Is Calling A .net 4.0 Assembly Possible From .net 2.0
Oct 29, 2010
Can anyone tell me if its possible for a site or application that is running against .net 2.0 to call an assembly that was compiled using the 4.0 framework?
I always thought that this was possible, however when I try and add the reference to Visual Studio, I get an error saying that its not happy with the difference in versions.
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 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?
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?
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've a question I don't know if this is possible or not. I've tried a lot of things till now but could not accomplish on what I wanted to do.
What I want to do is call a web page from another page and some how execute either the page load event or page init event and get the result of the page in the first page.
Page A calls page B. Page B has static text and a label which is being set in page load event.
Page B - Code behind
[Code]....
Page B -- HTML code
[Code]....
Till now what I've tried is using the code below from page A. But this code just returns the Html code and nothing else.
How to know which application is using an Assembly in GAC? I want to remove unwanted assemblies from GAC but it is not getting removed as it is used by some other application.
I have a shared assembly, in which it has 4 versions and I have placed it in GAC location. I have to Use the 2nd version of the assembly. Please let me know how should i indicate the 2nd version of the assembly? Which one tell to CLR to find exact 2nd version?
I created this website and it work fine on local machine but when i upload it to remote server then it throws error that it cant find assembly....
The assembly is not in my Bin folder and i can not find it in my machine or at least don't know where to look.

I created a custom virtual path provider and build provider and was wondering if it was possible to somehow specify the name of the assembly that get's generated, rather then letting asp.net come up with a name?
I am using asp.net with C#. I have a application deployed on the server [published], now I want to see the code for that website, As far as I know I can read assembly to see the code.
I need to compile a class library (DLL) from an ASP.NET source. Now when I try to build it says this:
The type 'System.ComponentModel.ISupportInitialize' is defined in an assembly that is not referenced. You must add a reference to assembly 'System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'.
Now I know that I have to put it in the web.config file. But there is no web.config file it's just the source of the dll that needs to be compiled.
I need to know which version of the report viewer control is used on a web server. If I can find it without asking it would be nice.Is there a way, by code, to find out which version of the assembly is used on the server?
I've installed MVC3 on VS2010 Professional 4 times now and the default web project complains because it's missing System.Web.Mvc.I used the PI twice, and manually uninstalled/installed another two times.I can't add a .NET reference to MVC because it's not there. I downloaded and compiled the binaries, but the compiler fails because the gac thinks there are two definitions for MVC. I can't find MVC, though.There are no problems with I install MVC2.How can I install MVC3 so it appears in my project References folker, or in the .NET gac?

I'm starting a new ASP.NET MVC project, and I decided to put my controllers in a different assembly. Evertyhing works fine, but I have hit a problem: I created a new area in my MVC Project, called Administration. I have an AdminController Class in my seperate assembly which is supposed to return views from my Admin area, but everytime it tries to return a view, it looks for it in the wrong place (~/Admin/SomeView.cshtml Instead of ~/Administration/Admin/SomeView.cshtml) How can I tell the controller to look for views in the wanted area?
Ajax control toolkits old version's Calender working properly in IE 6 but this version dosn't support asynchronous file uploader control, But the version available for .net framework 3.5 has issues like its making hang the explorer but it has async file uploader. one of my asp.net application targeting .net frame work 3.5 using vs2008 need both options. use both controls(both assemblies) in the same projects.Client need to access application through IE6 only
How can i access both assemblies in the same project ?
Does anyone know a good way to embed user controls inside an assenbly so they can be reused across projects. I am not looking to create custom web controls. I have ascx files from different projects which I want to centrally use.

But the assembly it's talking about already shows in my GAC
