Using CI builds

To use CI builds add the following nuget feed:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
    <packageSources>
        <clear />
        <add key="XLW" value="https://f.feedz.io/xlw/xlw/nuget/index.json" />
        <add key="NuGet.org" value="https://api.nuget.org/v3/index.json" />
    </packageSources>
</configuration>

XLW

xlw is being updated.

This repo was originally forked from John's XLW repo which itself was imported from it's original home at SourceForge

This version will only support Visual Studio 2019 for now. Support for all previous Visual Studio versions has been dropped. All support for gcc has also been dropped.

Support is being added for building xlls against .NET CORE & .NET Framework 4.7.2

An initial dev nuget package for building C/C++ xlls is avaialable at xlw@nuget.
And a nuget package for building C# xlls is available at xlwDotNet@nuget.

xlw for building C++/C xlls has not changed much at this point. To build a C++ xll :

1. Create an empty C++ DLL project.
2. Add the xlw nuget package.

Only VS2019 is supported right now. To build a C# xll :

1. Create a new .NET Core library project.
2. Open the .csproj file with a text editor and set the TargetFramework and Platform for example

<Project Sdk="Microsoft.NET.Sdk">
  <PropertyGroup>
    <TargetFrameworks>net5.0</TargetFrameworks>
    <Platforms>x64</Platforms>
  </PropertyGroup>
</Project>

3. Add the xlwDotNet nuget package.
