I've just create ASP.NET Core Web Application, and then when I run, I it's show message errors!

You can use .net core 3.1. Any specific use case to use .net 5 perview? or is it just for learning purpose? — Rajdeep Debnath
@RajdeepDebnath it's not a Preview, it's a fully supported RC with a Go Live license. There are no build problems — Panagiotis Kanavos
He is using preview as mentioned in the error C:\Program Files\dotnet\sdk\5.0.100-preview.1.20155.7\Sdks\Microsoft.NET.Sd — Rajdeep Debnath
netcoreapp5.0 there's no such target. It's net5.0. Did you edit the csproj manually perhaps? Or use an outdated SDK? Install the latest .NET 5 SDK and just create a new project, eg dotnet new web or dotnet new webapp — Panagiotis Kanavos

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
