Hi n/a,
Thanks for contacting Syncfusion Support.
We were unable to reproduce this reported issue. The Syncfusion assembly references added successfully in the project and we could able to run the Syncfusion ASP.NET MVC project successfully from our end.
This issue may raise in specific machine environment. So, please provide the Installinfo.xml file to reproduce the issue from our end. You can get it from below mentioned location.
Location: {Essential Studio Build Installed location}\{Build Version}\Utilities\InstallInfoGenerator\InstallInfo.xml
For Example: C:\Program Files (x86)\Syncfusion\Essential Studio\<Essential Studio Version>\Utilities\InstallInfoGenerator\InstallInfo.xml
Mathi.
