Unable to compile 3.2 and earlier projects after upgading to 3.3 SDK

[StuartBricker2]

I upgraded both ArcGIS Pro and the Visual Studio SDK extensions to version 3.3 this morning.

Subsequently, I receive compilation errors when attempting to build existing projects as per the attached screen capture. As a workaround, I was able to create a new 3.3 project and copy/paste the code into the new project for the script I needed to run at the time. That compiled and ran just fine. 

However we have some larger apps where that workaround is not really viable and I'd like to resolve the issue that is preventing these existing projects from compiling. Clearly something went sideways with the upgrade and I am getting version mismatch errors.

Thanks in advance for any assistance you are able to provide.

ArcGIS Pro moved to .NET 8 at release 3.3. so update the target framework to .NET 8 and VS 2022 (17.8 or higher).

Place to start is to ensure your Visual Studio 2022 is at version 17.8 or higher and that you have .Net 8 installed.

Thanks for the replies. I knew it had to be something silly that I was missing. Again.
