WPF - Using Windows Media Import-CodePudding

I am trying to use the Windows Media Import API in a WPF Application I have added a reference to the Windows Runtime but still failing to get it to run. Any ideas what the missing references may be?

CodePudding user response：

Your .csproj is targeting an ancient and unsupported version of .NET Framework, specifically: .NET Framework 4.0 which dates back to 2010, which is before the IReadOnly...<T> collection interface types were added to .NET in .NET Framework 4.5 in 2012.

As it's 2021, you should now be targeting either .NET Framework 4.8 - or .NET 5. As porting to .NET 5 is a large undertaking, just update to .NET 4.8:

So change this:

<TargetFrameworkVersion>v4.0</TargetFrameworkVersion>

to this:

<TargetFrameworkVersion>v4.8</TargetFrameworkVersion>
