"System.Web.Extensions, version=1.0.61025.0, Culture=neutral, publickeytoken=31bf3856ad364e35"

Parser error message: Failed to load file or assembly "System.Web.Extensions, version=1.0.61025.0, culture=neutral, publickeytoken=31bf3856ad364e35" Or one of its dependencies. The found assembly manifest definition does not match the assembly reference. (Exception from hresult:0x80131040)

Solution:

Download someone else's Ajax source code, run this error

The reason is that the file or assembly could not be loaded system.web.extensions

System.Web.Extensions, version=1.0.61025.0, culture=neutral, publickeytoken=31bf3856ad364e35 "or one of its dependencies. The system could not find the specified file.

The obvious error is that the assembly is missing.

Solution:

1, if your program is running on the server you can control, then install ASP.net ajax on the line, this is System.Web.Extensions and other DLLs as the GAC deployment;

In Baidu input (asp.net AJAX 1.0 download) You can find the software to download

2, if your program is running on a virtual host (no right to install the program), then you need to put System.Web.Extensions.dll and System.Web.Extensions.Design.dll

(usually in C:\Program Files\Microsoft Asp.net\asp.net 2.0 AJAX Extensions\ v1.0.61025 directory) 2 DLLs are copied to the bin directory of your Web program, which is an application-level deployment.

Also note that you want to check the code in Web.config

<assemblies>
<add assembly=&quot; System.Web.Extensions, version=1.0.61025.0, Culture=neutral, publickeytoken=31bf3856ad364e35&quot;/>
</assemblies>

<controls>
<add tagprefix=&quot;atlas&quot; namespace=&quot; system.web.ui&quot; assembly=&quot; System.Web.Extensions, version=1.0.61025.0, Culture=neutral, publickeytoken=31bf3856ad364e35&quot;/>
</controls>

Mine is not controlled on the server, so after installing this ASP.net Ajax 1.0, then C:\Program Files\Microsoft Asp.net\asp.net 2.0 Ajax Extensions\ The System.Web.Extensions.dll and System.Web.Extensions.Design.dll under the v1.0.61025 directory are OK when copied to the Bin directory. The code in the Web.config is not checked, because the operation was successful, and it was not considered so much. 51aspx Forums found in the solution.
