Set A Service Dependency?
Jul 16, 2009Does setting service dependencies mean my service will only start if the one it is dependent on is already running or does my service wait to start until the dependent service has started.

.net - WCF Service Hosted In A Managed Windows Service Connect Using A WCF Service Application
Jul 14, 2011i have a Windows service that is hosting a WCF service through net.tcp and this is working great. I have also created a WCF service application. I am trying to add the net.tcp service reference to the service application. Then I add it to the GAC that goes ok but if I try to RegAsm the WCF service application to allow it to be called from Server.CreateObject I get the error:
Warning: Type library exporter encountered a type that derives from a
generic class and is not marked as
[ClassInterface(ClassInterfaceType.None)]. Class interfaces cannot be
exposed for such types. Consider marking the type with
[ClassInterface(ClassInterfaceType.None)] and exposing an explicit
interface as the default interface to COM using the
ComDefaultInterface attribute.
It does not work. I have tried to call it through a class library but this does not work either as the end point is not set correctly.
Need To Regsvr32 A .dll Or Use Dependency Walker
Jun 7, 2011I just added a reference to Excel interop in my VB.net project, but when I call new WorkBook it fails with an error:Retrieving the COM class factory for component with CLSID {00020819-0000-0000-C000-000000000046} failed due to the following error: 80040154.Do I need to regsvr32 a .dll or use dependency walker to find the problem?

View 3 Replies.net - Circular Dependency Between MODEL And BLL?
Sep 1, 2011Assuming an architecture as such.MODEL > BLL > DLL
Trying to implement lazy loading in my MODEL I have run into a circular dependency between my MODEL and BLL..Basically imagine a property in my model that I want to implement as follows
Public Readonly Property ProjectCategory As ProjectCategory
Get
If Me._ProjectCategory Is Nothing Then
Me._ProjectCategory = ProjectCategoryBLL.GetProjectCategoryByID(Me._ProjectCategoryID)
End If
[Code]...
I have my MODEL, BLL and DLL in separate projects and because of the fact that my BLL references my model I can not reference my BLL from my model as this would create a circular dependency.

View 2 RepliesUnable To Find Dependency?
Oct 28, 2009I'm using Visual Studio 2008 on an XP machine. My other machine died so I had to re-install VS on a new machine. Everything worked find until I went to the new machine. Now I keep getting these 2 messages below when I go to build my solution:
Unable to find dependency 'interop.stdole' (signature ='(null)' Version='2.0.0.0') of assembly axinterop.mscomctllib.dll
Unable to find dependency 'interop.stdole' (signature ='(null)' Version='2.0.0.0') of assembly interop.mscomctllib.dll
I tried to remove the references to both .dll's and then re-add them in and that didn't work. I tried removing and re-adding stdole, and that doesn't work either. I tried installing VS on another machine, but I get the same messages there.
The only thing I noticed out of the ordinary is under Detected Dependencies, when I right-click on axinterop.mscomctllib.dll and view the dependecies, I noticed there is a yellow exclamation point in the icon for interop.stdole. I don't see any information regarding that exclamation point however.

I previously had a QuesitonClipboard.doesClipboardHaveContent function that returned true/false if there was a Object on my 'clipboard'.I'd prefer to implement a Dependency Property so I can allow this true/false value to participate in data binding.The "GetValue(dp as DependencyProperty)" method requires an object instance, which would mean that my Property CAN'T be shared!Here is what the code would look like in my perfect world... Of course, the word "Shared" before the property declaration renders this code useless.

Deployment :: Unable To Get Rid Of Project Reference / Dependency
Jun 22, 2009I have a project that I am attempting to deploy. In my project I was using a SQL Express DB and after my first build I installed on my test PC only to find that it was going to make me install SQL Express which I defiantly do not want so I decided to scrap the DB.
I excluded the DB from the project, when into the project properties pages and removed all references to SQL and system.Data, Went into the code and removed all the "Imports" statements for SQL and Data and commented out all the SQL DB code. I then tried another build and had the same results. I started looking at the files and then I realized I did not change the app.config file. I went into it and deleted out the connection string entry. I built the project again only to have the same result. I cannot seem to see what could still be referencing SQL. Isn't commented code ignored?
VS2010 Complaining About Microsoft.VisualBasic Dependency?
Feb 6, 2012I've got a .NET solution that I've just upgraded from VS2008 to VS2010. It contains three web projects and two straight VB projects. The web projects all depend on (and have a reference to) one of the VB projects called BusinessLogic.All projects are targeted at .NET 2.0, but VS2010 is raising the following build warning:
The following assembly has dependencies on a version of the .NET Framework that is higher than the target and might not load correctly during runtime causing a failure: BusinessLogic, Version=1.0.4419.22315, Culture=neutral, PublicKeyToken=null. The dependencies are: Microsoft.VisualBasic, Version=8.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a. You should either ensure that the dependent assembly is correct for the target framework, or ensure that the target framework you are addressing is that of the dependent assembly.
.net - Visual Studio 2008 Build Dependency Chain?
Feb 22, 2009I am having an issue with Visual Studio 2008 SP1. Basically, I have a .NET 3.5 solution with a client, shared and server component. While coding, all components run on the same box, but in production the server component is a standalone (remoting) service running on a separate server.
I would expect that a change to the client component would require only a rebuild of that component as there is no client/server dependency. This is in fact how it works on my work PC. However, on my personal PC and another co-worker's PC, any modification - even a simple label change on the client, requires the server component service to be stopped so that the solution can be rebuilt in its entirety. Does anyone know if there is a particular setting that controls this??
Code Organization - .NET Circular Dependency / Duplex Communication Between Projects?
Oct 16, 2011I have 2 projects
UI
Functionality
UI references Functionality to call specific functions. Functionality needs to call certain functions that operate UI. This is what I mean by Duplex communication. Is there any way to do this without causing circular dependency?Should there be 1 main project which simply does all the calling acting as a "wrapper" between UI and Functionality?

Use Windows Search Service Instead Of The Old Indexing Service To Index Files?
Jul 7, 2009In the past I had the indexing service installed on a Windows Server 2003 and used it to index files for my website.

Does this work the same way so that I only need to change the Provider name which has been "MSIDXS.1" up to now? Case true, what is the new Provider name?

View 1 RepliesService Reference Stops Working When Make Changes To WCF Service?
May 26, 2011I'm using Visual Studio 2010 and .NET3.5. I've created a WCF service application. I'm including two DLLs that contain the types I'm returning. The first method I wrote works both in WCF Test Client and also in a console application I created to test. When I move on to the next method that returns a generic list of a type. It works great in WCF Test Client, but when I update the service reference it acts as if the service is unavailable. All my objects say can't find reference, and I can no longer see it in the object browser. It's like it just disappears. I can still see it in the Service Reference folder. If I go back to the WCF app and comment out the contract and implementation of that one method it work again. I created a local class very similar to the class I'm using from the dll, and the it works. Is there something I'm missing here? Can someone point me in the right direction?
