Adding Refit Version 6.3.2 to MVC Application causes Error and Renders Application Unusable

[QueenBee61]

When I try to add Refit Version 6.3.2 I receive the following error on build:

Packages.config does not support Analyzers, including Source Generators. Migrate to PackageReference: 'https://devblogs.microsoft.com/nuget/migrate-packages-config-to-package-reference/'

It is not usable in MVC Applications? Is there a particular version I must use? I am able to install version 4.0, in the MVC application but then I can't use the SDK created with 6.3.2. I tried to create the SDK using 4.0 and receive the error "ApiResponse" does not exist.

Isn't this telling you what to do?

It doesn't work. It tells me either the project is not using packages.config or is not eligible, or something on that order.

@QueenBee61 there are ways to force VisualStudio to think its eligible. You need to edit the .csproj file and change it to a class library then you can migrate it. I just did it. It was lots of work with a big repo, but doable. This StackOverflow article helped me https://stackoverflow.com/questions/57581514/vs-2015-to-2017-migrate-to-package-reference-failed

@jakeshoemaker - thanks!

What version of Refit do I need to downgrade to that will support packages.config? I can't afford to migrate a huge MVC project on full framework today.
