I have developed a COM+ Component in C# be inheriting ServicedComponent.
Here is how it looks like:
[Transaction(TransactionOption.Required)]
[ClassInterface(ClassInterfaceType.AutoDual)]
[EventTrackingEnabledAttribute(true)]
[JustInTimeActivation]
[ObjectPooling(Enabled = true, MinPoolSize = 10, MaxPoolSize = 30, CreationTimeout = 15000)]
[Synchronization]
class MyComponent: System.EnterpriseServices.ServicedComponent
{
[AutoComplete(true)]
public string getHello()
{//2nd breakpoint
ContextUtil.SetComplete();
return "HelloWorld";
}
}
I have another test project from which I call this component.
class Program
{
static void Main(string[] args)
{
MyComponent myComp = new MyComponent();
myComp.getHello();//1st Breakpoint
}
}
I am not able to reach 2nd Breakpoint. This was working before I switched to VS 2012. Strange thing is after switching to 2012 its no longer working in VS 2010 too.
I've already tried,
Attach to process
Unchecked "Enable Just My Code" in debug settings
Can someone please give direction from here?
UPDATE 1
From the links given by Mike, I tried symchk for my DLL in the same folder where DLL and PDB files were there. It fails with error saying PDB mismatched or not found. I don't know how to resolve this error.
You may be missing the .pdb file in your project.

I am trying out Unity for my Game Design course, but I can't seem to get the code to work. I suspect it is because Visual Studio (which I write my code on) is not connecting to Unity properly, and here's why I think this:
For one thing, whenever I try to put the code on an object, it prints out this error:
Can't add script behaviour CallbackExecutor. The script needs to derive from MonoBehaviour!
This is despite the fact that nowhere is the code called CallbackExecutor, and the script apparently does derive from MonoBehaviour.
Second, when I load up the code onto Visual Studio, I get this error message:
C:\Users\cemya\Documents\D&D Roguelight Project\Assembly-CSharp.csproj : error : The project file could not be loaded. Could not find file 'C:\Users\cemya\Documents\D&D Roguelight Project\Assembly-CSharp.csproj'. C:\Users\cemya\Documents\D&D Roguelight Project\Assembly-CSharp.csproj
The problem is I don't know why it's not connecting. There's no option to import the package (which implies it's already imported), and I do have a package for Unity.
I'm using Visual Studios 2017 (specifically, I'm using the 2d setup most of the time), Unity version 2018.2.4f1, and the package is called Visual Studio 2017 Tools for Unity [Experimental], which is what was automatically downloaded when I began to set up coding for Unity. Since I got this version automatically, I believe that this should be a common problem, but I can't seem to find real answers on it (I even asked on the Unity forms themselves!)
I can show you the code if you think that would help.
UPDATE: I have just updated Unity to 2018.2.5f1 and tested it with the code that has actual code. All that happened is that the name for the error message is different:
Can't add script behaviour TMP_CoroutineTween. The script needs to derive from MonoBehaviour!
Also, here is the code for the one I'm testing, if it helps:
public class RollScript : MonoBehaviour
{
Random rand = new Random();
int r = 20;
int m = 5;
// Use this for initialization
void Start ()
{
int rolling = DieRoll(r, m);
print(rolling);
}
// Update is called once per frame
void Update ()
{
}
int DieRoll (int roll, int mod)
{
int get = rand.next(1, roll);
int result = get + mod;
return result;
}
}
UPDATE 2: I have checked with visual studio, and the error message there isn't there anymore, so that's an improvement.
UPDATE 3: I have created a new project and I have not run into issues there. I guess the problem was the code's connection to older editions.
This Can't add script behaviour TMP_CoroutineTween. The script needs to derive from MonoBehaviour! error has been mentioned in a few places on the internet, but with no satisfactory answers. This seems to be the only StackOverflow question about it.
I suspect it happens when there are un-fixed compile-time errors while you're adding a script to a GameObject. I had this problem just now, and after I fixed the errors, I was able to add the script. However, I tried to confirm this by adding a syntax error and then adding a script, but I still didn't get the Can't add script behavior error. So that's odd, but if you're encountering that error, I suggest fixing any compile-time errors and see if that works. (Whether it works or not, please reply to this question with the result.)
I recently inherited a set of code that includes a .mdproj file. After a bit of googling, I was able to determine this is a Mono Development project. What I wasn't able to resolve was if this is meant to be opened in Visual Studio or not. All of the other projects in the solution are C# projects. So:
Is it possible to open a Mono Development project in VS2010?
If not, can I convert it to a C# project?
Should I use VS2010, or should I use MonoDevelop?
Any insight into this would be much appreciated. I am not familiar with MonoDevelop.
Edit: Turns out that Xamarin Studio cannot open the file either..back to googling.
Update:
Opening the file in a text editor reveals the following:
"General"
{
"SccProjectName" = "\"$/BNT_AVM/CAT/SRC/Enhancement/CATApp/CATAnalysisProject\", BYRCAAAA"
"SccLocalPath" = "."
"SccAuxPath" = ""
"SccProvider" = "MSSCCI:Microsoft Visual SourceSafe"
"ProjectIdGuid" = "{F7615CCA-82F9-41F8-BB04-367601CCBE8A}"
"ShowAllFiles" = "T"
}
"Configurations"
{
"Debug|Win32"
{
}
"Release|Win32"
{
}
}
"Folders"
{
}
"Files"
{
"Model1.mdx"
{
"ProjRelPath" = "T"
}
}
"ProjStartupServices"
{
}
"Globals"
{
}
Does anyone recognize the format?
Since you have pasted its content, then it is clear that this .mdproj file is a model project for Rational XDE. It has nothing to do with MonoDevelop, though it uses .mdproj as file extension.
And the reference of Model1.mdx is a UML model.
Check the reference links and you will see where .mdproj and .mdx are mentioned.
However, IBM no longer develops Rational XDE. So you will have to migrate such projects according to IBM's recommendations,

I'm trying to allow a user to enter data into a textbox that will be added to the web.config file. I've added the relevent lines to the web.config file but when I make this class all goes wrong.
I keep getting the are you missing a using directive or assembly refenrence error whenever I try to run my app. I have looked at the other times this question has been asked and can't seem to figure out where I'm going wrong.

Any help is appreciated
You probably don't have the System.Configuration dll added to the project references. It is not there by default, and you have to add it manually.
Right-click on the References and search for System.Configuration in the .net assemblies.
Check to see if it is in your references...
Right-click and select Add Reference...
Find System.Configuration in the list of .Net Assemblies, select it, and click Ok...
The assembly should now appear in your references...
.Net framework of the referencing dll should be same as the .Net framework version of the Project in which dll is referred
If you've tried the above solutions and haven't found the answer, make sure that the .NET versions of all projects are the same.
I ran into this problem when importing a .NET version 4.6.1 into a .NET version 4.6.2 project. Without any warnings from Visual Basic!
More Info: The type or namespace name could not be found
Your using statements appear to be correct.
Are you, perhaps, missing the assembly reference to System.configuration.dll?
Right click the "References" folder in your project and click on "Add Reference..."
This problem would be caused by your application missing a reference to an external dll that you are trying to use code from. Usually Visual Studio should give you an idea about which objects that it doesn't know what to do with so that should be a step in the right direction.
You need to look in the solution explorer and right click on project references and then go to add -> and look up the one you need. It's most likely the System.Configuration assembly as most people have pointed out here while should be under the Framework option in the references window. That should resolve your issue.
I have observed a quote ' in your 1st line and also at the end of your last line.
'using System.Collections.Generic;
Is this present in your original code or some formatting mistake?
I had the same problem earlier today. I could not figure out why the class file I was trying to reference was not being seen by the compiler. I had recently changed the namespace of the class file in question to a different but already existing namespace. (I also had using references to the class's new and previous namespaces where I was trying to instantiate it)
Where the compiler was telling me I was missing a reference when trying to instantiate the class, I right clicked and hit "generate class stub". Once Visual Studio generated a class stub for me, I coped and pasted the code from the old class file into this stub, saved the stub and when I tried to compile again it worked! No issues.
Might be a solution specific to my build, but its worth a try.
In some cases, when necessary using has been obviously added and studio can't see this namespace, studio restart can save the day.
I was getting warnings about different versions in .NET framework; I ignored them.
The project compiles fine making the change in the solution's properties.
I'm using Visual Studio Code and could not use instructions from above so I found another way to fix the problem with referencing to namespace from another file.
All what need to be done is to add include to your .csproj file e.g:
<ItemGroup>
<Compile Include="filename.cs" />
</ItemGroup>
Then you can use namespaces from filename.cs
The following technique worked for me:
1) Right click on the project Solution -> Click on Clean solution
2) Right click on the project Solution -> Click on Rebuild solution
I created a new VSIX extension project in Visual Studio 2012, and wrote a MEF classifier (as a test) that should simply highlight all text in a .mylang file. Here are the relevant parts of my .NET 4.5 code:
internal static class MyLangLanguage
{
public const string ContentType = "mylang";
public const string FileExtension = ".mylang";
[Export(typeof(ClassificationTypeDefinition))]
[Name(ContentType)]
[BaseDefinition("code")]
internal static ContentTypeDefinition MyLangSyntaxContentTypeDefinition = null;
[Export]
[FileExtension(FileExtension)]
[ContentType(ContentType)]
internal static FileExtensionToContentTypeDefinition MyLangSyntaxFileExtensionDefinition = null;
}
[Export(typeof(IClassifierProvider))]
[ContentType(MyLangLanguage.ContentType)]
[Name("MyLangSyntaxProvider")]
internal sealed class MyLangSyntaxProvider : IClassifierProvider
{
[Import]
internal IClassificationTypeRegistryService ClassificationRegistry = null;
public IClassifier GetClassifier(ITextBuffer buffer)
{
return buffer.Properties.GetOrCreateSingletonProperty(() => new MyLangSyntax(ClassificationRegistry, buffer));
}
}
internal sealed class MyLangSyntax : IClassifier { }
Here is the full code.
These are the relevant parts from my source.extension.vsixmanifest file. Based on suggestions and similar files I found across the web, I added the dependency on MPF and the two assets.
<?xml version="1.0" encoding="utf-8"?>
<PackageManifest Version="2.0.0" xmlns="http://schemas.microsoft.com/developer/vsx-schema/2011" xmlns:d="http://schemas.microsoft.com/developer/vsx-schema-design/2011">

</Assets>
</PackageManifest>
I also tried a version 1.0 manifest:

When I run it, it starts an experimental instance of Visual Studio 2012, and the Extensions and Updates window shows that my extension is active. However, it does not do anything when I load or create a .mylang file. Any exceptions I throw (as a test) from my extension are never thrown. Breakpoints are never hit, and get an exclamation mark with the following warning:
The breakpoint will not currently be hit. No symbols have been loaded for this document.
It feels as if my extension is never really loaded at all. My problem is similar to this problem and this problem, but I'm using Visual Studio 2012 which uses a new VSIX manifest format.
What I know:
I can find my DLL and VSIX file in the %localappdata%\Microsoft\VisualStudio\11.0Exp\Extensions\MyLang\VSIXProject1\1.0 folder, so I know they are copied.
Their timestamp corresponds to when I last built the project, so I know they are up-to-date.
Project Properties > Debug > Start external program: is already automatically set to C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\IDE\devenv.exe, and the Command line arguments were automatically set to /rootsuffix Exp.
The Visual Studio log (created with the /log option) has two entries related to my extension: Successfully loaded extension... and Extension is enabled....
My DLL does not appear on the Modules tab (list of all loaded DLLs) of the debugging Visual Studio, while some (not all) other extensions do appear.
It doesn't get loaded in Visual Studio 2012 or 2010 both on my laptop and my desktop PC.
What I've tried:
Set <IncludeAssemblyInVSIXContainer> to true in the .csproj file, per this suggestion, but it did not make any difference.
I can't add the line <MefComponent>|%CurrentProject%|</MefComponent> to the source.extension.vsixmanifest file as it uses a different format (2.0) than VSIX projects for previous versions of Visual Studio (1.0).
This suggestion (setting IncludeAssemblyInVSIXContainer and friends in my .csproj to true) but it does not make a difference. And my breakpoints are still showing the warning and not being hit.
Reset the VS Experimental instance using the Reset the Visual Studio 2012 Experimental Instance shortcut in the Start Menu, as per this suggestion. It didn't make a difference.
How can I at the very least be sure my VSIX MEF extension is loaded and works? And if possible, how can I make by breakpoint work and debug it?
Edit: The problem is you've improperly exported your ContentTypeDefinition as a ClassificationTypeDefinition. You should use the following instead:
[Export] // <-- don't specify the type here
[Name(ContentType)]
[BaseDefinition("code")]
internal static ContentTypeDefinition MyLangSyntaxContentTypeDefinition = null;
Here's my two guesses right now:
Try removing the following line from your vsixmanifest. I assume you do not have a class in your project that extends Package, in which case Visual Studio might be refusing to load your package due to the following Asset line (your extension does not actually provide this asset).
<Asset Type="Microsoft.VisualStudio.VsPackage" d:Source="Project" d:ProjectName="%CurrentProject%" Path="|%CurrentProject%;PkgdefProjectOutputGroup|" />
If that fails, try replacing your current source.extension.vsixmanifest with one written to the old schema (version 1.0). I know this form still works in Visual Studio 2012 because all ~20 extensions I work on (with >10 public releases) use the old schema.
280Z28 solved the problem! For completeness, this is the full tried and tested code that will create a super simple VSIX Visual Studio MEF extension that colors all text in a .mylang file blue (or whatever the current keyword color is).
How to create a simple coloring MEF VSIX extension
Make sure you have the Visual Studio SDK installed. (VS2010 SP1 SDK, VS2012 SDK)
Create a new VSIX Project(From the template under Installed → Templates → Visual C# → Extensibility.)
Enter something in the Author field of the VSIX manifest editor, then save and close it.
Add references to the following libraries,version 10.0.0.0 for VS2010, or 11.0.0.0 for VS2012:
Microsoft.VisualStudio.CoreUtility.dll
Microsoft.VisualStudio.Language.StandardClassification.dll
Microsoft.VisualStudio.Text.Data.dll
Microsoft.VisualStudio.Text.Logic.dll
Microsoft.VisualStudio.Text.UI.dll
Microsoft.VisualStudio.Text.UI.Wpf.dll
Add a reference to the following library:
System.ComponentModel.Composition.dll version 4.0.0.0
Create and add a new code file MyLang.cs, and copy-and-paste the code below in it.
Edit source.extension.vsixmanifest as XML.
For Visual Studio 2010, add the following XML just before the closing tag </Vsix>, and save:
<Content>
<MefComponent>|%CurrentProject%|</MefComponent>
</Content>
(If there is already an empty <Content/>, remove it.)
For Visual Stuio 2012, add the following XML just before the closing tag </PackageManifest>, and save:
<Assets>
<Asset Type="Microsoft.VisualStudio.MefComponent" d:Source="Project" d:ProjectName="%CurrentProject%" Path="|%CurrentProject%|" />
</Assets>
(If there is already an empty <Assets/>, remove it.)
Only for Visual Studio 2010:
Unload the VSIX project (right-click the project → Unload project).
Edit the .csproj project file (right-click the project → Edit MyProject.csproj).
Change the value at <IncludeAssemblyInVSIXContainer> to true.
Save and close the file.
Reload the VSIX project (right-click the project → Reload project).
Now build and run it. When you load a .mylang file, all text should be colored blue (or whatever the default keyword color is).

private void OnBufferChanged(object sender, TextContentChangedEventArgs e)
{
foreach (var change in e.Changes)
ClassificationChanged(this, new ClassificationChangedEventArgs(new SnapshotSpan(e.After, change.NewSpan)));
}
}
}
Set <IncludeAssemblyInVSIXContainer> to true in the .csproj file, per
this suggestion.
I had exactly the same problem and this solved it. Do a full rebuild.
So I was trying to run some simple code with Code Contracts (that I haven't used for some time)
static void Main(string[] args)
{
double res = sqrt(-5);
}
static double sqrt(int a)
{
Contract.Requires(a >= 0, "a must be >= 0!");
return Math.Sqrt(a);
}
But it doesn't seem to do anything at all when I run it. From what I recall from some months ago, it should throw up an error about a being less than 0.
I reinstalled the Academic version from the Code Contracts site just to be safe and this still doesn't seem to be working. What are the steps needed to put Code Contracts to work?
EDIT: Resharper is telling me on Contract.Requires(a >= 0); that the method is being skipped, as it is either "conditional or a partial method without implementation".
Thanks
You should check this web page: link text
You should go to the project properties, Code Contracts tab and click the Runtime checkboxes.
