is there a way of referencing a .NET 4.0 in a .NET 2.0 app? Whenever I try to compile and build I get an error saying:
Could not load file or assembly 'blahblahblah' or one of its dependencies. This assembly is built by a runtime newer than the currently loaded runtime and cannot be loaded.
Ive tried adding the Library as a project AND as a .DLL but still no luck. Unfortunately converting the .NET 2.0 to .NET 4.0 is not optional...
I have a Class Library Project that I'm using in another Web application project. I've noticed that this has just copied the Class Library DLL into the Bin folder of the Web Application, and also that if I make some changes to the Class Library and rebuild the project, I also have to rebuild the Web Application for the changes to take effect there.
This kind of defeats the object why I'm creating a Class Library as I'm hoping to put some generic functionality in there that will be available to a number of different web applications.
i was wondering if it was possible to:create a new WCF Service Library project build the project and reference the dll in a web application,then consume the WCF service from the web application based on that basic dll reference
View 1 RepliesI have two projects in my solution: MyApp.Domain and MyApp.WebService. MyApp.WebService is a WCF service library. I want to use some utility functions from MyApp.Domain. So in MyApp.WebService, I added a reference to MyApp.Domain. Intellisense picked it up just fine, it recognized the function I need to call. But when I build the solution, I get this error:
The type or namespace name 'Domain' does not exist in the namespace 'MyApp' (are you missing an assembly reference?) at using MyApp.Domain.Utility;
What's going wrong here?
I'm working on an internet application that has been set up as a web SITE project (I know...) in Visual Studio. I need to add additional features/functionality so have added a class library to the project and referred to it in the main web site project.
The issue now arises because I need to make use of core objects which live inside the App_Code directory in the web site project but this project doesn't appear to expose its DLL like web app/ code library projects do. Because of this I can't add a reference to the web site project in the class library to leverage the common site-wide code/objects.
I can't move the stuff out of App_Code so I'm looking for a way to refer to the website project dll from the new class library.
Is there a class library reference for the AJAX toolkit controls. I would like to see all of the properties and methods of the Accordian control.

View 3 RepliesI have an asp.net website with a reference to a class library. I can reference the class library in the aspx pages but how do I configure my site so that I can also reference the class library from a .cs file in app code?
View 1 RepliesI have several web sites, all of which use the same JavaScript library. How can I "reference" this library from each of my web sites? If I just import the library into my web site in Visual Studio, I get in trouble as soon as the library changes, because I then have to update it in all web sites manually. It would be much easier to place the library in an external folder and just reference it from my web sites. How can I do this with Visual Studio?
View 9 Replies<Application architecture>I'm developing ASP.NET Web Application by Visual Studio 2008.(.Net Framework Version = 2.0)I put followin two projetcs in the solution.a. Class library which implements all the buisiness logic for application.
(I'll call it "ClassLib" in the followin sentence)b. ASP.NET Web applicatoin which presents UI.(I'll call it "WebApp")ClassLib uses Web Service which located on other server. So, I set web reference in it. Method for url settings for this web reference is "Dynamic".
I am looking at the twitter api page http://apiwiki.twitter.com/ and I noticed that they have already built libraries that are wrappers against the twitter api. So I am thinking this is the best way to go but I am unsure which C# library I should use.
What I am trying to do is make some simple service or cmd line application that will help me automate retweeting.
So I am looking for a library that will allow me to get posts from other twitter accounts and then retweet them from another account.
I am not sure if the library can do this or not. Otherwise I was thinking of getting the RSS feed from the twiter account I want to get the twitters from parse out the new ones and use a library to retweet them on my own account.
I have not used twitter much so I am hopping someone can shed some light on this.
I am trying to call web reference "A" in an application.
The web reference "A" will then call a function in another web reference "B" through HTTPS connection (require certificate).
Then I keep getting the following error:
An unhandled exception of type 'System.Web.Services.Protocols.SoapException' occurred in System.Web.Services.dll
When you use ASP.NET web site (instead of web application model) and add reference to an assembly from local folder, Visual Studio, it seems, understands that this local assembly is also in GAC and so does NOT copy this assembly to bin folder (as it does with non-GAC assemblies), but simply adds new record in web.config file.
Why such a behaviour? Is it possible to force copy to bin folder (I need this since .dll is not on target environment)? I can add assembly to bin folder as file and it will work, but in this case bin folder contents will be in source control, which is not good.
I am working on converting a project from C# to VB and am facing this weird issue. 1 page cannot compile and I get the reference error, but the weird thing is that the compiler shows the error as coming from ASP.NET generated code. Visual Studio shows me that error is coming from my ASPX page. I cannot seem to figure out why or where this error is occuring. Also if I take the inherits attribute out I don't get the compilation error. The code in aspx page is below:

I am using VS2005, and a newbie at table adapters, DAL & BLL. I have a single dataset (in DAL) and 2 classes (in BLL) named Class1.vb and Class2.vb.
When I try to call a function from Class1 within Class2 I get the error "Reference to a non-shared member requires an object reference".
Here is a sketch of my code structure:
[Code]....
I have a Web service which, when updated on one computer with VS2008 works perfectly fine, but on another computer does not. The critical difference is the contents of the auto-generated Reference.cs.
In the correctly functioning environment, the methods have fully qualified class names, refering to classes in a class library. However, in the problem environment, the class names are unqualified and partial classes are declared near the end of the file. E.g.
[code]....
The code is under source control. Checking out to the working environment works straight away, checking out to the problem environment will only work if the reference.cs is manually edited to be like the working environments. Transferring the project manually from problem environment to the working one only requires an "Update Web Reference" to be performed to allow compilation. Both Reference.cs files claim to be auto-generated by the same tool version. The settings from the good environment have been exported to the other. No success so far...
I have a url like this:
http://www.somepage.com/main.aspx. In this page, when I click on a link it takes me to a page
http://www.somepage.com/cental.aspx?cid=200. So in the cental.aspx.cs page I did the following in the page load:
if(request.querystring["comp"].tostring() != null)
{
//do some thing [code].....
So I got an error like: object reference not set to an instance of reference.My problem is, I am using the same page. So when I go from some page, I will have "comp". but other times not. So when there is no "comp", how do I handle it in request.querystring?
I do not receive this error when I open my website application in vs 2005. When I open in vs 2008, I get this error. What gives?

Businesslogic area is imported into each of 3 pages with this line.
in my default.aspx page i have a dropdown List and a textbox with a submit button below that there are 2 listbox... and the dropdown list holds the names of the listbox
my logic here is to select an item from the dropdown list and put some text in the text box and submit the form which will add an item to the listbox selected.. but when i do this i get an error saying Object reference not set to an instance of an object. i tried to figure out the problem and found that when i remove the reference to the Site Master Page it works fine and when i undo and apply my reference back to the Site Master Page i get the same error.

Using VS2008, I noticed that in Class Project I only have a choice of adding "service reference" where as in Web Application project, I have two choices "web reference" and "service reference".
I have used web reference. How is "service reference" different from web ref? and what's the major purpose of service ref?
I am using grid view as mentioned below, it is giving me error "object reference not set", but if comment allowpaging and pagesize lines, it works. let me know whats wrong I am doing?

I'm helping out a colleague on this one so if I'm missing some details that's why.We have an asp.net 3.5 web application calling a WCF service. Originally the app used a "Web Reference" to register the service however after having some trouble and burning an incident with Microsoft their solution was to replace the "Web Reference" with a "Service Reference" to the WCF service.This is great except the problem is that when we create a Service Reference, the method signatures are different than they were when a Web Reference was used.From what I've read this may be expected, however in our case this would mean some significant changes to the application and of course it was due yesterday...so......I'm wondering two things:Is it normal/expected that method signatures will change based on the reference type?Is there a way to create the Service Reference that will generate method signatures identical to the original Web Reference?
