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?

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'm getting following warning
Assembly generation -- Referenced assembly 'System.Web.dll' targets a different processor
What does this mean and how do I fix this?
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 have strange problem with missing assembly of my application after IIS restart. My application is installed correctly to IIS 7.5 (windows 7) and works fineAfterwards I make a restart of IIS serverNow my application is not working properly, some classes (assemblies) are missing. I've insterted a code to my application that writes all avaible assemblies into my log file (see code below ) and really a few assemblies are missing[Code]....
Restart of IIS or even restart of windows is not enoughThe workaround is to make some change in web.config or to rewrite some *.dll by the same dll library (in order to force IIS to reload whole application)afterwards it works fine again (till next restart of IIS) for better understanding I've recorded a video for you [URL] Do you have any idea how to solve it? or what what to check? (My application is based on ASP.NET and I'm using ported version of Jade framework (framework originally created in Java).) This problem is related to another problem on this forum [URL]
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.

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 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?

View 1 RepliesI 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.
tell me the way to solved my problem to looking for a long time.
My System Info:
OS: Windows 7 - Ultimate - 64bit
VS: Visual Studio 2008 - Professional (and problem with my VS2010 installed)
Problem:
I have a small project and build it to library .dll file with some function util.
From an other website (with diffirence solution). I added reference the .dll before to website.
In website, I declaration to using the function in library (dll file before). But I found error:
Error 1 Type 'LibraryName' is not defined.
And in VS2010 the problem is same.
But, run website on an other computer, it work normally.
In development I installed "ODAC Entity Framework and LINQ Beta (11.2.0.2.30)" so that we could have a 32 bit version of Oracle.DataAccess for ODP.Net. In Visual Studio 2010 (on Windows Server 2008 R2) I made a reference to:
C:Oracleodp.netin4Oracle.DataAccess.dll.This adds: <add assembly="Oracle.DataAccess, Version=4.112.2.30, Culture=neutral, PublicKeyToken=89B483F429C47342" /> to the assembly in the web.config.
We set the AppPool to Enable 32 bit applications and everything works great. For anyone who doesn't know the story here, we do this because Visual Studio 2010 runs in 32 bit so you need the 32 bit ODAC/ODP.net components to get a development environment running. I then publish the files and move to a 64 bit machine.
I downloaded the "ODAC112021Xcopy_x64.zip" Then ran: install.bat odp.net4 c:oracle odac and I can see the Oracle.DataAccess.dll file at: C:Oracleodp.netin4Oracle.DataAccess.dll. Then added c:oracle;c:oraclein;c:oraclein4 to the System Path.
At this point I would think I just replace the version and PulbicKeyToken in: <add assembly="Oracle.DataAccess, Version=4.112.2.30, Culture=neutral, PublicKeyToken=89B483F429C47342" />
on production to the versioin installed on prod. So first thing I do is just remove that line on production to see what error I will get. And I still get the same error:
System.IO.FileLoadException: Could not load file or assembly 'Oracle.DataAccess, Version=4.112.2.30, Culture=neutral, PublicKeyToken=89b483f429c47342' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)
Actually this is if I move the new dll into the applicaitons bin directory. If I remove the dll from the directory I get: Could not load file or assembly 'Oracle.DataAccess, Version=4.112.2.0, Culture=neutral, PublicKeyToken=89b483f429c47342' or one of its dependencies. The system cannot find the file specified.
So I put the line back in.
I right click on on the new Oracle.DataAccess.dll and click properties. In the details tab I see verion is 4.112.2.0. That makes sense. The 64 bit XCopy version is an earlier build then the 32 bit Beta that comes with Entity Framework and LINQ(Version=4.112.2.30).
So on production I change the Version attribute to: 4.112.2.0. But now I get the same error: System.IO.FileLoadException: Could not load file or assembly 'Oracle.DataAccess, Version=4.112.2.30, Culture=neutral, PublicKeyToken=89b483f429c47342' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)
(This is with the new dll back in the web app's bin directory as is the rest of the thread).
It's still looking for the same version of the assembly. Why is it doing that? The web.config has a connection string with the ODP.Net provider type (Oracle.DataAccess.Client). Which would take from the assembly reference. It should not care what the version number is. Could there be something in code somewhere that is specifically looking for the old dev box version? Just what is the way to make it use the new assembly?
I would think the system would just know where to find the new dll. Just as in development the add reference dialog knew that the dll was in c:oracle... rather then c:program files(x86)... like out-of-the-box Microsoft assemblies.
Currently, when I want to use Microsoft Chart Controls on a website, I need to add the following onto every aspx page where I want to use it:
<%@ Register Assembly="System.Web.DataVisualization, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"
Namespace="System.Web.UI.DataVisualization.Charting" TagPrefix="asp" %>
Is there any way to move this to the web.config file, so that I don't have to put it on every page ?
