Version 1.11.1 and higher cannot be used on .Net Framework

[iant-ee]

When I try and install 1.11.1 or 1.12.0 in a .Net Framework project using NuGet I get the error message:

Could not install package 'FirstData.Gateway 1.11.1'. You are trying to install this package into a project that targets '.NETFramework,Version=v4.7.2', but the package does not contain any assembly references or content files that are compatible with that framework. For more information, contact the package author.

It appears that you've bumped your .NET Standard version from 2.0 to 2.1. This is a major breaking change - was it intentional or required? How should .NET Framework users continue to integrate with Fiserv?

Note:

• .NET Standard 2.0 supports .NET Core and .NET Framework.
• .NET Standard 2.1 only supports .NET Core

For the next release we will revert to .Net Standard 2.0. There is demand for a package targeting 2.1, but as you pointed out, we can't introduce a breaking change like this. Target is first week of September for the next release.

Thanks for bringing this to our attentiton.
