Resolving Could not load System.ServiceModel error in Miscellaneous

1 min read

This issue may arise if you have installed Syncfusion Essential Studio with all the product components including Silverlight in the IIS-configured machine. This is a known issue, and it will be fixed starting from version 11.x.x.xx of Syncfusion Essential Studio.

As a workaround, you can resolve it by running Aspnet_regiis.exe with the below arguments to re-register the correct version of ASP.NET in the IIS web server.

1. Open the command prompt with administrative privileges and navigate to the the Aspnet_regiis.exe file, which can be found in one of the following locations:

%windir%\Microsoft.NET\Framework\v4.0.30319
%windir%\Microsoft.NET\Framework64\v4.0.30319 (on a 64-bit computer)

2. Run Aspnet_regiis.exe with the following arguments: aspnet_regiis.exe /iru

3. Refresh the IIS web server or run the iisreset command in admin mode and restart the Syncfusion dashboard.
