.net-framework-version

问题 I have a scenario where we are using a legacy .Net Framework dll in .Net core 3.1 class library. Internally .Net Framework dll is using System.Windows.Forms.dll which .Net core is not able to resolve. I am getting below error message during runtime Could not load file or assembly 'System.Windows.Forms, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'.

问题 I am trying to start WAS service and I got this error from Event Viewer. Windows Process Activation Service (WAS) is stopping because it encountered an error.

问题 We have a C# project where the C# projects are compiled with TargetFrameworkVersion 4.7.2. For example, in the csproj file this is specified -- <TargetFrameworkVersion>v4.7.2</TargetFrameworkVersion> The compiled and built exe is installed in a VM which has .net 4.6.1 installed. I see that installation is successful and the software is working fine. So can we safely say that projects built with 4.7.2 can execute when .netframework 4.6.1 installed. Or are there any issues to look out for here
