Unable To Load File Or Assembly 'System.web.Extensions' Version=1.0.61025 While Migrating VS 2008
Jan 28, 2011
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.

I am getting this error that is related to ReportsViewer. I need to eliminate all references to this library. So where do I need to start deleting the references?

I have a .net web application hosted in Sharepoint 2007. Recently I added a page to launch an application(.exe) from the code behind of a .aspx page. The applicatoin is launched when I test it on my desktop(without Sharepoint). When I deploy the .aspx page and the dll to the Sharpoint, I get an error "Could not load file or assembly 'CheckService, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. The system cannot find the file specified.
I'm working on a project that accesses the Exchange Server. Before I replaced the project to a server, everything went fine. But now I'm getting this error.
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've been using a particular version of a PDF library (PdfSharp), with the dll file in the bin directory (bin/PdfSharp.dll). I use this to prepare, combine, split, and otherwise manipulate PDF files, both those that come from outside my app and those I generate using ReportViewer.
Today I saw there was a new version of the library and naively dropped the new .dll into the bin folder, replacing the old one (I rarely have need to mess with the 2 or 3 dlls in my bin folder and it's been 2 years since I set them up so I wasn't really sure how to proceed and didn't take the time to think too much about it). The PDF generation no longer worked, so I deleted the newer .dll and replaced it with the older one (I have copies in backups, the production server, etc).
Now, although I've confirmed that the dll in the bin folder is the older version (file Properties show correct older version number, file size is older file size, etc), and although the application works correctly, including those parts that call on the library, I can no longer access the data sources for my RDLC files -- when I open an RDLC file in the editor and choose Report->Data Sources, I get this error:
Could not load file or assembly 'PdfSharp, Version=1.2.1269.0, Culture=neutral, PublicKeyToken=f94615aa0424f9eb' or one of its dependencies. The system cannot find the file specified.
I am mystified: I don't understand the connection between a report's data source and this library; I know that the correct version (1.2.1269.0) is in binPdfSharp.dll; and I can find no references to any version of PdfSharp in any file in my application, other than the code that actually calls it (ie, there are no references to it in web.config or the .rdlc files or the dataset .xsd files). I've also been through the registry and find no references to the new version. I've tried deleting the dll and re-adding it using "Add Reference...", and I've tried "Update Reference", all to no avail.

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.
