Web Forms :: Referring An Assembly In Project / Without Adding Assembly Reference, It Still Accepting And Running Code?
Jul 5, 2010
Before using any class in your website project/page we have to add it's assembly reference to our project. Right?
Now, when I am using SmtpClient class from System.Net assembly after adding the System.Net.Mail namespace in namespace node of application's web.config file but without adding assembly reference to the project, it still accepting and running the code. Why?
I enquired the machine's web.config file located at C:WINDOWSMicrosoft.NETFrameworkv2.0.50727CONFIG but didnt find assembly reference for System.Net there also.
So bit confused how it is working and where the assembly reference has been added and how?

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 was wondering if visual studio 2010 can be used as an assembly editor too????if yes where do i have to go to create a first blank page for an assembly project?
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:
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 have recently discovered that I am affected by this bug http://www.mail-archive.com/mono-bugs@lists.ximian.com/msg71515.html
Well,at http://www.mail-archive.com/mono-bugs@lists.ximian.com/msg71529.html they say the work around is to create a global policy assembly and redirect the assemblies that way since it is not read from the web.config.
How do you actually do what they describe there? There is a huge documentation gap in that area with Mono.Also,I can't just recompile the assembly to use the new Mono assembly versions because the assembly is closed source.(but it does work with Mono.)
I have adeed a dll file on my project and it's working fine with local system. but when i uploaded it on hosting webspace it's displaying error. "assembly refference is missing" i have alreday added bin folder there. So how to add bin folder on hosting spaces.
My project references Library1.dll and Library2.dll. Library2.dll has a dependency on Library1.dll, but it was compiled to reference it by a different name, Library1.Net40.dll. there an nice way tell my application to redirect all references for Library1.Net40.dll to resolve to Library1.dll? Maybe something similar to the way you can redirect versions using a <bindingRedirect> I've got a solution that handles the AppDomain.AssemblyResolve event, but it's a bit of a hack and am hoping there's a better way to do this.
I need to add reference to 'System.XML.dll' assembly into web.config (in order to try solution for problem, mentioned here: Problem with Extension method: IXmlLineInfo).I've tried to add the following line into "assemblies" section:
I just want to create Shared Assembly and use that assembly in our application.I am using VS 2005.
Step 1
I am trying to build a dll.
Create class library project <TestDllHell>.
Under that project add CalculationArea.cs file.
[Code]....
Then TestDllHell.dll add into GAC successfully.
Now I want to use it in my Website project so did the following steps but unable to view that dll in .Net Reference List Box.
•I go for Run regedit to edit the Windows Registry.
•Navigate to the HKEY_LOCAL_MACHINESOFTWAREMicrosoft.NETFrameworkAssemblyFolders key.
•Right click on the AssemblyFolders key, then select New > Key. Enter the name of your assembly (without the .dll extension).
•Double click on the key's (Default) value. The Edit String dialog will appear. Enter the full path of the folder where your assembly resides. Note that all assemblies in that folder will appear in the Visual Studio list.
•IMPORTANT! You must exit and restart Visual Studio to see your assembly in the Add Reference dialog.
My question is that
How can I get that dll in my add reference assembly List .Net section?
And if I modify that dll(TestDllHell.dll) then again register in GAC then version will be different,So how can I told my client application that which dll you choose?
I wasnt sure where this question best belongs, in the end I figured this was the best place...
Say I have a utility dll that i might use in either a windows console application or in an asp.net web application - how can I programatically find whether it is running on web or windows, from within the dll?
I feel like this is something I should know by now, maybe some property of AppDomain.CurrentDomain, or Environment, but I just can't find it.
The reason I'm asking is because I'm playing around with nHibernate for asp and I seem to need different session handling when running in asp.net, compared to when i'm running integration tests. So if someone knows how i can solve this without programatically checking the context of the application, then that'd be great too.
I downloaded the trial version of abcpdf, which is absolutely fantastic!
Anyway, real simple, you just need to reference the .dll and off you go...
So, I got my code working, but when I moved to production server I hit a wall.
It definitely has to do with the .dll because when I comment out the pdf sub routine, the code executes and completes all other tasks. When I uncomment, It's not working.
The trouble is, on my server I don't have the full version of VS, so I am unable to add a reference, which I presume takes care of the web.config settings? I manually dropped the .dll into the bin folder and I added the assembly line into web.config, but, as I don't have the above, I am not sure if the token key is correct.
To test this, I uploaded the working .dll file to my server, which I assumed the key is associated with, but still the same.
how to either get the correct key and/or how to reference an assembly manually? Is there something I have missed?
I posted a question about how to save the result of an SQL command to a variable and was told that the execute scalar method should be used, however I can't use it, I'm using the System.Data.SQLClient reference but still not finding it

I have trouble getting a custom ObjectDataSource for an asp:ListView control to work. I have the class for the DataSource in the App_Code directory of the web application (as required by the asp:ListView control).
using System; using System.Collections.Generic; using System.ComponentModel; using System.Configuration; using System.Data; using System.Data.Common; using System.Web; using System.DirectoryServices;........
As soon as I add using System.DirectoryServices; the page crashes with this message:
Compiler Error Message: CS0234: The type or namespace name 'DirectoryServices' does not exist in the namespace 'System' (are you missing an assembly reference?) Without the usage of System.DirectoryServices the page loads without problems.
The reference is there, it is working in classes outside the App_Code directory.
If I have a reference in my project to System.Data.Linq in an MVC application compiled against 3.5 I can use Linq to SQL generated entity objects in my views and access the foreign key entity sets. If I try and do the same thing in 4.0 I get the error messageCompiler Error Message: CS0012: The type 'System.Data.Linq.EntitySet`1<T0>' is defined in an assembly that is not referenced. You must add a reference to assembly 'System.Data.Linq, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'.
I recently moved my class based on IUnityResolver from the mvc3 project (where I tested it), to a class library (which references all five Unity dll's. I'm getting the following error, why? Are there other dependencies for which I am unaware?The type or namespace name 'IUnityContainer'...are you missing an assembly or reference?
I have an ASP.NET project and I want to use some AjaxToolKit Extenders on my pages.
The site is created in VS2010, set to Framework 4.0.
This is what I did:
1) Add reference "AjaxToolKit.dll" to my project.
2) Add to the toolbar the same file for the controls
3) Add "ToolkitScriptManager" to the page source.
This adds the declaration to the source as well.
Right after this I get the following error:
Reference required to assembly 'System.Web.Extensions, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' containing the base class 'System.Web.UI.ScriptManager'. Add one to your project.
why the assembly information would be missing for a project in VS 2010? There is an 'AssemblyInfo.vb' filed located in the 'My Project' folder with values provided for the title, product, etc and GUID. However if I open the 'Assembly Information...' dialog in the 'Application' tab of the properties for the project all the fields are blank.
I'm having trouble moving a website from one server to another. It seems to be a problem loading multiple versions of System.Web.Extensions. The code uses version 3.5 in most places but a third party control appears to be needing version 1.0.6. I didn't think this was possible but it appears to be working in it's current situation.
Is there a way I can use the GAC version of System.Web.Extensions for the site but import a dll of version 1.0.6 just for these controls?
I have to admit first, that for the last few years, I've been mostly an MVP guy versus MVC. However, how I used to implement MVP is very similar to how MVC 2 is now implemented. I only have one issue with it...When I used to create MVP apps, I could put all my logic (presenters, models) into separate assemblies/projects in the solution and my views into the main web app. This allows me to change the UI (i.e. the web based UI) to something else like a smart client or Silverlight or whatever and still have everything just work. With MVC 2, everything is all in the same project: controllers, views, models. Areas looked like a good start, but ultimately, not what I was looking for.So, here's my question... How do I move the controllers and models out of the web project and into their own projects and still have everything work? A good, simple example would be the default MVC 2 web application template. When you open a new (non-empty) MVC web application, it creates a basic site for you. From there, how could I move the controllers and models in separate projects and still have everything just work? I can't seem to find anything on this anywhere else which has brought me here
