NuGet Error NU5036

This package has an improperly escaped Url in LicenseUrl

Issue

LicenseUrl metadata value in the nuspec file should be properly escaped. Some versions of nuget pack functionality have a problem which will be updated asap.

Solution

Use a fixed version of nuget pack functionality:

• "NuGet.exe pack" - fixed in 4.9.1
• "dotnet.exe pack" - broken in 2.1.500. No fix available yet. (don't use new License expression or file feature yet, to avoid problem.)
• "msbuild /t:pack" - broken in Visual Studio 15.9.1. No fix available yet. (don't use new License expression or file feature yet, to avoid problem.)
