                                  • I am receiving the attached(and below) error. There is a ticket numbered T830016 that I can not view with the same error and I cannot find any other information on it. I am not sure where I should start looking for the cause of the error. The program worked on Friday, so I tried reinstalling devexpress packages and had no luck. Any idea what could cause this error?
                                    Thanks

                                Hello,

                                This issue relates to the fact that you use the .NET Core 3.1 preview template. In this case the corresponding service is not included automatically. We are working on this issue and it should be resolved in the next release of our components.
                                Right now, I recommend you include our service manually. Open the "Startup.cs" file and include our namespace:

                                [C#]
                                using DevExpress.Blazor;

                                Then, call the AddDevExpressBlazor method in the ConfigureServices function:

                                [C#]
                                public void ConfigureServices(IServiceCollection services) { //... services.AddDevExpressBlazor(); }

                                Please try this approach and let me know if it helps.

                                Regards,
                                Vova
