Why this DataProtectionProvider Error Occurs

I am testing the config data protection using DataProtectionProvider class. The test code works in one way, but failed in another way.
TEST ENVIRONMENT:
App type: ASP.NET 6 console app with c#
Package: Microsoft.AspNetCore.DataProtection.Extensions 6.0.3
IDE: VS 2022
Test Project: ProtectData
PROBLEM DESCRIPTION:
In DataProtector class has 3 methods (see test code #1).
The TestProtector method is for initial testing. It encrypt and decrypt data in the same method. It works without any problem
In methods EncryptData and DecryptData handle the process in 2 separate steps. When running tests with these methods, the exception occurs in the DecryptData method on the statement: decrypted = protector.Unprotect(encryptedData); The exception info is shown in following screen shot.
The tests were run using the program.main method (see test code $2)
QUESTION:
When comparing the code in "TestProtector" method with code in these 2 method, they all handle the process in the same way with same key. Why does one method works perfectly and the "two-step" always fail? It really puzzles me. I'll appreciate any help or suggestions for troubleshooting.
TEST CODE

Console.WriteLine($"UnprotectPayload:\n{decrypted}\n");
//show verification result
Console.WriteLine($"Verify result:\n{(inputText == decrypted ? true : false)}");
}
catch(Exception ex)
{
Console.WriteLine("Error:", ex);
}
}
}
}
---- Test code #2 (program main)
namespace ProtectData
{
public class Program
{
static void Main()
{
string testType = "two_step";
RunTest(testType);
Console.WriteLine();
Console.WriteLine("Press any key...");
Console.ReadKey();
}
static void RunTest(string testType)
{
switch ( testType.ToLower())
{
case "simple":
DataProtector.TestProtector();
break;
case "two_step":
string inputData = "DataSource=localhost, database=testdb, userID=appuser, password=topsecret";
Console.WriteLine($"inputData:\n{inputData}\n");
string protectedData = DataProtector.EncryptData(inputData);
Console.WriteLine($"protectedData:\n{protectedData}\n");
string outputData = DataProtector.DecryptData(protectedData);
Console.WriteLine($"outputData:\n{outputData}\n");
bool verify = inputData == outputData;
Console.WriteLine($"verified: {verify}");
break;
}
}
}
}

I was able to fix the problem using examples provided in following online doc:

C# - Visual Studio - 'object' does not contain a definition for 'ExecuteQuery'

I am trying to add code to an existing project that will check for existence of a device in SCCM and delete it if it does exist. I seem to be missing something, in that particular block of code.

Well - after a few days of searching, I FINALLY figured out the issue.
The entire block of code at the end, was not necessary. The issue was that there were missing assembly references and using statements in the code. Specifically:
using Microsoft.ConfigurationManagement.ManagementProvider;
using Microsoft.ConfigurationManagement.ManagementProvider.WqlQueryEngine;
The corresponding DLLs also needed to be added to the project as references.
I hope this helps someone who runs into similar issues and is not versed in C# coding. I myself am only versed in PowerShell, so figuring this out took a lot of work for me. Thanks.

You create a custom "connection" object:
WqlConnectionManager connection = new WqlConnectionManager(namedValues);
Then call a method on one of its properties:
connection.QueryProcessor.ExecuteQuery("...")
But what is that QueryProcessor property?...
public object QueryProcessor { get; internal set; }
It's an object. As the error states, object doesn't have a method called ExecuteQuery. (It doesn't have very many methods or properties at all, really.)
I can't really tell from this code (maybe I'm missing something?) what specific type you're expecting QueryProcessor to be, but it should definitely be something more specific than object. Something analogous to a SQLCommand object, perhaps? Essentially, whatever type would have that ExecuteQuery method.
If there's a compelling reason in the existing codebase for this to be of type object, you'd need to determine what that reason is. There seems to be a lot of use of object here, which smells of some bad design choices from before you got there.

Hadoop task is cancelled due to task timeout

I am writing a C# mapreduce program that runs on the cluster. The system returns an error of
System.Threading.Tasks.Task
The task is cancelled after a timeout of 32 milliseconds. The data is pretty huge .I even changed the data size to check but the error still occurs, so I am assuming it is not due to the data size.
Is there a way to change the task timeout of 32 milliseconds.
I am using Azure, Visual studio 2013 and a cluster with 4 nodes.
The system aggregate exception occured in mscorlib.dll

some delay processing message in MessageInterceptor

Sorry, my english is not quite well.
I'm new in programming world and tried to create an application using messageinterceptor on windows mobile 6.5.3.
but when i send text message to my phone, there was delay about 30 seconds or more before the message is processed, either text message which contain keywords or not.
I read several sources before deciding to try to make my own application, but these source are using Windows Form (GUI), instead of using Windows Form, i make it run in console mode.
here is the code:
using System;
using System.Linq;
using System.Collections.Generic;
using System.Text;
using Microsoft.WindowsMobile.PocketOutlook.MessageInterception;
using Microsoft.WindowsMobile.PocketOutlook;
using Microsoft.WindowsMobile;
using System.IO;
namespace PenerimaPesan
{
class Program
{
static void Main(string[] args)
{
string applicationID;
applicationID = "tracker";
MessageInterceptor pesanmasuk = null;
pesanmasuk = new MessageInterceptor();
pesanmasuk.EnableApplicationLauncher(applicationID);
if (MessageInterceptor.IsApplicationLauncherEnabled(applicationID))
{
string keyword;
StreamReader key = new StreamReader(#"\Windows\conf.txt");
string data = key.ReadToEnd();
string[] isi = data.Split(new char[] { '\n' });
keyword = isi[1];
keyword = keyword.Replace(" ", "");
pesanmasuk = new MessageInterceptor(InterceptionAction.NotifyAndDelete, false);
pesanmasuk.MessageCondition = new MessageCondition(MessageProperty.Body, MessagePropertyComparisonType.StartsWith, ""+keyword);
pesanmasuk.MessageReceived += new MessageInterceptorEventHandler(pesanmasuk_MessageReceived);
}
}
static void pesanmasuk_MessageReceived(object sender, MessageInterceptorEventArgs e)
{
SmsMessage pesan = e.Message as SmsMessage;
if (pesan != null)
{
string perintah;
string[] command = pesan.Body.Split(new char[] { '.' });
perintah = command[1];
if (perintah == "helo")
/*do some Stuff*/
}
}
}

I've never used MessageInterceptor, so I decided I'd try to implement this code in my application. To test it, I renamed Main to Main2, then cleaned it up to match "my style".
Anyway, I ran into errors when I tried wrapping the MessageInterceptor in a using block - not because MessageInterceptor does not implement IDispose, but because you have declared a new instance of it.
Take a look at this snippet of your code:
MessageInterceptor pesanmasuk = new MessageInterceptor();
pesanmasuk.EnableApplicationLauncher(applicationID);
if (MessageInterceptor.IsApplicationLauncherEnabled(applicationID)) {
string keyword;
StreamReader key = new StreamReader(#"\Windows\conf.txt");
string data = key.ReadToEnd();
string[] isi = data.Split(new char[] { '\n' });
keyword = isi[1];
keyword = keyword.Replace(" ", "");
pesanmasuk = new MessageInterceptor(InterceptionAction.NotifyAndDelete, false);
OK, right there. Stop. You created a new instance of your pesanmasuk variable, set Properties, did some checking, worked with data from a text file, then...
Created a new instance of your pesanmasuk variable.
All of your previous settings are now whipped out.
I'm guessing your first instance is running and perhaps the second instance has to wait for the first instance to time out before it can be created.
At this point, I'm interested to learn just how to use this MessageInterceptor on MSDN, looked into the example there, and came up with this [untested] version:
static void Main2(string[] args) {
const string stackOverflowUrl = #"http://stackoverflow.com/questions/8520488/some-delay-processing-message-in-messageinterceptor";
string empty = String.Empty;
StreamReader key = new StreamReader(#"\Windows\conf.txt");
string data = key.ReadToEnd();
string[] lines = data.Split(new char[] { '\n' });
string keyword = lines[1].Replace(" ", empty);
string applicationID = "trackingApplication";
using (MessageInterceptor smsInterceptor = new MessageInterceptor(applicationID, false)) {
smsInterceptor.InterceptionAction = InterceptionAction.NotifyAndDelete;
smsInterceptor.MessageCondition = new MessageCondition(MessageProperty.Body, MessagePropertyComparisonType.StartsWith, empty + keyword);
smsInterceptor.MessageReceived += new MessageInterceptorEventHandler(Intercept_MessageReceived);
smsInterceptor.EnableApplicationLauncher(applicationID);
if (MessageInterceptor.IsApplicationLauncherEnabled(applicationID)) {
// Here, you'd need to launch your Form1 or enable some timer,
// otherwise the code will return immediately and the MessageInterceptor
// instance will be disposed of.
}
smsInterceptor.MessageReceived -= MessageInterceptorEventHandler;
}
}
static void Intercept_MessageReceived(object sender, MessageInterceptorEventArgs e) {
SmsMessage newMessage = e.Message as SmsMessage;
if (newMessage != null) {
Console.WriteLine("From: {0}", newMessage.From.Address);
Console.WriteLine("Body: {0}", newMessage.Body);
string[] command = newMessage.Body.Split(new char[] { '.' });
string line = command[1];
if (line == "helo") {
/*do some Stuff*/
}
}
}
I hope this helps, but keep in mind that I've never actually used this control and my code has not been tested.

How do I access the CodeDomProvider from a class inheriting from Microsoft.VisualStudio.TextTemplating.VSHost.BaseCodeGeneratorWithSite?

Does anyone know how to get a CodeDomProvider in the new Microsoft.VisualStudio.TextTemplating.VSHost.BaseCodeGeneratorWithSite from the Visual Studio 2010 SDK? I used to get access to it just by in mere inheritance of the class Microsoft.CustomTool.BaseCodeGeneratorWithSite, but now with this new class it is not there. I see a GlobalServiceProvider and a SiteServiceProvider but I can't find any example on how to use them.
Microsoft.VisualStudio.TextTemplating.VSHost.BaseCodeGeneratorWithSite:
http://msdn.microsoft.com/en-us/library/bb932625.aspx
I was to do this:
public class Generator : Microsoft.VisualStudio.TextTemplating.VSHost.BaseCodeGeneratorWithSite {
public override string GetDefaultExtension() {
// GetDefaultExtension IS ALSO NOT ACCESSIBLE...
return this.InputFilePath.Substring(this.InputFilePath.LastIndexOf(".")) + ".designer" + base.GetDefaultExtension();
}
// This method is being called every time the attached xml is saved.
protected override byte[] GenerateCode(string inputFileName, string inputFileContent) {
try {
// Try to generate the wrapper file.
return GenerateSourceCode(inputFileName);
} catch (Exception ex) {
// In case of a faliure - print the exception
// as a comment in the source code.
return GenerateExceptionCode(ex);
}
}
public byte[] GenerateSourceCode(string inputFileName) {
Dictionary<string, CodeCompileUnit> oCodeUnits;
// THIS IS WHERE CodeProvider IS NOT ACCESSIBLE
CodeDomProvider oCodeDomProvider = this.CodeProvider;
string[] aCode = new MyCustomAPI.GenerateCode(inputFileName, ref oCodeDomProvider);
return Encoding.ASCII.GetBytes(String.Join(#"
", aCode));
}
private byte[] GenerateExceptionCode(Exception ex) {
CodeCompileUnit oCode = new CodeCompileUnit();
CodeNamespace oNamespace = new CodeNamespace("System");
oNamespace.Comments.Add(new CodeCommentStatement(MyCustomAPI.Print(ex)));
oCode.Namespaces.Add(oNamespace);
string sCode = null;
using (StringWriter oSW = new StringWriter()) {
using (IndentedTextWriter oITW = new IndentedTextWriter(oSW)) {
this.CodeProvider.GenerateCodeFromCompileUnit(oCode, oITW, null);
sCode = oSW.ToString();
}
}
return Encoding.ASCII.GetBytes(sCode );
}
}
Thanks for your help!

You can access the CodeDomProvider via the SiteServiceProvider by asking for the SVSMDCodeDomProvider service.
Something along the lines of:
IVSMDCodeDomProvider provider = SiteServiceProvider.
GetService(typeof(SVSMDCodeDomProvider)) as IVSMDCodeDomProvider;
if (provider != null)
{
codeDomProvider = provider.CodeDomProvider as CodeDomProvider;
}
The SiteServiceProvider is the limited scope service provider exposed by the site of a SingleFileGenerator, whereas the GlobalServiceProvider is VS' main service provider that you can ask for any globally-scoped interface.
Hope this helps.
