How to resolve "Could not load file or assembly" error?

Problem

Could not load file or assembly 'Syncfusion.EJ, Version=14.2451.0.26, Culture=neutral, PublicKeyToken= 3d67ed1f87d44c89' or one of its dependencies. The system cannot find the file specified” after running the project.

Reason

Reason for the error is Syncfusion.EJ assembly is not referenced properly in the sample.

Solution

You have to refer the dll’s that are installed in the system and the assembly details can be found from the following installed location.

“<Installed Location>\Syncfusion\Essential Studio\14.2.0.26\precompiledassemblies”

After adding the Syncfusion assemblies you have to update the version of the web.config file that is located under the project’s root directory. Add the following assemblies in the assemblies tag that is placed under the compilation tag.

web.config

<compilation debug="true" targetframework="4.5.1">
    <assemblies>
          <add assembly="Syncfusion.EJ, Version=14.2451.0.26, Culture=neutral, PublicKeyToken=3d67ed1f87d44c89" />
          <add assembly="Syncfusion.EJ.Mvc, Version=14.2500.0.26, Culture=neutral, PublicKeyToken=3d67ed1f87d44c89" />
    </assemblies>
</compilation>
The highlighted version denotes the version based on .NET framework that is used in the application. Replace the xxxx versions in your sample according to the installed assembly versions.
