Code Generation error while creating Api Controller in VS 2019

I am trying to create a Web API controller, but it somehow always throws the following error:

There was an error running the selected code generator: The value -1 is outside the acceptable range of [02147483647]. Parameter name Value

I have removed the extra NuGet packages I added, like Cors, Owin, etc but it is still throwing that error

I too got the same error while auto generating API controller code.

Since I was just messing around with a practice project, I just took the liberty to upgraded my project to the latest ASP.NET Core version along with the NuGet packages required by the code generating tool

  • Microsoft.EntityFrameworkCore
  • Microsoft.EntityFrameworkCore.SqlServer
  • Microsoft.EntityFrameworkCore.Tools

After the updates The Code generation tool worked properly.

Try creating the Web Api via 'Web API Controller Class (v2.1).. this works for me..

Looks like an update problem with VS2019
