Hi @Mustafa ,
The error message means that Microsoft.EntityFrameworkCore.SqlServer.Query.Internal.SqlServerSqlTranslatingExpressionVisitorFactory type has a mention of Create method in your code/library, but it is unable to find it as there is a wrong version's reference of the nuget package in which Create method is not present.
Please note that all the following packages should be of same version:
From the image, all of these should be 3.1.15.0 version.
If still not working, you could check out this solution.
Besides, you could also tell us your application version, Visual Studio version, post the .csproj file content and post the related code to reproduce the problem.

Install-Package Microsoft.EntityFrameworkCore.Tools -Version 5.0.7
