RDLC deployment RDLC deployment to IIS missing DLL assemblies

1. Error: opening the RDLC report after deploying to the server from the VS build site prompts for a missing DLL assembly.

Generally, the following files are missing

1. Microsoft.ReportViewer.Common.dll

2. Microsoft.ReportViewer.WebForms.dll

3. Microsoft.ReportViewer.ProcessingObjectModel.dll

2. Cause:vs generates the site without outputting the assembly required by the RDLC report to the bin directory.

3. Workaround: Copy from the development computer to the Web site Bin directory on the server.

4. Detailed steps

4.1: Because some DLL assembly is hidden in the computer, the whole search is not found. So use the following method

4.1: Open cmd Enter the following code

Copy files with path C:\Windows\assembly\GAC_MSIL to file folder in C drive
xcopy C:\Windows\assembly\GAC_MSIL c:\\file/e

4.2: At this point, CMD will display the following prompt (we can enter D)

　　　　

4.3: You can then search for your missing DLL assembly under this folder
