When I modified the project today, the version of the third-party control was upgraded, So I uninstalled the old version. After installing the new version, the new version cannot pass after being compiled again.

The error is as follows:

Compilation Error

Description:An error occurs during compilation of resources required to provide services to this request. Check the following error details and modify them as appropriate.Source code.

At the beginning, I was depressed for a long time. After troubleshooting, the old version of DLL was referenced in the original bin.

Solution:

 

Delete all DLL references under the bin folder, and then add the new DLL reference.

The aspx file header of the web project. All referenced DLL files also need to be updated,

 

Code

  1   <%  @ Page title  =  ""  Language  =  "  C #  "  Masterpagefile  =  "  ~ /Base/masterpage. Master  " Autoeventwireup  =  "  True  "  Codefile  =  "  Factory_index.aspx.cs  "  Inherits  =  "  Info_factory_index  "     %> 
  2   
  3      <%  @ Register assembly  =  "  Devexpress. Web. aspxgridview. v9.3, version = 9.3.2.0, culture = neutral, publickeytoken = 8d332da86fe888ab  "  
  4   Namespace  =  " Devexpress. Web. aspxgridview  "  Tagprefix  =  "  Dxwgv  "     %>  
  5      <%  @ Register assembly  =  " Devexpress. Web. aspxeditors. v9.3, version = 9.3.2.0, culture = neutral, publickeytoken = 8d332da86fe888ab  "  
  6   Namespace  =  "  Devexpress. Web. aspxeditors  "  Tagprefix  =  "  Dxe  "     %> 
  7   .........
  8   ......... 

The Web. config configuration file also needs to be updated.

It is really troublesome!
