I have created an application which runs fine in VS2010.Now i am trying to host that application using inetmgr.When i try to browse the page from inetmgr content view then i get the "Parser Error Message: Could not load file or assembly 'System.Web, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified".If i browse the page from VS i am able to do it.I am not able to host the app. may be the reason is the above stated error.
I've just got an error message that was somewhat unexpected:

I've got an ASP.NET website that has abotu 10 projects makign it up which are compiled into DLLS and in the bin directory. ReportingContents is one of these projects. In the past I have had success in copying over a new version of the files (dll, pdb and xml) to the bin directory and recycled the app pool and it just picks up the new version on its own. This time I thought "I shouldn't have a debug version on the site" so I built as release and just copied up the dll and xml files and asked our deployment people to remove the pdb.When I was told it was all done I tried to access the site and got the above error message.The thing that surprises me is that the assembly it mentions is "Delete ReportingContents" and I don't know where the "Delete " might have come from in there.
I am getting this message on my Page element. However my project references C:Program FilesMicrosoft ASP.NETASP.NET MVC 2AssembliesSystem.Web.Mvc.dllwhich is Version 2.0.0.0Furthermore my Web.config contains

Things of note:
A simple IIS Reset fixes the issue. We had the same code running on a single webserver with no problems. We then moved the site to two new, load balanced (using sticky sessions) webservers (all three Windows Server 2003 R2 Standard Edition SP1). Now each of the load balanced webservers throw this exception about once a week just out of the blue.The only major difference I can think of, is I've installed the 4.0 .NET framework on the load balanced servers. The website is still running under ASP.NET 2.0 so I don't see how this would be an issue I've configured the indexing service to not search the "Temporary ASP.NET Files" folder, but it didn't help. We use the Microsoft.Practices.EnterpriseLibrary.Data dll everywhere on our site. Almost every single page uses our logic dll which in turn utilizes the EnterpriseLibrary dlls. While the errors where happening once, I even looked to see what processes were locking the dll in the "Temporary ASP.NET Files" folder, and it wasn't any different than the locks on the server that was working fine. Once the error starts, it errors every single time until an iisreset is performed.
I've tried deploying my asp.net app to a new server and I get this error:
Could not load file or assembly 'System.Web.Entity, Version=3.5.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' or one of its dependencies. The system cannot find the file specified.
Sure enough, System.Web.Entity isn't found in C:WindowsAssembly. However, the server has MS .NET Framework 3.5 installed and also MS ASP.NET 2.0 AJAX Extensions 1.0. Is this something I need to deploy with my app, or something I need to be installed on the server? It's not my own server so xcopy deployment within my app folder would be much better if that's possible.

I am developing the Windows Live@edu SSO integration with asp.net custom code.It uses the DLL called "System.Management.Automation" for executing Windows powershell v2.0 commands for connecting Outlook Live Apps.It works fine in localhost,but during deployment in Windows server 2008 , it shows error called

I had web application developed in VS 2005 + Sql server 2005 + Ajax 1.0 Extension . (Developed in Windows Server 2005) Now i am migrating to VS 2008.(Windows Server 2008 + Sql server 2008)
After opening and compile my Existing application in VS 2008,i am getting error.
Errors :-
Unable to load file or assembly 'System.web.Extenstions'' version=1.0.61025. (I think it because of AJAX Extension version.So i installed AJAX Extension 1.0 but it will give me ambiguous error so i uninstalled.I am added reference for version=3.5.0 but again unsuccessful.) What i will do now? Also i used 'Microsoft.SqlServer.SmoEnum', Version=9.0.242.0 in VS 2005. (Are i have to change it to version=10.0.0.0? by adding reference to new version.) I also used crystal report.(Is there is anything to do with it?)
I'm working on my ASP Application 2.0 framework with AJAX Extension 1.0 installed on my pc. I'm getting an error on my CrystalReportViewer:Could not load file or assembly 'System.Web.Extensions, Version=2.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)" I already tried some solutions I found in google but it's still im getting the error.: [URL]Below are the codes for my web.config
I've add MSChart to a webpage and I'm also using a Survey page I got from 4GuysFromRolla (http://www.4guysfromrolla.com/articles/061604-1.aspx). Both work on my development machine but when I move them to my hosting site there are issues.
With MSChart page the chart is not displayed although it's included the Page Source code: src="/ClubInformationTracking/ChartImg.axd?i=chart_3d90c53b0f844807a2491a1d79a636a1_0.png&g=75fecf0f14cf4121b623691d383263aa" alt="" style="height:300px;width:700px;border-width:0px;" />
And when I try to open the Survey page I get this:Parser Error Message: Could not load file or assembly 'sstchur.web.survey' or one of its dependencies. The system cannot find the file specified.
Assembly Load Trace: The following information can be helpful to determine why the assembly 'sstchur.web.survey' could not be loaded.
WRN: Assembly binding logging is turned OFF.To enable assembly bind failure logging, set the registry value [HKLMSoftwareMicrosoftFusion!EnableLog] (DWORD) to 1.
Note: There is some performance penalty associated with assembly bind failure logging.To turn this feature off, remove the registry value [HKLMSoftwareMicrosoftFusion!EnableLog].
The Hosting site is using Version 4.0 and the dll needed for the survey is in the BIN directory.
When I moved my files to the hosting site I had to change every instance when I referred to a file from: "~/FileName" To "FileName"
I've tried all of the "fixes" I could find for the MSChart that involved changes to the web.config file but because of the error messages associated with the Survey page I'm guessing this is the issue.
