To debug Visual Studio extensions you can start an experimental instance with a certain "RootSuffix". See https://learn.microsoft.com/en-us/visualstudio/extensibility/the-experimental-instance?view=vs-2022.
Is there a way to know the provided rootsuffix in the code of your extension?
I.e. "Exp" if the instance was started with "devenv.exe /RootSuffix Exp"
The DTE object has a CommandLineArguments property which contains the information you need.
Can be retrieved with following code:
IVsAppCommandLine cmdline = (IVsAppCommandLine)GetService(typeof(SVsAppCommandLine));
cmdline.GetOption("rootSuffix", out var present, out var value)

I am typing in an example from the book, "C# 10 and .Net 6".
It is a console application with reflection.
Here is the code so far:
using System.Reflection;
Assembly? assembly = Assembly.GetEntryAssembly();
if (assembly == null) return;
// Loop through the assemlies that this app references
foreach (AssemblyName name in assembly.GetReferencedAssemblies())
{
// Load the assembly so we can read its details
Assembly a = Assembly.Load(name);
// declare a variable to count the number of methods
int methodCount = 0;
// loop through all the types in the assembly
foreach (TypeInfo t in a.DefinedTypes)
{
// add up the counts of methods
methodCount += t.GetMethods().Count();
}
//
}
I got this far and was about to type in the last part and I got the popup dialogue in the pic:
It says:
Specified argument was out of the range of valid values.
Parameter name: length
Why does this obtrusive popup keep displaying and stopping me from typing? What is it? What does it mean? Why does it not wait for you to try and build, compile or run before reporting the problem.
What is this and how do you make it go away?
I just want to add I was able to type it all in and the example runs correctly. But why does VS 2022 keep displaying this popup while I am trying to type?
This looks like a problem with Visual Studio or an extension. It's not a problem with your code.
You could try:
Restarting VS,
Restarting Windows,
Repairing/updating/reinstalling VS.
Does somebody know if/how it is possible to obtain the minor Visual Studio version that is currently running, from within a VSIX extension?
I've already found the following property, but we would like to have the more detailed version number (more parts). https://learn.microsoft.com/en-us/dotnet/api/envdte._dte.version?view=visualstudiosdk-2017
The following code shows "16.0.29306.81 D16.2" in my VS 2019:
var shell = (package as System.IServiceProvider).GetService(typeof(Microsoft.VisualStudio.Shell.Interop.SVsShell)) as Microsoft.VisualStudio.Shell.Interop.IVsShell;
object ver = null;
shell.GetProperty((int)Microsoft.VisualStudio.Shell.Interop.__VSSPROPID5.VSSPROPID_ReleaseVersion, out ver);
System.Windows.MessageBox.Show(ver.ToString());
Assuming you may want the level like X.Y.Z instead of X.0 or X.Y. (e.g: VS2017-15.9.13=>15.9=>15.0).
Sergey's great answer can help you resolve the issue if the format X.Y is enough for you. But if you want to get the full details like VS version+version number, you can consider using registry key.
For VS2015 and earlier versions you can see this vsx document and this similar issue, you can try to use RegistryKey to access the info you want from HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\DevDiv\vs\Servicing\<version>.
But since the installation experience of VS2017 has changed for the vs installer.exe. We can't access the version details about VS2017 and VS2019 under that registry key any more.
For VS2017 and VS2019, I find we can access the related info at HKEY_CURRENT_USER\Software\Microsoft\VSCommon\15.0 or 16.0\SQM\PIDs\.
If in the machine only has one edition of VS2017 and VS2019, you can use code like this to get details:
DTE dte = Package.GetGlobalService(typeof(DTE)) as DTE;
string version = dte.Version;
string editon = dte.Edition;
RegistryKey key = Registry.CurrentUser;
RegistryKey pidsKey = key.OpenSubKey("Software\\Microsoft\\VSCommon\\" + version + "\\SQM\\PIDs\\", true);
string[] instances = new string[10];
instances = pidsKey.GetSubKeyNames();
RegistryKey instanceKey = key.OpenSubKey("Software\\Microsoft\\VSCommon\\" + version + "\\SQM\\PIDs\\" + instances[0], true);
//read the details about VSManifestID
string versionInfo = instanceKey.GetValue("VSManifestID").ToString();
The versionInfo's format see here: VisualStudio/15.9.13+28307.xxx (Apart from VSManifestID, you can also use VSChanelID...)
But this won't work if you have more than one edition of same VS version in PC.(VS20xx community and enterprise in same machine). In this situation you have to add much more judgement logic with the help of dte.Version and dte.Edition.
The easiest way to find the minor part of VS is to get version information from the file "devenv.exe":
var devenvInfo = FileVersionInfo.GetVersionInfo(dte.FullName);
return new Version(devenvInfo.FileMajorPart, devenvInfo.FileMinorPart);
I am getting the following error when I try to start my Application...
[java.lang.IllegalStateException: java.lang.NullPointerException^M

xt.java:66)^M
I double checked the config file was accessible and I could read it. The code I am using looks as follows...
aC = new PDAuthorizationContext(cFile);
Is there a way to get more information on what is causing the NPE?
More information!!!
After debuging a bit, it appears the issue comes from this code (they use progaurd so it is a little hard to be 100% confident)...
Certificate[] arrayOfCertificate1 = ((KeyStore)???).getCertificateChain("DefaultID");
//Throws Null pointer (presumably because array is null)
Certificate localCertificate1 = arrayOfCertificate1[0];
EVEN MORE INFO
This appears to be some kind of dependency conflict (guess), because if I just create a sample App using PDAuthorizationContext it works fine.
Problem was related to the PD.jar version that I was using. Although I thought I was using one version I was using another. This was because on version was registered in my WebSphere library (under build path in eclipse). Once the proper library was introduced everything worked.
I'm new to ASP.NET and having a problem with a tutorial.
I've created a new MVC4 Project in VS2012 Express for Web.
And I've added a SQL Database with 1 Table "Persons" and filled it with some random testdata:
Id int (primary key, is identity=true)
name varchar(50)
birthdate date
adam 01.01.2001
berta 02.02.2002
As a Model I've used ADO.NET Entity Data Model, named it "PersonsModel.edmx"
and used the Personsdatabase for it.
To see the PersonsModel.Designer.cs file, I activated "Codegeneration Status" to "Standard". Refreshed and clicked on the PersonsModel.Designer.cs file.
But in this file I've errors... So I wanted to use something like this in my controller:
HomeController.cs:
PersonsEntities1 db = new PersonsEntities();
db.person...
but it doesn't work, and I think(?) it's because of the errors in the .Designer.cs file.
PersonsModel.Designer.cs: e.g.:
public PersonsEntities1() : base("name=PersonsEntities1", "PersonsEntities1")
{
this.ContextOptions.LazyLoadingEnabled = true;
OnContextCreated();
}
errors in the base: ... line
and in ContextOptions.
Unfortunately I've no english VS, but it says something like:
The best accordance für the overloaded System.Data.Entity.DbContext(string, System.Data.Entity.Infrastructure.DbCompiledModel)-Method has some invalid arguments
And no definition found for "ContextOptions", there is no method "ContextOptions" which accepts "MvcApplication7.Models.PersonsEntities1" as a first argument.
I'm a bit confused, because I did it like in the tutorial explained.
I think this code is in error:
base("name=PersonsEntities1", "PersonsEntities1")
There is no constructor that takes two strings. Your second argument is supposed to be of type DbCompiledModel. (See here.)
Now, I don't know why your designer would produce code that can't compile, so I'm wondering whether you have the wrong version of Entity Framework installed.
Apparently the problem was VS2012. It all works with VS2010.
I've downloaded the installer again from asp.net/mvc and added Visual Web Developer 2010 Express. After installation of VS2010 and all dependencies I tried the tutorial again and all works fine now. No wrong code in the .Designer.cs file :).
Thanks a lot Ann L. for your support. Your hint (wrong version of Entity Framework installed) prompt me to try another VS version.
In addition I've to say: I also tried VS2012 Ultimate (complete DVD version) but it didn't help.
Does omebody has ideas how to fix "Method not found: 'Void System.Web.Mvc.ViewContext..ctor(System.Web.Mvc.ControllerContext, System.Web.Mvc.IView, System.Web.Mvc.ViewDataDictionary, System.Web.Mvc.TempDataDictionary)'." exception. This solution doesn't work http://dotnetslackers.com/articles/aspnet/installing-the-spark-view-engine-into-asp-net-mvc-2-preview-2.aspx.
Thans for all.
I had to download the spark view engine source code (http://sparkviewengine.codeplex.com/Release/ProjectReleases.aspx?ReleaseId=27600). Once I did that I went through each of the projects that had a reference to the 1.0 version of System.Web.Mvc assembly and updated to reference to point to System.Web.Mvc 2.0. From there you can build the solution (in visual studio) and you will find that a whole bunch of tests start to fail. You can attempt to fix them (by adding the additional TextWriter parameter you will find is now needed). You will also see that the SparkView.cs file complains about a missing parameter. In the Render method (line 100 of the source code I downloaded) I had to update the instantiation of the wrappedViewContext to look like this (add writer to the end of the list of parameters):
public void Render(ViewContext viewContext, TextWriter writer)
{
var wrappedHttpContext = new HttpContextWrapper(viewContext.HttpContext, this);
var wrappedViewContext = new ViewContext(
new ControllerContext(wrappedHttpContext, viewContext.RouteData, viewContext.Controller),
viewContext.View,
viewContext.ViewData,
viewContext.TempData,
writer); // <-- add the writer to the end of the list of parameters
...
}
Once the code is updated you can run the build.cmd script that is in the root of the source you downloaded. The build process will create a zip file in the build/dist folder. Take those new dll's and add them to your website. Things should work once again.
At the time of this answer, MVC 2 RC2 bits are available at sparkviewengine.codeplex.com
http://sparkviewengine.codeplex.com/releases/view/41143
It was actually Erik from the post mentioned by R0MANARMY who helped get those bits out there.
Looks like you can also download compiled binaries from here. As the post says, it isn't a final (or official) release, but at least it seems like the unit tests pass.
