Hi, I'm getting too many warnings when running dotnet build, Please help me in solving these warnings. My projects were targeting to .net standard 1.0, now I am targeting to .net standard 2.0 with the same code.

Why I cannot see target framework.core 2.0 in the target framework?

I have downloaded code from aspnetzero site which was targeting 1.1.

I downloaded .net standard 2 sdk from Microsoft site. I’m trying to set target framework of projects to core2.0. But I cannot see this option. I’m seeing all .standdard in target framework drop down .

Then I downloaded the code from aspnetzero site for core2.0. In this project I can see target framework core 2.0.

So what’s difference between .core 2.0 and .net standards 2.0?

How it will impact my code which is using the abp framework.

What’s difference between .core 2.0 and . net standards 2.0?

I cannot see .core 2.0 option in the target framework drop down in project properties. I can see only .net standards 1.1......... .net standards 2.0.

How will it impact by project which is based on abp framework?

Then I downloaded the project from aspnetzero site for core 2.0. In it’s project I can see .core 1.1 and core2.0 not .net standards, why?

Hi @ManojReddy,

If you want to change target framework of your project, just right click on your project and select "Edit ****.csproj". Then you can change TargetFramework.

ABP supports both, .Net Standard 2.0 & .Net Core 2.0.

But why it's not showing .net core 2.0 in the target framework dropdown list when you right-click the project and select properties.

Whats difference between .net standard and .net core?

What do you suggest? Should I target .net standard or .net core?

I'm not sure why VS does not show .Net Core when changing Target Framework. You can change it directly by editing *.csproj files.

It is better if you can read this document in order to understand purposes of all those, <a class="postlink" href="https://msdn.microsoft.com/en-us/magazine/mt842506.aspx">https://msdn.microsoft.com/en-us/magazine/mt842506.aspx</a>.
