I am developing a WCF REST service (.net 4) that uses the GDAL libraries. It works great on my development machine but throws an exception on the server (Windows Server 2008 R2). The code fails at
OSGeo.GDAL.Gdal.AllRegister();
Here's the exception:
20130214081020 Exception Message: The type initializer for 'OSGeo.GDAL.GdalPINVOKE' threw an exception.
20130214081020 Exception Stack Trace: at OSGeo.GDAL.GdalPINVOKE.AllRegister()

20130214081020 Inner exception stack trace: at OSGeo.GDAL.GdalPINVOKE.SWIGExceptionHelper..ctor()
at OSGeo.GDAL.GdalPINVOKE..cctor()
I have copied the GDAL files to the server and have added the path to those in the PATH environment variable.
Any thoughts on what I'm missing? Thanks!
It turns out that I needed to add the *_wrap.dll files to the bin folder of my service.

I am getting the following error when trying to host my WCF service in windows on the server. I am installing it using InstallUtil.exe.
I hosted the same service on my local system. It worked perfectly fine. But not working when trying on the server.

Affected parameters are:
assemblypath = D:\wwwroot\CareScoutServices\ABC.servicehost.exe
logfile = D:\wwwroot\ABCServices\ABC.servicehost.InstallLog
logtoconsole =

The inner exception System.NullReferenceException was thrown with the following error message: Object reference not set to an instance of an object..

Can someone please help resolve this error.
This is basic but try running the InstallUtil as an administrator.
I have ran into this issue the past few weeks ago and I still can not figure out why.
I have a BizTalk orchestration that receives a BizTalk message, processes it and eventually writes it to a file. For simplicity sake, let say, our goal is to take the message (which is actually a survey) and save it to a folder as is. I have created a public receive port to catch the msg and a send port to write the result out to disk.
I have successfully deployed the project and have successfully published it to IIS. I was able to see the WCF service in IIS and have set it to use Framework 4.0. I have set up all the relevant receive and send ports and have started the application successfully from BizTalk management console. (The receive location was automatically created when I published the wcf service, the send location is a type FILE located in a folder in the computer)
From DefaultSite in IIS, I could see my WCF. However, when I tried http://localhost/TestSurvey/TestSurvey_Orchestration_1_getSurveyPort.svc,
I got the following error:
Server Error in '/TestSurvey' Application.

My question is: what is it that BizTalk was trying to login? Domain\ComputerName$ is definitely not a user. I have not tried to access any database from the orchestration. I believe my IIS was set up correctly as I have created a quick and dirty wcf service test from VS2010 and published it to my IIS, then have successfully created a simple client to consume the wcf service test. I did not encounter the same issue when I created the wcf service test directly.
Any help or hint is highly appreciated!
EDIT
I managed to fix this: it was not the web config as it was created by BizTalk. I had to create a special app pool and tied my application to using it. In the app pool I have to use the custom credential that BizTalk is using. Using the built in credentials caused the issue I experienced. My rookie error! Once BizTalk login credential was used, everything went smoothly.
The database which is throwing the SQL exception is one of the BizTalk databases, probably the management or SSO DB.
The error is almost certainly being caused by the setup of IIS, whether the app pool identity or the web site security settings.
What is hapenning is that when you call the service for the first time IIS is compiling your service, and to do this it obviously needs access to one of the BizTalk databases, but this call is not authenticated for some reason.
This could be because the app pool user must be a member of the BizTalk Isolated Host Users group (which may be called something different depending on how BizTalk was set up.
I am trying to run the Cassia library on a remote Windows Server 2008 Terminal Server. Any methods I call I get the response below.

I was getting this error as well. Turns out that if there are no sessions for the given server it throws this exception.
Try running qwinsta /server <servername> in a WCP shell. It should return "No session exists for *".
I worked around this by checking exception message for "no more data" and don't throw it if so. It's gross but it's an open source dll.
Deployed a WCF service in IIS 6.0 gave NETWORK_sERVICE user read/write privileges.

Any thoughts?
Was told that we get 'Failed to access IIS metabase' error if we install IIS after intalling .NET Framework, and remedy is to re-install ASP.NET.
To resolve this error I have followed below steps
1. Stopped IIS
2. Ran below command in command prompt to re-install aspnet.
%windir%\Microsoft.NET\Framework\v2.0.50727\aspnet_regiis.exe -i
Result:
Start installing ASP.NET (2.0.50727).
..................................................................
Finished installing ASP.NET (2.0.50727).
3. Re-started IIS and WCF service is responding without any issues.
I am building an application and I am using web services for getting data from a server. It was working fine when I was developing on my XP machine but had to switch to Windows 7. On the new machine I grabbed the latest version of the code using sourcesafe.
However, when I try to add a service reference in the solution or update an existing one I get the following error:
There was an error downloading 'http://localhost:52490/Service/CustomerService.asmx'.
The request failed with the error message:
Server Error in '/' Application.

An error occurred while receiving the HTTP response to http://localhost:52490/Service/CustomerService.asmx. This could be due to the service endpoint binding not using the HTTP protocol. This could also be due to an HTTP request context being aborted by the server (possibly due to the service shutting down). See server logs for more details.
The underlying connection was closed: An unexpected error occurred on a receive.
Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host.

If the service is defined in the current solution, try building the solution and adding the service reference again.
Does it has anything to do with the IIS or is it any configuration file I have to change in the solution?
Any help is appreciated.
How do you deploy your app to the server? Via a zip file?
Perhaps it extracts the files without the path.
