I have upgraded my projects from .Net Core 2.2 to .Net Core 3.1. Currently everything is working fine except below error -

Severity Code Description Project File Line Suppression State Error CS1061 'Type' does not contain a definition for 'ShortDisplayName' and no accessible extension method 'ShortDisplayName' accepting a first argument of type 'Type' could be found (are you missing a using directive or an assembly reference?)

Code is as below :

ex.GetType().ShortDisplayName()

I believe there should be some substitute available for ShortDisplayName in 3.1 but don't know how to get it.

Kindly help.

First add package to your project. It's package name described here

dotnet add package Microsoft.EntityFrameworkCore -v 3.1.0

Then, You should add Microsoft.EntityFrameworkCore.Infrastructure as using statement.

CodePudding user response：

Type class has never had a method with this name and if it had, its name would start with Get and be GetShortDisplayName().

The lack of Get strongly suggests that this is a custom extension method that you didn't yet port to your new project.
