I couldn't figure out the best area label to add to this issue. If you have write-permissions please help me learn by adding exactly one area label.

This "work around" did the trick. I realize as programmers we deal with cryptic errors everyday, but at this point VS2022 should have the smarts to actually tell the user what a solution might be, or at a minimum... a more incisive error description. Shouldn't conflicting SDK checks be inherent at this stage in the development cycle? Maybe the "Repair" feature could analyze these potential issues? My project uses .NET 6 and not .NET 7, but this still prevented the project from loading.

[MickCG]

OK, I noticed that there is a work around which I do not see on this page, what am I missing? I swear I have had a weekend of trying to get to the bottom of this finally did a remove and a cleanup. Reinstalled VS 2022 latest tried to get back to close to bear bones, no good. Funny thing is I have a Azure VM with windows 11 I use at work some and other than it does have a preview version of framework 7, virtually the same and it works after installing 17.4.0?????

[GuildOfCalamity]

@MickCG The problem was introduced at version 17.5.0 (17.4.0 works fine) Uninstall any instance of .NET 7 Preview SDK and 17.5.0 should work for you.

Please see this known issue: https://github.com/dotnet/core/blob/main/release-notes/7.0/known-issues.md#70-projects-using-certain-workloads-dont-load-build-and-or-run-if-net-7-preview-sdk-workloads-are-installed

The problem is compatibility with any 7.0 SDK from preview 7 or older. Removing the older SDK should solve the issue.
