Microsoft.ReportViewer.Common Version=12.0.0.0

问题:

I'm getting the following exception in my Windows Service Application:

System.IO.FileNotFoundException: Could not load file or assembly 'Microsoft.ReportViewer.Common, Version=12.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91' or one of its dependencies. The system cannot find the file specified.

I cannot find a download url for version 12 and setting the files to "Include" and "Prequisite (Auto)" does not solve the problem in this Windows Service Application, although it works fine in my WinForms Application and results in the appropriate files being included and referenced along with all other requisite .DLLs.

Can someone either help me get this Windows Service Application to include the files, or lead me to a download link that will install Version 12 in the GAC?

回答1:

Version 12 of the ReportViewer bits is referred to as Microsoft Report Viewer 2015 Runtime and can downloaded for installation from the following link:

UPDATE:

The ReportViewer bits are also available as a NUGET package: https://www.nuget.org/packages/Microsoft.ReportViewer.Runtime.Common/12.0.2402.15

Install-Package Microsoft.ReportViewer.Runtime.Common

I worked on this issue for a few days. Installed all packages, modified web.config and still had the same problem. I finally removed

<assemblies>
<add assembly="Microsoft.ReportViewer.Common, Version=12.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91" />
</assemblies>

from the web.config and it worked. No exactly sure why it didn't work with the tags in the web.config file. My guess there is a conflict with the GAC and the BIN folder.

Here is my web.config file:

<?xml version="1.0"?>
<configuration>
  <system.web>
    <compilation debug="true" targetFramework="4.5" />
    <httpRuntime targetFramework="4.5" />
    <httpHandlers>
      <add verb="*" path="Reserved.ReportViewerWebControl.axd" type="Microsoft.Reporting.WebForms.HttpHandler, Microsoft.ReportViewer.WebForms, Version=12.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91" />     
    </httpHandlers>    
  </system.web>
  <system.webServer>
    <validation validateIntegratedModeConfiguration="false" />
    <handlers>
      <add name="ReportViewerWebControlHandler" preCondition="integratedMode" verb="*" path="Reserved.ReportViewerWebControl.axd" type="Microsoft.Reporting.WebForms.HttpHandler, Microsoft.ReportViewer.WebForms, Version=12.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91" />      
    </handlers>
  </system.webServer>
</configuration>
