FluentAssertions.Analyzers.dll' References Version '4.11.0.0' of the Compiler Warning: A Solution to the Issue

When working with .NET projects, it's not uncommon to encounter compiler warnings that can be frustrating to resolve. One such warning is the "FluentAssertions.Analyzers.dll' references version '4.11.0.0' of the compiler" error. This warning typically occurs when the project is targeting an older framework version, such as .NET Framework 4.7.2, and the FluentAssertions.Analyzers package is referencing a newer version of the compiler. In this article, we'll explore the cause of this warning and provide a solution to fix it.

The error message indicates that the FluentAssertions.Analyzers.dll file is referencing version 4.11.0.0 of the compiler, which is newer than the currently running version 4.10.0.0. This warning is triggered because the project is targeting .NET Framework 4.7.2, which corresponds to the 4.10.0.0 compiler version. The FluentAssertions.Analyzers package, on the other hand, is referencing the newer 4.11.0.0 compiler version.

Why is this a Problem?

The issue here is that the project is not compatible with the newer compiler version referenced by the FluentAssertions.Analyzers package. This can lead to compilation errors or unexpected behavior when running the application.

Is the Version We're Using Supported?

The version of FluentAssertions.Analyzers we're using (0.34.2) is still a supported one, as shown in the screenshot below:
