Hi Hasan Kosten,


Thanks for contacting Syncfusion support.

As per the screenshot of the issue you have shared we suspect that the issue occurred since Visual Studio 2019 have some problems in your machine. Could you please reset the Visual Studio 2019 by follow the below steps and try to create the Syncfusion ASP.NET Core application.

  1. open the below location in command prompt.
    C:\Program Files (x86)\Microsoft Visual Studio\2019\Professional\Common7\IDE
       2. Then run the below command.
           devenv /ResetSettings 


If Syncfusion ASP.NET Core Project template extension has been uninstalled after reset the Visual Studio 2019, please install it manually by follow the steps from the below blog.
