Could not load type 'Microsoft.EntityFrameworkCore.RelationalReferenceReferenceBuilderExtensions' from assembly 'Microsoft.EntityFrameworkCore.Relational, Version=3.0.0.0

When querying for relational data, in localhost is working as expected.

Steps to reproduce

Update to Net core 3.0 and EF Core 3.0 and deploy to IIS with Self-Contained and Framework dependent both deploy type is not working

Further technical details

EF Core version: 3.0
Database provider: Microsoft.EntityFrameworkCore.SqlServer
Target framework: .NET Core 3.0
Operating system: Windows Server 2016 Data Center + Net Core runtime
IDE: Visual Studio 2019 16.3

<?xml version="1.0" encoding="utf-8"?> <configuration> <location path="." inheritInChildApplications="false"> <system.webServer> <handlers> <add name="aspNetCore" path="*" verb="*" modules="AspNetCoreModuleV2" resourceType="Unspecified" /> </handlers> <aspNetCore processPath=".\<app>.exe" stdoutLogEnabled="false" stdoutLogFile=".\logs\stdout" /> </system.webServer> </location> </configuration>

I managed to solve the issue by changing the web.config by using default from deployment
