I need help with this following exception. I am trying to consume a web WCF web service using basicHttpSecurity etc. I had a look at the Dev Pipe for Mono and what I am consuming is in the working section.
So the service im trying to consume is AccountService.svc. The proxy that is generated has a AccountServiceClient() object that I am using. On the line where you create the object it throws an exception and there is no way of debugging and stepping into that constructor.
The strange thing is that I can consume this service on my Windows Machine going though IIS. I can also consume with my Mac PC using the mod mono extension ect. But not on Ubuntu Linux machine. Can anyone shed some light on this? Can anyone explain why this is happening? How do I fix this?
Me creating a new instance of the client.
client = new AccountServiceClient ();
The AccountServiceClient() sniplet
public partial class AccountServiceClient : System.ServiceModel.ClientBase<EServicesAccountProxy.IAccountService>, EServicesAccountProxy.IAccountService
The exception that gets thrown.
System.Reflection.ReflectionTypeLoadException: The classes in the module cannot be loaded.

A Strange thing i have noticed also is that I get a LoaderException as well (System.TypeLoadException). I don't know if it is related because the message says that it could not load type 'Npgsql.VisualStudio.NpgsqlObjectSelector' from 'Npgsql.VisualStudio, vserion=2.0.2.1, culture-neutral, PublicKeyToken=null'. Im not even using VisualStudio, im using monodevelop and XamarinStudio on my windows machine.
She source in the exception message says if comes from "mscorelib"
Any help will be appreciated.
Turns out there was an inner load exception and I had a Npgsql.VisualStudio DLL in my bin. Once i have removed that everything worked. Reflections failed to load that DLL because of missing references.

I have been using Visual Studio Code a little bit with some experimental Unity3D projects. Now I got an insiders email about the 0.2.0 update and decided to give it a go. After the update VSCode start up nicely, butit runs into errors when trying to open a .csproj file.
This is my error log

And this is not in any way restricted to Unity projects, but happens with all projects. I tried one generated with MonoDevelop and one made with Visual Studio 2010 that I downloaded.
What could be the cause of this error? It seems, that VSCode cant find a single character from the file since it refers to
/Assembly-CSharp-vs.csproj(0,0)
I do not know what caused the error on leading the projects, but it seems to have been fixed in the new 0.3.0 release.
I'm having a problems building a PCL in Xamarin Studio on the Mac. It works fine in debug mode but fody throws an exception in Release Mode.

Fody needs the debug information (*.mdb file) associated with the outputted assembly to perform the weaving step. Release builds by default turn off the Debug Information field within Build -> Compiler in a projects settings.
Having this build option set to None disables debug symbolication and results in the mdb file getting out of sync, hence the Symbol file 'XXX/obj/Release/XXX.dll.mdb' does not match assembly XXX/obj/Release/XXX.dll exception.
Therefore you need to enable Symbols Only or Full when you build projects in release mode when Fody is integrated into the build process:
You may have already, but I'd start with this if it was me:
Right click on your solution

In the "Configuration" drop down in the top left, check that the "Debug" configuration (re: Platform | Build | Deploy) matches "Release".
I am having problems with MVC4 on Mono 3. I am using the latest version in Xamarin Studio with the latest updates but when trying a HTTP POST to the web server it is returning the following error. I am using the DLL's for MVC4 from windows as the guides suggest and the Mono version of System.Web 4.0.0.0.
Any ideas how to resolve this issue or am I just better reverting to MVC3?

Since I had the same error with MVC 3 Razor like you I solved my problem by
copying following DLL's from a MVC 3 Razor Visual Studio project to my mono project.
System.Web.Helpers.dll
System.Web.Mvc.dll
System.Web.Razor.dll
System.Web.WebPages.dll
System.Web.WebPages.Deployment.dll
System.Web.WebPages.Razor.dll
This might help as well:

Is there any way to use Excel / Office libraries in Ubuntu?
I've developed a C# program that glues together an Excel spreadsheet and some VB macros. It uses the following.
Excel and Office libraries: Microsoft.Vbe.Interop.dll
Microsoft.Office.Interop.Excel.dll and Office.dll. It works perfectly fine in Windows but I can't manage to get it running on Ubuntu using Mono 3.2.
When I try to execute it (after adding the libraries that I explicitly imported using gacutil -l XXXX.dll)
the output is the following:
[ERROR] FATAL UNHANDLED EXCEPTION: System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.DllNotFoundException: ole32.dll

Any help or direction would be highly appreciated. Thanks in advance.

The Excel / Office integration libraries require Office to already be installed to run - just copying the PIAs (e.g. Microsoft.Office.Interop.Excel.dll) is insufficient, as they are to act as the bridge to the COM layer exposed by Excel et al. Without the COM layer, there's nothign to perform the work you're asking of it.
I've recently came across the blog article Monovation: Assembly Injection into Live Processes of Miguel de Icaza.
I've tried to reproduce it with no luck. My command line was
'csharp --attach 5612'
where 5612 was the pid of a simple running mono 'Hello World' console application.
I've got an exception (see the stack trace above).
What I've tried so far:
using Mono 2.10.8 (csharp and csharp2 commands for .NET 4 and 2 )
using Mono 3.2.3 (only csharp command exists)
Q1: Missed I something?
Q2: Is it possible that this virtual machine attach facility (see Monovation: Assembly Injection into Live Processes) is available only in Linux installations? (I am using Windows 7) It sounds an easy answer, but Miguel does not mention platform restriction in his article, and the whole point of mono is the multiplatform, is not it? So I can not believe it so easy.
Q3: What about Mac? Is there any chance it will work in a Mac, or we must look elsewhere?
Thx in advance
