I deployed the web service, I created. But, I having an error when I tested it on the server. Anyone can help me about this issue?
Here's the error:

Regex pattern to read an Web.config

I need your valuable help, in reading a connection string value using regex -
Idea is to read the pattern using saltstack state file, and replace with VSTS variable.
Could you please help , how can I read the value ?

Below is my salt state file :
Thanks,
I use a Powershell script to replace the values of the connection string in the web.config.
After I "catch" the connection string I run this code:
$dbServer = [regex]::Match($connection, '(?i)data source=([^;]+)').Groups[1].Value
$newConnection = $connection.Replace($dbServer+';', $newSqlServerName+';')
$dbName = [regex]::Match($connection, '(?i)initial catalog=([^;]+)').Groups[1].Value
$newConnection = $newConnection.Replace($dbName+';', $newDbName+';')
So the Regex is:
For Data Source: (?i)data source=([^;]+)
For Initial Catalog: (?i)initial catalog=([^;]+)
For User name: (?i)user id=([^;]+)
For Password: (?i)password=([^;]+)

ASP proper config to allow CORS in a asmx webservice for POST requests

I´m trying to setup a server capable to handle CORS, but also capable to return the response in json format.
Tried with various config schemes, but no luck.
I need to do my Ajax requests via POST. With my actual config i´m able to do requests via GET, but currently my response always is encapsulated in XML format.
As stated in ResponseFormat.Json returns xml , my requests must be 'application/json' but when I try to do it in this way I'm receiving a preflight message (Response for preflight has invalid HTTP status code 404).
My web.config (allowing CORS via GET) currently is:

I´m using iron-polymer for the Ajax-requests and combined various content-types. Currently i´m getting my data via GET using 'content-type="application/x-www-form-urlencoded; charset=UTF-8" handle-as="document"'.
I´m having difficulties to process the response due such XML encapsulation. Below are two examples of received responses. How to extract the contents ?

VS2012 Unit Test Project and MSFT Ent Lib 5.0

I have the following (but very annoying) problem with this particular type project and Ent Lib 5.0.
The reason I am saying it pertains to the fact that it is a Unit Test project related is that the same code/configuration work fine from a Console Application.
Here is the code:
ICacheManager cm = CacheFactory.GetCacheManager("TestCacheManager");
cm.Add("max", 1);
Here is the config:
<configuration>
<configSections>
<section name="dataConfiguration" type="Microsoft.Practices.EnterpriseLibrary.Data.Configuration.DatabaseSettings, Microsoft.Practices.EnterpriseLibrary.Data, Version=5.0.414.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" requirePermission="true" />
<section name="cachingConfiguration" type="Microsoft.Practices.EnterpriseLibrary.Caching.Configuration.CacheManagerSettings, Microsoft.Practices.EnterpriseLibrary.Caching, Version=5.0.414.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" requirePermission="true" />
</configSections>
<dataConfiguration defaultDatabase="Caching" />
<connectionStrings>
<add name="Caching" connectionString="Data Source=.;Initial Catalog=Caching;Integrated Security=True"
providerName="System.Data.SqlClient" />
</connectionStrings>
<cachingConfiguration defaultCacheManager="TestCacheManager">
<cacheManagers>
<add name="TestCacheManager" type="Microsoft.Practices.EnterpriseLibrary.Caching.CacheManager, Microsoft.Practices.EnterpriseLibrary.Caching, Version=5.0.414.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"

numberToRemoveWhenScavenging="10" backingStoreName="TestStore" />
</cacheManagers>
<backingStores>
<add name="TestStore" type="Microsoft.Practices.EnterpriseLibrary.Caching.Database.DataBackingStore, Microsoft.Practices.EnterpriseLibrary.Caching.Database, Version=5.0.414.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"

name="NullBackingStore" />
</backingStores>
</cachingConfiguration>
</configuration>
And then finally the exception that I only get in the Unit Test Project:
Activation error occured while trying to get instance of type ICacheManager, key "TestCacheManager"

Try adding this to your handlers section in the web.config

How do you configure Elmah to tweet error messages?

I read that Elmah can tweet error messages so I tried to set it up, but could not get it to work. I am able to get it to save the errors into a database and email me the error, but the tweet doesn't seem to work.
Here is my configuration:
<configSections>
<sectionGroup name="elmah">
<section name="security" requirePermission="false" type="Elmah.SecuritySectionHandler, Elmah"/>
<section name="errorLog" requirePermission="false" type="Elmah.ErrorLogSectionHandler, Elmah" />
<section name="errorMail" requirePermission="false" type="Elmah.ErrorMailSectionHandler, Elmah" />
<section name="errorFilter" requirePermission="false" type="Elmah.ErrorFilterSectionHandler, Elmah"/>
<section name="errorTweet" requirePermission="false" type="Elmah.ErrorTweetSectionHandler, Elmah"/>
</sectionGroup>
</configSections>
<elmah>
<security allowRemoteAccess="1" />
<errorLog type="Elmah.SqlServerCompactErrorLog, Elmah" connectionStringName="LoggingDB" />
<errorTweet
userName="twitter_username"
password="twitter_password" statusFormat="{Message}" />
</elmah>
<system.webServer>
<modules>
<add name="ErrorLog" type="Elmah.ErrorLogModule, Elmah" preCondition="managedHandler" />
<add name="ErrorFilter" type="Elmah.ErrorFilterModule, Elmah" preCondition="managedHandler" />
<add name="ErrorMail" type="Elmah.ErrorMailModule, Elmah" preCondition="managedHandler" />
<add name="ErrorTweet" type="Elmah.ErrorTweetModule, Elmah" preCondition="managedHandler" />
</modules>
<handlers>
<add name="Elmah" path="elmah.axd" verb="POST,GET,HEAD" type="Elmah.ErrorLogPageFactory, Elmah" preCondition="integratedMode" />
</handlers>
</system.webServer>
No errors occur, the tweet just does not appear even though it's logged in the database and emailed.
See the ErrorHowling wiki on the project's site for some background and information on ErrorTweetModule and its use.
