Building the solution and creating the NuGet package

Packaging project

The UiPath.Activities.Template includes a packaging project that creates a NuGet package every time the solution is built. Alternatively, you can manually create a package using NuGet Package Explorer.

It is important to configure the packaging project to ensure the correct metadata is added to the package. To do this, open the packaging CSPROJ file and configure the properties described in the following table.

Property	Description
GeneratePackageOnBuild	Whether to generate a package when building the solution
VersionBuild	Build number
VersionRevision	Revision number
PackageId	Name of the package
VersionPrefix Condition="'$(Configuration)' == 'Release'"	Version prefix for a stable release
VersionPrefix Condition="'$(Configuration)' == 'Debug'"	Version prefix for a debug release
Authors	Author of the package, for example your team or organization. Do not add UiPath as the package author.
PackageTags	Tags to display for the package
Description	Package description
PackageIconUrl	URL of the icon to add to the package
PackageOutputPath	Folder where to create the package
TargetsForTfmSpecificBuildOutput	What to include in the build output

The properties for the sample Calculator activity look as follows:

<PropertyGroup>
		<GeneratePackageOnBuild>True</GeneratePackageOnBuild>
		<VersionBuild>$([System.DateTime]::UtcNow.DayOfYear.ToString("F0"))</VersionBuild>
		<VersionRevision>$([System.DateTime]::UtcNow.TimeOfDay.TotalMinutes.ToString("F0"))</VersionRevision>
		<PackageId>UiPath.MyCustom.Activities</PackageId>
		<VersionPrefix Condition="'$(Configuration)' == 'Release'">1.0.0</VersionPrefix>
		<VersionPrefix Condition="'$(Configuration)' == 'Debug'">1.0.$(VersionBuild)-dev.$(VersionRevision)</VersionPrefix>
		<Authors>MyCompany</Authors>
		<PackageTags>UiPathActivities</PackageTags>
		<Product>UiPath.MyCustom.Activities</Product>
		<PackageIconUrl>https://download.uipath.com/UI_icon.png?web</PackageIconUrl>
		<PackageOutputPath>..\Output\Activities\Packages\</PackageOutputPath>
		<TargetsForTfmSpecificBuildOutput>AddDlls</TargetsForTfmSpecificBuildOutput>
		<ProduceReferenceAssembly>False</ProduceReferenceAssembly>
	</PropertyGroup>

Building the project

Make sure you test the project for errors before attempting to build it. To build the solution, select Build Solution from the Build menu.

• The default location where solutions are saved is %UserProfile%\source\repos.
• The default location where NuGet packages are saved is %UserProfile%\source\repos\<Solution_Folder>\<Solution>\Output\Activities\Packages.
