I need to extract the list of dependencies out of a compiled dll. The dll is written in either c# or vb.net, and this process should be done recursively, i.e. a dependency might have a dependency of its own and so on..
Telerik's "JustDecompile" works perfectly, but I want to write code that does that, so I can have a tree of dependencies at my disposal.
Any ideas?
My version of code (shows all dependencies of dependent assemblies):
public IEnumerable<Assembly> GetAssemblyDependencies(Assembly assembly)
{
HashSet<string> hash = new HashSet<string>();
Func<AssemblyName, Assembly> loader = (name) =>
{
try
{
return Assembly.Load(name.FullName);
}
catch
{
return null;
}
};
List<Assembly> queue = new List<Assembly>() { assembly };
List<Assembly> newQueue = new List<Assembly>();
while (queue.Count != 0)
{
foreach (var asm in queue.SelectMany(e => from x in e.GetReferencedAssemblies()
let loadedAssembly = loader(x)
where loadedAssembly != null
select loadedAssembly))
{
string fullName = asm.FullName;
if (!hash.Contains(fullName))
{
// new assembly
hash.Add(fullName);
yield return asm;
newQueue.Add(asm);
}
}
var temp = queue;
queue = newQueue;
newQueue = temp;
newQueue.Clear();
}
}
Usage:
foreach (var assembly in from e in
GetAssemblyDependencies(this.GetType().Assembly)
orderby e.FullName
select e)
{
Console.WriteLine(assembly.FullName);
}
Result (for my test console):

You don't need anything special, you can use the built-in System.Reflection classes:
public static void DisplayReferences() {
Assembly assembly = Assembly.Load( ... );
HashSet<String> seen = new HashSet<String>();
DisplayReferences( 0, seen, assembly.GetName() );
}
private static void DisplayReferences(Int32 indent, HashSet<String> seen, AssemblyName name) {
Assembly assembly = Assembly.Load( name )
foreach(AssemblyName childName in assembly.GetReferencedAssemblies() ) {
if( !seen.Contains( childName.FullName ) ) {
seen.Add( childName.FullName );
Console.WriteLine( "{0}{1}", "".PadLeft( indent ), childName.FullName );
DisplayReferences( indent + 1, childName );
}
}
}

We recently migrated one project from Azure Cloud Services (classic) to Service Fabric. It is a ASP.NET WebAPI. Since then we are getting a lot of SocketException in the Deserialize method . The code looks like:
using (var decompressionStream = new GZipStream(Request.Body, CompressionMode.Decompress))
{
using (var sr = new StreamReader(decompressionStream))
{
// https://www.newtonsoft.com/json/help/html/Performance.htm
using (var jsonReader = new JsonTextReader(sr))
{
model= Serializer.Deserialize<Model>(jsonReader);
}
}
}
The exception is:
Message:
An established connection was aborted by the software in your host machine
Sometime we get:
The read operation failed, see inner exception. One or more errors occurred. An existing connection was forcibly closed by the remote host An existing connection was forcibly closed by the remote host.

Earlier the code in Classic Service used to be like this and used to work fine:
Model model;
try
{
using (var sr = await OpenDecompressedBodyAsync(request.Content))
{
using (var jsonReader = new JsonTextReader(sr))
{
model = Serializer.Deserialize<Model>(jsonReader);
}
}
}
private async Task<StreamReader> OpenDecompressedBodyAsync(HttpContent requestContent)
{
var body = await requestContent.ReadAsStreamAsync();
var gzip = new GZipStream(body, CompressionMode.Decompress);
var sr = new StreamReader(gzip);
return sr;
}
We have tried a lot of things, however, the exception still exists. Also, it is not too common. Happens once in a while. The data volume is very high and each Request.Body can have upto 2-3MB of data. Can someone help why we are getting SocketException?
Try to disable firewall/antivirus, and test.
If it works. it means you need to allow specific port or create a new rule for this.
I recently added Storage queue to my existing application. It has nothing new comparing to other queue triggers I have already been running. Except the volume of messages it may get. We tested many times in Dev and it was working fine. We then deployed it to Prod with better resources, tried running and It was working as expected.
Then later an hour or so, we got system wide error,
Expression of type 'Microsoft.ApplicationInsights.TelemetryClient' cannot be used for constructor parameter of type 'Microsoft.ApplicationInsights.TelemetryClient' (Parameter 'arguments[0]')
All of our other HTTP / Queue trigger had same error. Here is call stack,

The Queue Trigger, which caused this problem, is a Twilio utility which updates calls as per requirements and can be triggered heavily. Like few tens per second.
So my question is what happened suddenly that it was generating this error for all azure functions? Was it a system crash? Was it the volume of requests it is getting? Do our resources fall short? Or our TelemetryClient has too many request in few seconds? Anything which can throw some light on this issue would be really helpful.
We have an application built in .NET with SQL Server as database where we are doing INSERT operations using EF(Entity Framework) and GET Operations using ADO.NET.
We are facing an issue recently in app where sometimes we are unable to do INSERT operation with exception of Timeout. We are able to fetch the data from application but unable to insert any data.
To resolve this we need to restart the SQL Server instance every time. But after one or two days again same situation arises where we are unable to do INSERT operations
NOTE : In ConnectionString we have kept Connection TimeOut value= 180.

So we have our Twilio callbacks setup to validate incoming requests, via the TwilioRequestValidator documented here.
However, something we're seeing, is that the production server will run for weeks with no problems, and then suddenly start failing with a CryptographicException. This causes all incoming Twilio requests to fail.
We have a call-stack (thanks to Azure Application Insights):

And we have some application code, here:
[AttributeUsage(AttributeTargets.Method)]
public class ValidateTwilioRequestAttribute : ActionFilterAttribute
{
private readonly RequestValidator _requestValidator;
public ValidateTwilioRequestAttribute()
{
var authToken = ConfigurationManager.AppSettings["TwilioAuthToken"];
_requestValidator = new RequestValidator(authToken);
}
public override void OnActionExecuting(ActionExecutingContext actionContext)
{
var context = actionContext.HttpContext;
if (!IsValidRequest(context.Request))
{
actionContext.Result = new HttpStatusCodeResult(HttpStatusCode.Forbidden);
}
base.OnActionExecuting(actionContext);
}
private bool IsValidRequest(HttpRequestBase request)
{
var signature = request.Headers["X-Twilio-Signature"];
Debug.WriteLine(request.Headers["X-Twilio-Signature"]);
//var requestUrl = request.RawUrl;
var requestUrl = rewriteUri(request.Url.AbsoluteUri);
Debug.WriteLine("URI is: " + rewriteUri(request.Url.AbsoluteUri));
return _requestValidator.Validate(requestUrl, request.Form, signature);
}
private string rewriteUri(string absoluteUri)
{
//check to make sure we're not replacing 'https' with 'httpss'
if (!absoluteUri.Contains("https"))
{
return Regex.Replace(absoluteUri, #"http", "https");
}
return absoluteUri;
}
}
Any ideas on what could be causing this? Ideally, I'd like to handle this exception state, but I'm not sure how to handle the exception without knowing what the cause is.
EDIT: I'm getting this error message when I drill into the exception in application insights:
"Hash not valid for use in specified state."
EDIT #2: A quick search on that error messages digs up this interesting discussion on the thread safety of the Cryptography object.
Looks like this is a bug in the Twilio-csharp library. I believe they're using their Sha1 member in a non-thread safe manner.
I've hacked up a solution to re-init the class in the event of a CryptographicException. Since a server restart is fixing the issue, I think a force re-init of the class is called for.
try
{
return _requestValidator.Validate(requestUrl, request.Form, signature);
}
catch (CryptographicException e)
{
//if the request fails, re-init the class and try again
var authToken = ConfigurationManager.AppSettings["TwilioAuthToken"];
_requestValidator = new RequestValidator(authToken);
return IsValidRequest(request);
}
EDIT: Worth noting that this fix is causing knock-on issues related to the non-thread safe manner in which the library is used.
i have been trying to figure this out with my co-workers for a while now.
i use Ngen to Make Native images and boost my Applications performance on the clients.
lets assume the Exe Filename is Example.exe
what i try to do in the app is that i do ngen install example.exe,and the ngen will install native images for the assebmlies
however here is the problem :
if i try an Elevated CMD and run C:\Windows\Microsoft.NET\Framework64\v4.0.30319\ngen Display example.exe
the example.exe file name and the version of the native image is displayed,however,using the following code which does the same thing in the windows forms c#,it does not display the filename and version of the example.exe file,and displays the dependencies instead,such as Telerik and so on.
so my question is why does the CMD return the correct result while the process returns the dependencies instead of the filename and version itself?
here is some of my code:
public static bool Run()
{
var f = new Loading();
bool state = false;
var b = new BackgroundWorker();
string runtimeStr = RuntimeEnvironment.GetRuntimeDirectory();
string ngenStr = Path.Combine(runtimeStr, "ngen");
Process process = new Process
{
StartInfo =
{
FileName = ngenStr,
WindowStyle = ProcessWindowStyle.Hidden,
UseShellExecute = false,
RedirectStandardOutput = true,
RedirectStandardError = true,
CreateNoWindow = false
}
};
if (Environment.OSVersion.Version.Major >= 6)
{
process.StartInfo.Verb = "runas";
}
process.StartInfo.Arguments = "display " + Application.ProductName;
process.Start();
// process.WaitForExit();
string stdoutx = process.StandardOutput.ReadToEnd();
process.WaitForExit();
}
however the stdoutx string does not contain the example.exe filename or version
EDIT : examples of what should be and what is :
this is what the cmd returns which is the correct result :
Example, Version=1.0.0.19, Culture=neutral, PublicKeyToken=null <debug>
this is what is :

Yes, you are not doing this correctly. The syntax of the command you are using is:
ngen.exe display [assemblyName | assemblyPath]
Note the difference between assemblyName and assemblyPath. When you ran it from cmd.exe you typed "example". And thus specified the (partial) assembly name. In your code, you used "example.exe". And the Environment.CurrentDirectory is set correctly by accident, a common accident. So Ngen.exe can find the file and it gets chatty. Listing not just the assembly name but also the native images for all of its dependencies. Like Klik.Windows.Forms.EntryLib etcetera.
Not the only problem, note that you specified the partial assembly name. You want to make sure that the specific version of your assembly was ngen-ed. Make the code look like this instead:
process.StartInfo.Arguments = "display \"" +
System.Reflection.Assembly.GetEntryAssembly().FullName + "\"";
And test it with Project > Properties > Debug tab > untick the "Enable the Visual Studio hosting process" checkbox.
Secondary things to fret about are the bitness of the native images (x86 vs x64) and getting your app elevated so you can install the native images, something you normally only have a shot at when your app is installed.
