" name="urn:federation:MSFT" />
</trustedIssuers>
</issuerNameRegistry>
</service>
</microsoft.identityModel>

Now Open Global.asax -

Add following

void Application_Start(object sender, EventArgs e)

{

// Code that runs on application startup
FederatedAuthentication.ServiceConfigurationCreated += new EventHandler(FederatedAuthentication_ServiceConfigurationCreated);
FederatedAuthentication.WSFederationAuthenticationModule.RedirectingToIdentityProvider
+= new EventHandler(WSFederationAuthenticationModule_RedirectingToIdentityProvider);

}

void WSFederationAuthenticationModule_RedirectingToIdentityProvider(object sender,
RedirectingToIdentityProviderEventArgs e)

{

Uri reqUrl = Request.Url; StringBuilder wreply = new StringBuilder();
wreply.Append(reqUrl.Scheme); // e.g. "http" wreply.Append("://");
wreply.Append(Request.Headers["Host"] ?? reqUrl.Authority);
wreply.Append(Request.ApplicationPath); if
(!Request.ApplicationPath.EndsWith("/")) { wreply.Append("/"); }
e.SignInRequestMessage.Reply = wreply.ToString();

}

void FederatedAuthentication_ServiceConfigurationCreated(object sender,
Microsoft.IdentityModel.Web.Configuration.ServiceConfigurationCreatedEventArgs
e)

{

List sessionTransforms = new List( new
CookieTransform[] { new DeflateCookieTransform(), new
RsaEncryptionCookieTransform( e.ServiceConfiguration.ServiceCertificate), new
RsaSignatureCookieTransform( e.ServiceConfiguration.ServiceCertificate) });
SessionSecurityTokenHandler sessionHandler = new
SessionSecurityTokenHandler(sessionTransforms.AsReadOnly());
e.ServiceConfiguration.SecurityTokenHandlers.AddOrReplace( sessionHandler);

}

Open Default.aspx -

On Page load or any event Add following -

protected void Page_Load(object sender, EventArgs e)

{

try

{

IClaimsIdentity ici = Thread.CurrentPrincipal.Identity as IClaimsIdentity; foreach
(Claim c in ici.Claims) Response.Write(c.ClaimType + " - " + c.Value + "

");

}

catch (Exception ex)

{ Response.Write(ex.ToString()); }

}

You are done :)) Bingoo

I didn't added much for adding STS and ceritifcate as it is widely
avaiable on net.
