I have developed ASP.net application using VS-2010, C#.Net 4.0 with SharpSvn dll. When I'm working with dev server(don't have 3-Tier Architecture), it works fine. But when we are working with QA environment(have 3-Tier Architecture) it gives thread abort exception most of the time.Following shows the code and error log I have. Any help on this really appreciate.
public bool Checkout(string svnurl, string target)
{
try
{
using (_client = new SharpSvn.SvnClient())
{
_client.LoadConfiguration(Path.Combine(Path.GetTempPath(), "Svn"), true);
_client.Authentication.DefaultCredentials = new TNetworkCredential(_username, _password);
_client.Authentication.SslServerTrustHandlers += SvnSslOveride;
var targetsvn = new SvnUriTarget(svnurl);
if (_client.CheckOut(targetsvn, target))
{
Log.Info("Successfully checked out to following location : " );
Log.Info(target);
return true;
}
}
Log.Info("Unable to checkout "+ svnurl +" Svn location to target location : ");
Log.Info(target);
return false;
}
catch (Exception ee)
{
Log.Error("Error:SvnClient checkout....");
Log.Error(ee);
throw ee;
return false;
}
}
private static void SvnSslOveride(object sender, SvnSslServerTrustEventArgs e)
{
e.AcceptedFailures = e.Failures;
e.Save = true;
}

I missed <httpRuntime executionTimeout="(time in seconds)">
tag in web config and it automatically set by IIS server. The default is 110 seconds.
Note :In the .NET Framework 1.0 and 1.1, the default is 90 seconds.
After I added following line to web.config and it works fine.
<httpRuntime executionTimeout="600">
Previously it works sometimes because the time taken to SVN checkout in DEV server is less than in other environment because of the size of the repositories and network connections. Thanks all for your answers
As per my comment above, I've seen this issue. It appears to be related to plink authentication.
I resolved it by upgrading to the latest build of SharpSVN v1.7, at which point the error changed from a null-ref exception in the C++, to an SVN exception with the message "Can't create tunnel: The parameter is incorrect".
There are a few articles which explain how to resolve this, the best of which I've found here:
SVN+SSH and Sourceforge
In my case, changing the backslashes to forwardslashes in the SVN_SSH env var resolved the problem. Worth giving a shot.

I created a Windows Service starting from my .NET Core project following this
After this, I installed correctly it on my working machine and started it.
This is my service class:
using System;
using System.Diagnostics;
using System.ServiceProcess;
using System.Threading.Tasks;
namespace xxx
{
public class WindowsService
{
static void Main(string[] args)
{
System.IO.Directory.SetCurrentDirectory(System.AppDomain.CurrentDomain.BaseDirectory);
using (var service = new Service())
{
ServiceBase.Run(service);
}
}
}
internal class Service : ServiceBase
{
public Service()
{
ServiceName = "...";
}
protected override void OnStart(string[] args)
{
try
{
base.OnStart(args);
Task.Run(() => xxxx);
}
catch (Exception ex)
{
EventLog.WriteEntry("Application", ex.ToString(), EventLogEntryType.Error);
}
}
protected override void OnStop()
{
base.OnStop();
}
protected override void OnPause()
{
base.OnPause();
}
}
}
So, I copied the file and installed it also on a server. Here, when I try to start it, I get:
After this, I start a lot of googling... for example, I tried the following steps :
Go to Start > Run > and type regedit
Navigate to: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control
With the control folder selected, right click in the pane on the right and - select new DWORD Value
Name the new DWORD: ServicesPipeTimeout
Right-click ServicesPipeTimeout, and then click Modify
Click Decimal, type '180000', and then click OK
Restart the computer
The weird point here is that the voice ServicesPipeTimeout didn't exist and I created it. Comparing the server with my working machine, there are also other value not present in the server. They are:
ServicesPipeTimeout
OsBootstatPath
Here the screenshot of regedit from the server:
Are these relevant?
I also tried to reinstall the service, recompile my files... how can I fix this problem? The error appears immediatly, it doesn't wait any timeout!
I had this problem when I switched my project to another location.
When I moved the project, I had copied the files in bin/debug folder too. The issue was resolved after I cleared the debug folder and created a new build.
See if this works!
It's a bit old question but someone may find this useful.
So I had the following code in Program.cs:
builder.SetBasePath(Environment.CurrentDirectory).AddJsonFile("appsettings.json")
Changed it to:
builder.SetBasePath(Path.GetDirectoryName(Assembly.GetEntryAssembly().Location)).AddJsonFile("appsettings.json")
This seemed to fix the problem for me.
The problem with this error is that it is super generic.
Hopefully MS will give us some log in the future.
if you check the windows event viewer under applications it tells you what exactly is the exception that causes this error.
in my case the problem was i published the service in net6 and tried to run it on a pc with net7 installed. apparently it requires the exact major version that was used to publish the app.
I have a .NET application that uses a 3rd party Web Service for authentication.
My code:
var sso = new com.myclient.auth.Service();
string userID = sso.DecryptUser(encryptedUserString, decryptionKey);
This has been working for quite some time. I've since been forced to convert the application from .NET 2.0 in VS 2008 to .NET 3.5 in VS 2010 and now it no longer works. I get an error at "DecryptUser": "Received an unexpected EOF or 0 bytes from the transport stream".
I don't see any changes made to this code during the conversion. I tried the much used solution for this error of forcing SecurityProtocolType.Ssl3 -- that did not work either. If I revert back to VS 2008 and build, the page works -- no error.
Okay -- I did a full file compare for the entire project, and found this change in Properties/Settings.Designer.cs that occurred during the VS conversion:
public string MyProj_com_myclient_auth_Service {
get {
string urlSetting = System.Configuration.ConfigurationSettings.AppSettings["com.myclient.auth"];
if (urlSetting != null)
{
return urlSetting.ToString();
}
else
{
return ((string)(this["MyProj_com_myclient_auth_Service"]));
}
}
}
...was changed to:
public string MyProj_com_myclient_auth_Service {
get {
return ((string)(this["MyProj_com_myclient_auth_Service"]));
}
}
I changed it back and it is working now in the new environment.
I'm building an ASP.NET Web API endpoint that accepts 'multipart/form-data' requests. I implemented it as described in this article using .NET Framework 4.5 and Web API 2.1. A simplified version of the action method I created, looks like this:
public async Task<HttpResponseMessage> PostFile()
{
if (!Request.Content.IsMimeMultipartContent()) throw new HttpResponseException(HttpStatusCode.UnsupportedMediaType);
var rootPath = System.Configuration.ConfigurationManager.AppSettings["StorageLocation"].ToString();
var provider = new MultipartFormDataStreamProvider(rootPath);
var response = Request.CreateResponse(HttpStatusCode.OK);
try
{
await Request.Content.ReadAsMultipartAsync(provider);
// Imagine awesome logic here, unicorns and rainbows! Instead of that, we do the following:
response.Content = new StringContent("You uploaded " + provider.FileData.Count.ToString() + " files.");
}
catch (Exception e) { throw new HttpResponseException(Request.CreateErrorResponse(HttpStatusCode.InternalServerError, e)); }
return response;
}
Because the uploaded files can be very big (up to 2GiB), I want my requests to not be buffered by ASP.NET, thus avoiding high memory usage. To realize this I told Web API to stream incoming requests, instead of buffering them, as described in this article. The custom WebHostBufferPolicySelector looks something like this:
public class CustomWebHostBufferPolicySelector : WebHostBufferPolicySelector
{
public override bool UseBufferedInputStream(object hostContext)
{
System.Web.HttpContextBase contextBase = hostContext as System.Web.HttpContextBase;
if (contextBase != null && contextBase.Request.ContentType != null && contextBase.Request.ContentType.Contains("multipart")) return false;
else return base.UseBufferedInputStream(hostContext);
}
public override bool UseBufferedOutputStream(System.Net.Http.HttpResponseMessage response)
{
return base.UseBufferedOutputStream(response);
}
}
I load this guy in the Global.asax, at application start, like this:
protected void Application_Start(object sender, EventArgs e)
{
// Here, other stuff got did.
GlobalConfiguration.Configuration.Services.Replace(typeof(IHostBufferPolicySelector), new CustomWebHostBufferPolicySelector());
}
Alright, the board is set, lets get the pieces moving. If I don't use my CustomWebHostBufferPolicySelector, everything works just fine. However, when its used, I get the following exception:
Message: "An error has occurred."
ExceptionMessage: "Error reading MIME multipart body part."
ExceptionType: "System.IO.IOException"
StackTrace: " at System.Net.Http.HttpContentMultipartExtensions.<ReadAsMultipartAsync>d__0`1.MoveNext()\ \ --- End of stack trace from previous location where exception was thrown ---\ \ at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task)\ \ at System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task)\ \ at System.Runtime.CompilerServices.TaskAwaiter`1.GetResult()\ \ at ..."
With the following inner exception:
Message: "An error has occurred."
ExceptionMessage: "Unable to read the entity body in Bufferless mode. The request stream has already been buffered."
ExceptionType: "System.InvalidOperationException"
StackTrace: " at System.Web.Http.WebHost.HttpControllerHandler.<>c__DisplayClass13.<GetStreamContent>b__10()\ \ at System.Web.Http.WebHost.HttpControllerHandler.LazyStreamContent.get_StreamContent()\ \ at System.Web.Http.WebHost.HttpControllerHandler.LazyStreamContent.CreateContentReadStreamAsync()\ \ at System.Net.Http.HttpContent.ReadAsStreamAsync()\ \ at System.Net.Http.HttpContentMultipartExtensions.<ReadAsMultipartAsync>d__0`1.MoveNext()"
It looks like the request is still buffered somehow, by something else. Is there another place in the ASP.NET pipeline I should be looking? Or even IIS maybe? What are the other places in this request's lifecycle where it can be buffered, and how do I control them?
In an attempt to make the problem more clear and shareable with others, I created a simple project to try and reproduce the problem. While doing this I found the answer: disable all kinds of tracing.
In my case I had ASP.NET's own tracing functionality enabled, and also Glimpse. Both of these buffer the request before it arrives at the Web API action.
For completeness' sake, here the proper way to turn them off in your Web.Config, while testing and in production.
<configuration>
<system.web>
<trace enabled="false" />
</system.web>
<glimpse defaultRuntimePolicy="Off">
</glimpse>
</configuration>
In my case, these two were the culprits, but I can imagine there may be others, so be wary of this.
I have written the following code for login:
Session["IsLogin"] = false;
System.Configuration.Configuration config = System.Web.Configuration.WebConfigurationManager.OpenWebConfiguration("~");
if (txtPassword.Text.Trim() == string.Empty)
{
// Display Error
}
else
{
string Pwd = config.AppSettings.Settings["PWD"].Value.ToString();
FormsAuthenticationTicket formAuthTk = FormsAuthentication.Decrypt(Pwd);
string strDcryptedPwd = formAuthTk.Name.Trim().ToString();
if (txtPassword.Text.Trim() == strDcryptedPwd)
{
Session["IsLogin"] = true;
Response.Redirect("AnyPage.aspx");
}
else
{
// Error, Wrong password
}
}
Which is running fine while running through Visual studio. But when I published it it is showing the below error:
System.Web.HttpException: Unable to validate data
NOTE:
I publish the application on the
same server on which I am developing
the site.
I have tried EnableViewStateMAC =
false on page level. [Login Page]
What is the reson of this error? Why it is only appears when I have published the site?
I have changed the way to encrypt the string and the problem disapperars. I have no idea about the reason of the error, but I resolved it like this.
Hope it will help to others, who are facing the same issue.
you do not need to declare the config in the way you did, just use Configuration.AppSettings["PWD"].ToString()...

I am trying to call a service from a silverlight application, but I am getting the following error.
Uncaught Error: Unhandled Error in Silverlight Application An exception occurred during the operation, making the result invalid. Check InnerException for exception details.
This works fine locally. I don't know if it make any sense, but locally if I add the url of the webservice on a browser, I am getting the details page of the service. In the other hand, on production server, it prompts me to download it.
Does anyone know something about this?
Thanks

The fact that on the production server it "prompts you to download" would suggest that the production web server doesn't know what to do with your .svc or .asmx file. It is treating it like a normal file (.txt, .pdf etc).
Have you got all of the required items installed in production. For instance, you need the correct .NET runtime to be installed. Also, ASP.NET needs to be installed and then enabled.
To determine exactly what is happening I would recommend installing Fiddler and using it to trace what is happening when the Silverlight app calls the server. I have found this approach to be invaluable when troubleshooting Silverlight to Web Service communication problems.
