get error Assets file 'obj\project.assets.json' doesn't have a target for '.NETCoreApp,Version=v2.2'

I upgrade my MVC Core Project from 2.2 to 3.0 with microsoft

and change many recommended here: https://stackoverflow.com/

It works fine when run it in Local, but when I want publish in local folder I get this error :

Assets file 'obj\project.assets.json' doesn't have a target for '.NETCoreApp,Version=v2.2'. Ensure that restore has run and that you have included 'netcoreapp2.2' in the TargetFrameworks for your project

Ii have 3 projects and all of them upgrade to MVC core 3.0 also upgrade all packages to 3.0 also remove object folder and bin folder and build projects again, close VS and open it again but the error stil exists.

UPDATE: mvc project csproj

<Project Sdk="Microsoft.NET.Sdk.Web">

<PropertyGroup>
  <TargetFramework>netcoreapp3.0</TargetFramework>   
</PropertyGroup>

<ItemGroup>
 <!--<PackageReference Include="Microsoft.AspNetCore.App" />-->
  <PackageReference Include="Microsoft.AspNetCore.Identity.UI" Version="3.0" 
 />      
   <PackageReference Include="Microsoft.VisualStudio.Web.CodeGeneration.Design" 
Version="3.0.0" />
</ItemGroup>

<ItemGroup>
  <Folder Include="Areas\Admin\Data\" />
  <Folder Include="Areas\Admin\Models\" />
 </ItemGroup>

<ItemGroup>
  <ProjectReference Include="..\project.Model\project.Model.csproj" />
  <ProjectReference Include="..\project.Repo\project.Repo.csproj" />
</ItemGroup>

</Project>

My project.Model.csproj

<Project Sdk="Microsoft.NET.Sdk">

<PropertyGroup>
  <TargetFramework>netcoreapp3.0</TargetFramework>  
</PropertyGroup>

<ItemGroup>
  <PackageReference

If you run publish with the command line (dotnet publish), make sure you specified the correct framework with option "-f".

If you are doing this in a lambda then make sure to update aws-lambda-tools-defaults.json and serverless.template files.

In our case we had a very similar error when Publishing, after switching from netcoreapp30 to netcoreapp31 as the target Framework. We solved it by:

  1. Closing Visual Studio
  2. Deleting the file \obj\project.assets.json
  3. Opening the solution again
  4. Rebuild Solution

After that we were able to Publish the project fine.

This happens usually when you upgrade the .net core version. The solution is to create new publish profile. Not edit, simple create new publish profile and target the new .net core version that you have upgraded.

Make sure your Publish Profile says netcoreapp3.0 for the TargetFramework.
