Property of an AppModel application not getting updated in SCCM

I'm trying to update SDMPackageXML property of an AppModel application through C# code. SDMPackageXML is an XML property. I've to update only one node named AutoInstall in the
SDMPackageXML XML property. Here is my code:
ObjectGetOptions opt = new ObjectGetOptions(null, System.TimeSpan.MaxValue, true);
var path = new ManagementPath("SMS_Application.CI_ID=16777568");
ManagementObject obj = new ManagementObject(scope, path, opt);
obj.Get();
foreach (PropertyData property in obj.Properties)
{
if (property.Name == "SDMPackageXML")
{
//change the property value. Set AutoInstall to true
XmlDocument xml = new XmlDocument();
xml.LoadXml(property.Value.ToString());
var autoInstallTag = xml.GetElementsByTagName("AutoInstall");
autoInstallTag[0].InnerText = "false";
property.Value = xml.OuterXml;
}
}
obj.Put();
The problem is that obj.Put(); updates nothing on the SCCM server. Can someone help me please?

So similar to what I talked about in this answer the main problem here is that Microsoft uses a special method to serialize their XML. The deserialization still works with using the default classes but to serialize again there is no documentation as to how to (I'm pretty sure it is possible but I am not knowledgeable enough to do it)
Instead of documentation they provide wrapper classes for this which are shipped with the SCCM Console (Located in the bin directory of the Installation folder of the Console).
In this case this would be Microsoft.ConfigurationManagement.ApplicationManagement.dll. Unlike in powershell where the dependencies in the same path seem to be loaded as well you seem also to have to reference at least Microsoft.ConfigurationManagement.ApplicationManagement.TaskSequenceInstaller.dll as well.
There are also further dlls with names like Microsoft.ConfigurationManagement.ApplicationManagement.MsiInstaller.dll present however at least in my tests the two above were the only ones needed, but if you notice the deserialization failing with "InvalidPropertyException" errors you might need the dll matching your specific application type.
With those two dlls referenced you can write something like this (note I deserialized using the dll as well because why not if it is already loaded and it creates a nice application object to directly modify the properties. This is however technically not necessary. You could deserialize like in your example and only use the serialization part.
ManagementObject obj = new ManagementObject(#"\\<siteserver>\root\SMS\site_<sitecode>:SMS_Application.CI_ID=<id>");
Microsoft.ConfigurationManagement.ApplicationManagement.Application app = Microsoft.ConfigurationManagement.ApplicationManagement.Serialization.SccmSerializer.DeserializeFromString(obj["SDMPackageXML"].ToString(), true);
app.AutoInstall = true;
obj["SDMPackageXML"] = Microsoft.ConfigurationManagement.ApplicationManagement.Serialization.SccmSerializer.SerializeToString(app, true);
obj.Put();
Now one thing to keep in mind is that is can be a little tricky referencing the applications by their CI_ID because if you update the application the id for the currently valid version of the app changes (the old id still can be used to reference the older revision). So if you change the application gotten using the ID and then change it back with the same ID it will look like only the first change worked. I don't know if this is problematic for you (If you just get all IDs then change every application only once it should not matter) but if it does you can search for the application using their name plus isLatest = 'true' in the WQL query to always get the current one.

C# code completion with NRefactory 5

I just found out about NRefactory 5 and I would guess, that it is the most suitable solution for my current problem. At the moment I'm developing a little C# scripting application for which I would like to provide code completion. Until recently I've done this using the "Roslyn" project from Microsoft. But as the latest update of this project requires .Net Framework 4.5 I can't use this any more as I would like the app to run under Win XP as well. So I have to switch to another technology here.
My problem is not the compilation stuff. This can be done, with some more effort, by .Net CodeDomProvider as well. The problem ist the code completion stuff. As far as I know, NRefactory 5 provides everything that is required to provide code completion (parser, type system etc.) but I just can't figure out how to use it. I took a look at SharpDevelop source code but they don't use NRefactory 5 for code completion there, they only use it as decompiler. As I couldn't find an example on how to use it for code completion in the net as well I thought that I might find some help here.
The situation is as follows. I have one single file containing the script code. Actually it is not even a file but a string which I get from the editor control (by the way: I'm using AvalonEdit for this. Great editor!) and some assemblies that needs to get referenced. So, no solution files, no project files etc. just one string of source code and the assemblies.
I've taken a look at the Demo that comes with NRefactory 5 and the article on code project and got up with something like this:
var unresolvedTypeSystem = syntaxTree.ToTypeSystem();
IProjectContent pc = new CSharpProjectContent();
// Add parsed files to the type system
pc = pc.AddOrUpdateFiles(unresolvedTypeSystem);
// Add referenced assemblies:
pc = pc.AddAssemblyReferences(new CecilLoader().LoadAssemblyFile(
System.Reflection.Assembly.GetAssembly(typeof(Object)).Location));
My problem is that I have no clue on how to go on. I'm not even sure if it is the right approach to accomplish my goal. How to use the CSharpCompletionEngine? What else is required? etc. You see there are many things that are very unclear at the moment and I hope you can bring some light into this.
Thank you all very much in advance!

I've just compiled and example project that does C# code completion with AvalonEdit and NRefactory.
It can be found on Github here.

Take a look at method ICSharpCode.NRefactory.CSharp.CodeCompletion.CreateEngine. You need to create an instance of CSharpCompletionEngine and pass in the correct document and the resolvers. I managed to get it working for CTRL+Space compltition scenario. However I am having troubles with references to types that are in other namespaces. It looks like CSharpTypeResolveContext does not take into account the using namespace statements - If I resolve the references with CSharpAstResolver, they are resolved OK, but I am unable to correctly use this resolver in code completition scenario...
UPDATE #1:
I've just managed to get the working by obtaining resolver from unresolved fail.
Here is the snippet:
var mb = new DefaultCompletionContextProvider(doc, unresolvedFile);
var resolver3 = unresolvedFile.GetResolver(cmp, loc); // get the resolver from unresolvedFile
var engine = new CSharpCompletionEngine(doc, mb, new CodeCompletionBugTests.TestFactory(resolver3), pctx, resolver3.CurrentTypeResolveContext );
Update #2:
Here is the complete method. It references classes from unit test projects, sou you would need to reference/copy them into your project:
public static IEnumerable<ICompletionData> DoCodeComplete(string editorText, int offset) // not the best way to put in the whole string every time
{
var doc = new ReadOnlyDocument(editorText);
var location = doc.GetLocation(offset);
string parsedText = editorText; // TODO: Why there are different values in test cases?
var syntaxTree = new CSharpParser().Parse(parsedText, "program.cs");
syntaxTree.Freeze();
var unresolvedFile = syntaxTree.ToTypeSystem();
var mb = new DefaultCompletionContextProvider(doc, unresolvedFile);
IProjectContent pctx = new CSharpProjectContent();
var refs = new List<IUnresolvedAssembly> { mscorlib.Value, systemCore.Value, systemAssembly.Value};
pctx = pctx.AddAssemblyReferences(refs);
pctx = pctx.AddOrUpdateFiles(unresolvedFile);
var cmp = pctx.CreateCompilation();
var resolver3 = unresolvedFile.GetResolver(cmp, location);
var engine = new CSharpCompletionEngine(doc, mb, new CodeCompletionBugTests.TestFactory(resolver3), pctx, resolver3.CurrentTypeResolveContext );
engine.EolMarker = Environment.NewLine;
engine.FormattingPolicy = FormattingOptionsFactory.CreateMono();
var data = engine.GetCompletionData(offset, controlSpace: false);
return data;
}
}
Hope it helps,
Matra

NRefactory 5 is being used in SharpDevelop 5. The source code for SharpDevelop 5 is currently available in the newNR branch on github. I would take a look at the CSharpCompletionBinding class which has code to display a completion list window using information from NRefactory's CSharpCompletionEngine.

NUnit is not failing test with dynamic keyword of .Net 4.0

I am using NUnit with Visual Studio Express Edition 2010 for C#, Now, normally test works fine. But whenever I try to use Massive.cs, which is open source api to access database. Test fails from that file only. Now, if I run the application, api is working fine. I have created a different library file to access data base.
I seriously don't understand the error. It is just giving error that object reference is not set to an object. But if I run the code, it works fine. I am using dynamic keyword as shown in link of api above. Does that making problem with NUnit ?
Is there any other way to test in this type of Scenarios?
Here are the further details of the code,
Test class is like this
dynamic item = new Item();
item.Insert(new { Name = "Maggi", Description = "Its 2 Min Nuddles", IsDelete = false });
var items = item.All();
Assert.AreEqual("Maggi", items.FirstOrDefault().Name);
Now, I have put test here. Which gives error like shown in image,
Now if I run code in console application, then code is working fine, code snippet is given below
dynamic item = new Item();
item.Insert(new { Name = "Maggi", Description = "Its 2 Min Nuddles", IsDelete = false });
var result = item.All();
foreach (var i in result)
{
Console.WriteLine(i.Name + i.Description);
}
Console.Read();
Here, code is working and same thing is not working with NUnit Test. Please have a look and help me out. Please let me know if any further information is needed from my side.

Most probable explanation is that you haven't set up your connection string in the test project.
If you are using NUnit, just put it in app.config of your test project.

Solved... There is a issue with NUnit Testing. It was not taking config file pefectly. So, I made two changes. Changes I have done in Project setting.
First change is to change Application Base to bin\debug just give application base as this and then config file to .config to .exe.config and things are up and running. :)

Rhino Mock vs debug mode?

my problem is following:
I have ms unit test which uses stubbed http context for mvc routing tests. But one part of code (which uses rhino mock) is problematic:
var httpContextMock = MockRepository.GenerateStub<HttpContextBase>();
httpContextMock.Stub(c => c.Request.AppRelativeCurrentExecutionFilePath)
.Return(url);
In debug mode, second line throws an exception:
Why such an error occurs ? While tests are fired without debugger, everything works fine.
Regards

This is really weird. What's strange to me is that your code works in non-debug mode. The Request property is not stubbed, so you can't really know what it would return. You may try the following:
var httpContextMock = MockRepository.GenerateStub<HttpContextBase>();
var httpRequestMock = MockRepository.GenerateStub<HttpContextBase>();
httpContextMock.Stub(c => c.Request).Return(httpRequestMock);
httpRequestMock.Stub(c => c.AppRelativeCurrentExecutionFilePath).Return(url);

I was having this issue with mine as well, and fixed it by deleting the .suo file for the solution.
I seem to also get different exceptions when toggling the Break when Common Language Runtime Exception is thrown setting, which is stored in the suo file (Debug Menu -> Exceptions)

The problem is your stub method. By using only .Return() it will give this value back only once. If you don't care about how many times the stub should return the value you should use .Return().Repeat.Any().

How to the see output from unit-tests in the Test-Result window in VS2010?

I'm new to unit testing and I want to see output from my tests.
Let's assume I'm testing for the existance of certain objects:
List<MyObject> actual = target.GetMyObjects();
Assert.IsTrue(actual.Count > 0, String.Format("{0} objectes fetched", actual.Count));
In the 'Test Result' window in VS2010 I want to see the result of "String.Format("{0} objectes fetched", actual.Count)".
Is that possible?

Found it:
I added the column Output(StdOut) to the Test Result window.
I changed the end of my test method to this:
bool success = actual.Count > 0;
Assert.IsTrue(success, "No models in the database");
if (success)
{
Console.Write(String.Format("{0} models fetched", actual.Count));
}

Yes this is possible. If the test fails whatever message that you put in the second parameter might be useful.In your case if the count value is important for you to debug the error go ahead with it.
Even if the failing or succeeding the test is automated later when debugging this information might be helpful. http://www.creatingsoftware.net/2010/03/best-practices-for-assert-statements-in.html

Alternatively you could use
Debug.Print("whatever");
And then when you run your test, you get a hyperlink "Output" in the success/fail window which will show all of your debug messages.
Obviously you need to add
Using System.Diagnostics;
Dom

No, you don't want to see the output.
Each unit test must either succeed or fail. This enables the test runner to aggregate the test results into a single Fail/Pass test result. If human inspection is required, the point of unit testing is lost - it must be automated.
