"Error: Could not install package" when Installing iCal.NET from "Manage NuGet Packages" Feature in Visual Studio

Question

I would like to install iCal.NET from "Manage NuGet Packages" feature in Visual Studio 2013. However, I got an error:

Error: Could not install package 'System.Reflection.TypeExtensions 4.1.0'. You are trying to install this package into a project that targets '.NETFramework,Version=v4.5', but the package does not contain any assembly references or content files that are compatible with that framework. For more information, contact the package author

My project itself uses .NET Framework 4.5:

But if I download iCal.NET directly from here, I can set it as reference with no error.

Anyone knows with this issue?

EDIT

I just found this discussion: https://github.com/rianjs/ical.net/issues/101

It seems iCal.NET should be able to support .NET 4.5 since Nuget package version 2.2.7

Answer 1

v4 of ical.net supports net46 and higher, which would be .NET Framework 4.6. One of my dependencies, System.Reflection.TypeExtensions, doesn't support framework versions below 4.6, so I can't go lower than that.

You're welcome to continue using v2, which will work, but isn't updated any longer. If this is an application you have full control over, I would suggest targeting .NET 4.6.latest, if you can.

As a general note, the nuget page for any library will tell you what versions of things they depend on if you click the Dependencies header. While I was looking at the ical.net gallery page, I noticed that my dependencies weren't as clear as they could be, so I published a new version (4.1.7) that makes it clearer what they are.
