DNTCommon.Web.Core provides common scenarios' solutions for ASP.NET Core applications.
To install DNTCommon.Web.Core, run the following command in the Package Manager Console:
PM> Install-Package DNTCommon.Web.CoreYou can also view the package page on NuGet.
The SkiaSharp library needs extra dependencies to work on Linux and containers. Please install the following NuGet
packages:
PM> Install-Package SkiaSharp.NativeAssets.Linux.NoDependencies
PM> Install-Package HarfBuzzSharp.NativeAssets.Linux
You also need to modify your .csproj file to include some MSBuild directives that ensure the required files are in a
good place. These extra steps are normally not required but seems to be some issues on how .NET loads them.
