    Hello @iqworks Information Quality Works ,

    Sometimes, the project cache may cause this issue(something in one of the cache files maybe still reference to an old version of .NET Framework).

    Please try to remove bin, obj and the hidden .vs folder manually, and then rebuild your project, do a NuGet restore.

    What type of project is this? Go to the file system where the project resides, is it a .csproj file?

    Open the file in a text editor. Is it XML and does it start with something like

    <?xml version="1.0" encoding="utf-8"?>
    <Project ToolsVersion="15.0" DefaultTargets="Build" xmlns="">

    If it doesn't then the project file isn't correct. If it does then find the <TargetFrameworks> element. It should have a value of v4.7.2.

    If the file instead looks like this.

    <Project Sdk="Microsoft.NET.Sdk.Web">

    Then you're using a new SDK-format project for .NET framework. This isn't going to work out well so create a new ASP.NET project targeting NET Framework. If this is not a web-project then you can use the SDK format but ensure you have the following element inside a PropertyGroup.


    I'm assuming here you're actually loading the solution/web project. If you aren't then nothing is going to work.
