In my publish profile the Target Framework was set to NET5.0. Changed it to NET6.0 and the problem was gone.

Update to Nuget 5.8 Clear the local cache

error NETSDK1005: Assets file 'project.assets.json' ....

Try updating NuGet.exe to the 5.8.0 version or above:

nuget update -self

if you prefer to update the nuget version in Visual Studio, just follow this steps. Then, clear NuGet cache:

dotnet nuget locals all --clear

Download Nuget

Delete the 'obj' folder and re-build the project.

You're using an extremely old .NET 5 preview. ASP.NET Core Preview 1 specifically had no new features, it was essentially a version number change. There's no netcoreapp5.0 framework target any more, it's net5.0.

The latest version is 5.0 RC1 which is feature-complete and supported in production. Install it and create a new project with, eg dotnet new webapp or dotnet new webapi etc.

This version is supported by the latest Visual Studio 2019 Preview version.
