Hi.After installing the package Nuget "Syncfusion.EJ2.Blazor" an error has occurred:
InvalidOperationException: Cannot provide a value for property 'SyncfusionService' on type 'Syncfusion.EJ2.Blazor.Grids.EjsGrid`1[[PTS.Models.Movie, PTS, Version=, Culture=neutral, PublicKeyToken=null]]'. There is no registered service of type 'Syncfusion.EJ2.Blazor.SyncfusionBlazorService'.

I use Custom DataAdaptor:

    // Implementing custom adaptor by extending the DataAdaptor class
    public class MovieAdaptor : DataAdaptor
        readonly ApplicationDbContext db;
        private readonly IMapper mapper;

Hi Costa,

For the latest version, we need to add syncfusion blazor as a service in our startup.cs

Add the following using statement near the top of startup.cs

using Syncfusion.EJ2.Blazor;

Then in the ConfigureServices method add the following


Please can a Syncfusion dev confirm this -- I have done it and got it working, but still would be nice to have an official word.
Also, please can Syncfusion update the Getting Started documentation for Blazor to include this information.

Thank you, Matthew. The solution works.

Hi Matthew / Costa, 

Thanks for contacting Syncfusion support.  

Query: “Please can a Syncfusion dev confirm this -- I have done it and got it working, but still would be nice to have an official word. 
Yes, from our latest release 2019 Volume 4 (, we need to include the below highlighted line to ignore the Syncfusion service reference error while using the Syncfusion Products. 

Refer the below code example.   


  public void ConfigureServices(IServiceCollection services) 

Refer our UG documentation for your reference 

Please get back to us if you have further queries.  

Vignesh Natarajan.
