Visual Studio :: Can't Add A Reference To A DLL
Jan 27, 2010
Has anyone ever experience problems adding a reference to a DLL in Visual Studio? I have a website that I copied from our development server and placed it on a virutual pc on my local machine. I updated all the references to all the DLLs. However, when I open the property pages window, the only references I see are ones to the GAC. When I try to add a reference to a DLL it adds it to the bin directory, but it will not show in the properties pages and the reference is not resolved and I still get the error that the type is not defined. I've tried deleting the DLL and adding it again, but nothing seems to work.

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.

1. Is there a reason why someone would want to add a reference to an assembly (e.g. System.Drawing) but not add the Using statement? Seems that if you add a reference, you should add the Using statement automatically, but maybe not always?
2. Correct me if I'm wrong, the only benefit of adding a "Using" statement at the top of your file, is to bring into scope an assembly and not have to fully type the class name? So if I have a Using System.Drawing, I can type in
string = Color.Tomato.ToString(); instead of string = System.Drawing.Color.Tomato.ToString();

I had a web reference set in my VS2008 ASP.NET project, but due to some source control weirdness it is no longer listed in the project. I have the set of files in the Web References folder under my project. There's a .wsdl, .disco and several .datasource files. Is there any way to re-add this web reference through the existing files rather than using the "Add Web Reference" dialog?

I am using VS2010. When I am building a release for a WinForms Applicaiton, I can see some .xml files relevant to project in the bin elease folder. The .dll (third party component) has been referenced in the References folder of the project for eg. Rebex.Net.Ftp and in the properties window the Source Path is
C:Program FilesRebexFile Transfer Pack for .NET 4.0FTP SSL for .NET 4.0inRebex.Net.Ftp.dll In the above mentioned source path directory there is an Rebex.Net.Ftp.xml which gets pulled across to the release folder as well. I couldn't really get my head around where this can be referenced so that it puts this .xml file in the release folder of the project when I do a build?
My main problem is, when I created a setup project for this application, I can't get this file included in the installation pack (after installing the .msi file). I get the Rebex.Net.Ftp.dll but not Rebex.Net.Ftp.xml file. I tried all the options in the Project Output except including the "Source files" which I dont want to. how to include the .xml files in the setup installation pack, ie., if there are properties I am forgetting to set or something like that?

I'm aware of the following two different types of web projects in Visual Studio 2008:Website projectWeb application projectA web application project can reference a signed assembly as long as the web application's assembly is also signed with the same key. However, this doesn't work with the website project because there is no place to sign an assembly. I think this is because the assembly is compiled dynamically on the server?
Anyway, is it possible to get the website project working with this signed assembly? Or will I have to convert this website project into a web application project?Edit:The following situation has required me to ask for clarification in this matter:I have a class library that is being referenced by several other projects in my solution in Visual Studio. One of the projects is a windows application that will be deployed to specific external users. In order to make sure that the application is using the correct assembly and to also prevent others from using the assembly (I am aware of the limitations with respect to its effectiveness), all assemblies have been signed and all the classes in the library are declared as Friend (internal).
The website project doesn't seem to have a way for me to sign its assembly and I get the following message when attempting to use anything from the library: "CLASS is not assessable in this context because it is 'Friend'", which is to be expected.The following attributes are inside the AssemblyInfo.vb file in my class library project:
<Assembly: InternalsVisibleTo("OtherProject1, PublicKey=AAA...")>
<Assembly: InternalsVisibleTo("OtherProject2, PublicKey=AAA...")>
...
My Conclusion:Looks like the cleanest way to do this would be to convert the website into a web application but this would require a bit of time to do since our site is pretty fleshed out already and as pointed out in other discussions, can be quite a pain to do. Going forward, I think creating a web application in the first place may have been a better idea and much more flexible for future development.

I'm trying to reference a color value, which is stored in a file called Rsource.resx in the App_GlobalResources directory.
In vs 2008, I used to be able to use a line like this:
[Code]....
Now, in VS 2010, that no longer works.
I found a VS 2010 example that suggests I could try
[Code]....
or
<asp:Label ID="Label1" runat="server"
Text="test", BackColor="Resources.Webresources.sunlight",Visible="false"></asp:Label>
These examples both generate an error that the server tag is not well formed. I'm fairly new to this, so I think my error will be obvious to someone...
What would be the correct way to reference the color value in this case?

I have an annoying problem when I'm developing in Visual Studio 2010. I am using an UpdatePanel in my .ascx file like this:
<asp:updatepanel id="upStuff" runat="server">....</asp:updatepanel>
in my control.ascx.designer.cs, the update panel is being defined like this:
protected global::System.Web.UI.WebControls.WebParts.updatepanel upSettings;
this produces the error:
"The type or namespace name 'updatepanel' does not exist in the namespace 'System.Web.UI.WebControls.WebParts' (are you missing an assembly reference?)"
The actual namespace should be System.Web.UI.UpdatePanel. When I go directly into the designer.cs file and change it, it works. However, every time I go back into editing control.ascx and save, Visual Studio always changes it back to system.Web.UI.WebControls.Webparts.updatepanel. I'm not sure what is causing this. Is it how I should be referencing namespaces and classes in my project? I'm using .NET 3.5.

I am trying to add a web reference to my project in Visual Studio 2010 that points to PayPal's Sandbox service.
The address is [URL]
Although VS finds it using the Add Web Reference dialog box, when I press the Add Reference button I get the following error and it fails:
Failed to add Web Reference 'com.paypal.sandbox.www'.
Error: Access to the path 'C:Documents and SettingsMyNameLocal SettingsTempPayPalSvc.wsdl' is denied.
Even if I attempt this using http instead of https it still fails with the same error.

I 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?

I installed a few days ago VS2010 Ultimate (RTM). I made sure that MVC 2 Tools for VS2010 are installed and indeed when I open the add a new project dialog I find the MVC 2 templates. The strange thing is that when I add a class library project and then want to add reference to System.Web.Mvc assembly I find that this assembly isn't in the list. I made sure that the project's target is .NET 4 (and not client profile).
Eventually I solved it by browsing to the assembly under MVC2's folder in Program Files. I don't think that's the best way to solve it, but I don't see another solution. It seems like everything is properly installed and for some reason the MVC2 assembly isn't in that long reference list in C:Program FilesReference AssembliesMicrosoftFramework.NETFrameworkv4.0.

Just to test, I created a blank website and a blank web site project.
When I added a referece to web site by doing right click and add reference it added the dll inside a BIN folder but on ther other hand when I did the same for a web site project it created a reference folder for me and then added the dll under the reference folder.
