netcore support

Steps to reproduce

1. create a dotnet project dotnet new console -n test
2. enter the project cd test
3. add nuget package dotnet add package DotSpatial.Projections --version 2.0.0-rc1
4. exec build dotnet build

DotSpatial version: 2c2302778278e61a01143b1ea6c8126a3ae8198e

Expected behaviour

compatibility on net standard

Actual behaviour

warn : Package 'DotSpatial.Projections 2.0.0-rc1' was restored using '.NETFramework,Version=v4.6.1' instead of the project target framework '.NETCoreApp,Version=v2.1'. This package may not be fully compatible with your project.

Feature description

Currently I copied DotSpatial.Projections sources to another repository to adapt for use with dotnet. I wondering if DotSpatial.Projections could enabled to generate only a Net Standard dll so that it can be used even from NET Framework referencing assemblies directly using packages from DotSpatial instead to build my own.

You can try NET standard version by adding following packages to a net framework project

Install-Package netcore-proj -Version 1.0.0-CI00004 -Source https://www.myget.org/F/devel0/api/v3/index.json

Follows major changes to the DotSpatial.Projections:

• removed Properties folder
• changed csproj to generate netstandard and embed resource datums.xml.ds. Note that I used different name to avoid upgrade hint on myget same package name that already exists.
• handle resource name respect framework mangling used

I know, but the problem for me is that there are some package deployment actions that I can’t verify, would be better if someone that have hands on this project nuget packages makes a working copy transition test with:

• transform DotSpatial.Projections to net standard
  • csproj

<Project Sdk="Microsoft.NET.Sdk">
    <PropertyGroup>
        <TargetFramework>netstandard2.0</TargetFramework>
        <GenerateDocumentationFile>true</GenerateDocumentationFile>
    </PropertyGroup>
    <ItemGroup>
        <EmbeddedResource Include="XML/datums.xml.ds" />
    </ItemGroup>
</Project>

• • remove Properties folder
  • change embedded assembly string referencing depending on the framework

var resourceName = "netcore-proj.XML.datums.xml.ds";
if (!RuntimeInformation.FrameworkDescription.StartsWith(".NET Framework"))
  resourceName = "netcore-proj.datums.xml.ds";

• doublecheck everything works with existing unit tests
