How to configure Application Insights with instrumentation keys from multiple environments in WCF?

If I set up my WCF project with an ApplicationInsights.config file as outlined in this Microsoft documentation, and data is logged to Application Insights (using the hardcoded instrumentation key) as expected.
Is there any way to specify instrumentation keys on a per-environment basis when using the ApplicationInsights.config file?
The config file looks like this:
<?xml version="1.0" encoding="utf-8"?>

My web.config contains the following:
<system.web>
<compilation debug="true" targetFramework="4.7.2" />
<httpRuntime targetFramework="4.7.2" />
<httpModules>
<add name="TelemetryCorrelationHttpModule" type="Microsoft.AspNet.TelemetryCorrelation.TelemetryCorrelationHttpModule, Microsoft.AspNet.TelemetryCorrelation" />

</httpModules>

This documentation suggests that I can set the instrumentation key in code (such as in an AppInitialize method as suggested by this answer), but it doesn't seem to work.
TelemetryConfiguration configuration = TelemetryConfiguration.CreateDefault();
configuration.InstrumentationKey = "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx";

While there appear to be some caveats to this solution (depending on your hosting strategy), it is sometimes possible to add a Global.asax, and use the Application_Start hook to inject your configuration (This answer assumes you're using config transforms).
For example:
using System;
namespace SomeWcfThing
{
public class Global : System.Web.HttpApplication
{
protected void Application_Start(object sender, EventArgs e)
{
Microsoft.ApplicationInsights.Extensibility.TelemetryConfiguration.Active.InstrumentationKey =
System.Configuration.ConfigurationManager.AppSettings["InstrumentationKey"];
}
}
}

The correct approach is to use TelemetryConfiguration.CreateDefault() method to load any config from disk, then set/change additional values on the generated configuration.
Once the TelemetryConfiguration instance is created pass it to the constructor of TelemetryClient to create the client and start logging.

How to set system.web compilation debug mode off via VSTS

I have this web.config file with the compilation option set as below:
<configuration>
...
<system.web>
<compilation debug="true" targetFramework="4.5" />
</system.web>
</configuration>
How to turn off the compilation's debug flag to false via VSTS's Build Definitions?
Update:
I'm deploying the system to Azure server by VSTS's release function.

You can use transformation to achieve what you want.
here is the documenation:
https://learn.microsoft.com/en-us/aspnet/web-forms/overview/deployment/visual-studio-web-deployment/web-config-transformations
Here is how your Web.debug.config file should look. You can also use web.release.config if you want to use transform in release mode.
<?xml version="1.0"?>
<!-- For more information on using Web.config transformation visit http://go.microsoft.com/fwlink/?LinkId=301874 -->
<configuration xmlns:xdt="http://schemas.microsoft.com/XML-Document-Transform">
<!--
In the example below, the "SetAttributes" transform will change the value of
"connectionString" to use "ReleaseSQLServer" only when the "Match" locator
finds an atrribute "name" that has a value of "MyDB".
<connectionStrings>
<add name="MyDB"
connectionString="Data Source=ReleaseSQLServer;Initial Catalog=MyReleaseDB;Integrated Security=True"
xdt:Transform="SetAttributes" xdt:Locator="Match(name)"/>
</connectionStrings>
-->
<system.web>
<compilation debug="false" xdt:Transform="Replace"/>
<!--
In the example below, the "Replace" transform will replace the entire
<customErrors> section of your Web.config file.
Note that because there is only one customErrors section under the
<system.web> node, there is no need to use the "xdt:Locator" attribute.
<customErrors defaultRedirect="GenericError.htm"
mode="RemoteOnly" xdt:Transform="Replace">
<error statusCode="500" redirect="InternalError.htm"/>
</customErrors>
-->
</system.web>
</configuration>

Web.config transform not transforming VS 2017

I have literally uncommented the boilerplate code and tried to publish to the file system to check if the "transform" works.
However, it does not transform the web.config file. I have look at the some articles and answers on here but cannot get it to work.
Things I tried:
Removing the namespace from the configuration node(complains about xdt missing)
Creating a new transform file(production)
Creating a new configuration(production)
Here is the web.Release.config:
<?xml version="1.0"?>
<!-- For more information on using Web.config transformation visit https://go.microsoft.com/fwlink/?LinkId=301874 -->
<configuration xmlns:xdt="http://schemas.microsoft.com/XML-Document-Transform">
<!--
In the example below, the "SetAttributes" transform will change the value of
"connectionString" to use "ReleaseSQLServer" only when the "Match" locator
finds an attribute "name" that has a value of "MyDB".
<connectionStrings>
<add name="MyDB"
connectionString="Data Source=ReleaseSQLServer;Initial Catalog=MyReleaseDB;Integrated Security=True"
xdt:Transform="SetAttributes" xdt:Locator="Match(name)"/>
</connectionStrings>
-->
<connectionStrings>
<add name="MyDB"
connectionString="Data Source=ReleaseSQLServer;Initial Catalog=MyReleaseDB;Integrated Security=True"
xdt:Transform="SetAttributes" xdt:Locator="Match(name)"/>
</connectionStrings>
<system.web>
<compilation xdt:Transform="RemoveAttributes(debug)" />
<!--
In the example below, the "Replace" transform will replace the entire
<customErrors> section of your Web.config file.
Note that because there is only one customErrors section under the
<system.web> node, there is no need to use the "xdt:Locator" attribute.
<customErrors defaultRedirect="GenericError.htm"
mode="RemoteOnly" xdt:Transform="Replace">
<error statusCode="500" redirect="InternalError.htm"/>
</customErrors>
-->
</system.web>
</configuration>
I get the following error:
No element in the source document matches '/configuration/connectionStrings/add[#name='MyDB']'
But as you can see it is present in the add node.
Any suggestions what to do? I am confused why it isn't working.
Edit:
web.config connection string
<connectionStrings>
<add name="DefaultConnection" connectionString="Data Source=.\SQLExpress;database=smartDB;Integrated Security=True" providerName="System.Data.SqlClient" />
</connectionStrings>

The value of the name attribute needs to match between your web.config and web.release.config, since you are specifying Match(name) in the transformation config.
In your web.config you have: name="DefaultConnection"
In your web.release.config: name="MyDB"

Glimpse works locally, not on remote server

After following all the guides, SO pages and troubleshooting pages I can find I'm finally out of ideas.
I've got Glimpse working fine on my local dev server, but when I deploy my ASP.net (MVC5) app to my remote server it doesn't work - at all. /glimpse.axd gives a 404 with both LocalPolicy and ControlCookiePolicy set to ignore, and with a custom security policy that returns On in all cases. My understanding is that with ControlCookiePolicy disabled, I shouldn't need to go to /glimpse.axd to enable it - but I'm not seeing the glimpse icon on the remote server either.
Even if I go to the remote server and browse localhost to /glimpse.axd I still get a 404.
My web.config looks like this:
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<configSections>
<section name="glimpse" type="Glimpse.Core.Configuration.Section, Glimpse.Core" />
</configSections>
<system.web>
<compilation debug="false" />
<httpRuntime targetFramework="4.5.1" relaxedUrlToFileSystemMapping="true" />
</system.web>
<system.webServer>
<modules runAllManagedModulesForAllRequests="true">
<remove name="FormsAuthentication" />
</modules>
<urlCompression doDynamicCompression="true" dynamicCompressionBeforeCache="false" />
</system.webServer>
<glimpse defaultRuntimePolicy="On" endpointBaseUri="~/Glimpse.axd">
<logging level="Trace" />
<runtimePolicies>
<ignoredTypes>
<add type="Glimpse.AspNet.Policy.LocalPolicy, Glimpse.AspNet" />
<add type="Glimpse.Core.Policy.ControlCookiePolicy, Glimpse.Core" />
</ignoredTypes>
</runtimePolicies>
</glimpse>
</configuration>
This is the version off the remote server (after transform). I've trimmed it a little to remove sections like appSettings.
My GlimpseSecurityPolicy.cs looks like this:
// Uncomment this class to provide custom runtime policy for Glimpse
using Glimpse.AspNet.Extensions;
using Glimpse.Core.Extensibility;
namespace RationalVote
{
public class GlimpseSecurityPolicy:IRuntimePolicy
{
public RuntimePolicy Execute(IRuntimePolicyContext policyContext)
{
return RuntimePolicy.On;
}
public RuntimeEvent ExecuteOn
{
// The RuntimeEvent.ExecuteResource is only needed in case you create a security policy
// Have a look at http://blog.getglimpse.com/2013/12/09/protect-glimpse-axd-with-your-custom-runtime-policy/ for more details
get { return RuntimeEvent.EndRequest | RuntimeEvent.ExecuteResource; }
}
}
}
The real one does an actual check, but I get the same issue with the policy above.
I cannot seem to find any trace output anywhere on the remote server, it is logging fine on my local machine.
I am deploying using the Visual Studio publish to web feature, and I've verified that the Glimpse.Core.dll is in the bin folder.
I can't see anything in the event log that is relevant.
I've also added <add namespace="Glimpse.Mvc.Html" /> to the namespaces block of the web.config in the views folder.
I tried putting #Html.GlimpseClient() in the _Layout.cshtml file just above </body> but this renders nothing.
Anybody got any ideas?

If the glimpse.axd is returning a 404 then this means the Glimpse resource handler is not registered.
If the web.config content you show above is not trimmed to much, then it is normal that Glimpse won't do much as the Glimpse HttpModule and the Glimpse HttpHandler are not registered in the system.web and/or the system.webserver sections like this
<system.web>
<httpModules>
<add name="Glimpse" type="Glimpse.AspNet.HttpModule, Glimpse.AspNet"/>
</httpModules>
<httpHandlers>
<add path="glimpse.axd" verb="GET" type="Glimpse.AspNet.HttpHandler, Glimpse.AspNet"/>
</httpHandlers>
</system.web>
<system.webServer>
<validation validateIntegratedModeConfiguration="false"/>
<modules>
<add name="Glimpse" type="Glimpse.AspNet.HttpModule, Glimpse.AspNet" preCondition="integratedMode"/>
</modules>
<handlers>
<add name="Glimpse" path="glimpse.axd" verb="GET" type="Glimpse.AspNet.HttpHandler, Glimpse.AspNet" preCondition="integratedMode" />
</handlers>
</system.webServer>
Maybe your transform removed to much from the local web.config?

Hardcoding into web.config in asp.net

Below specified is c# code and i am using asp.net with c#,The below code describes the date difference it will update the table after 2 months,
cmd3.CommandText = "update TrackingFaculty_det "
+ "SET Type=#Type WHERE "
+ "DATEDIFF(d,TrackingFaculty_det.LastUpdateDate,#Today)>60";
I need to hardcode the month value into web.config,so that if i want to change the date difference to three months or so on,so that in web.config if i make a change then the changes will occur in every c# pages where i have these lines of code.
My Web.Config is as below
<?xml version="1.0"?>
