Visual Studio 2019 SyncFusion Blazor Project

[David]

After installing the SF tools for VS and Blazor, I create a new project using the SyncFusion Blazor template.

Without me touching any code, the project won't build.

I get the following errors:

CS0234 The type or namespace name 'Blazor' does not exist in the namespace 'Syncfusion.EJ2' (are you missing an assembly reference?)

This error is in the _Imports.razor file as well as the Startup.cs file of the CLIENT project that is created when using SyncFusion's template.

Hi David,  

 

Thanks for contacting Syncfusion support.  

 

Syncfusion Blazor NuGet packages name, control names and namespace has been changed from the 2020 Volume 1 beta release (18.1.0.36-beta). The Syncfusion Blazor Project Templates creating the Blazor application with the latest version of NuGet packages which is available in the nuget.org. In nuget.org we have published the old and new Syncfusion Blazor NuGet packages with the version 18.1.0.36-beta. So, in your case  you are installing the 17.4.0.46 version blazor setup, but Syncfusion NuGet packages are referred with the version 18.1.0.36-beta as per the behavior of the Syncfusion Blazor Project Template. Please see the below release notes link for the naming changes.
