Needs Info
Unable to build this, Inventory.Data & Inventory.ViewModels build success but unable to build inventory.App
What kind of error are you getting?
All nuget | references r restored in Inventory.Data & Inventory.ViewModels expect Inventoy.App i'm using release version 1.2.4

It seems to be a problem restoring nuget packages.
Please, refer to the following documentation for package restore troubleshooting:
https://docs.microsoft.com/en-us/nuget/consume-packages/package-restore-troubleshooting
You can also try to remove the current project and try downloading a fresh copy with the latest version.
Please, let me know if this helps.
I have checked, but my issue is't resolved. i have cloned proj, also downloaded Latest release. same issue
@sajjadjaved01 can you install any package from NuGet? I'm wondering if you can add any package to a blank new app.
Did you try cleaning the nuget cache? https://docs.microsoft.com/en-us/nuget/consume-packages/managing-the-global-packages-and-cache-folders

Thanks for your response.
I have clear nuget cache
then i've looked at temp dir C:\Users\sajja\AppData\Local\NuGet\v3-cache\
there the nuget packg r dwnloading, after completion VS dos't show anything compete / success etc. but it stays on building.
after some time i have canceled build & then again Rebuild proj, nuget again started dwnloading, already dwnloaded packg in temp dir.
