Assemblies

The Subsembly SEPA API consists of several core assemblies compiled for .NET Standard 2.0. See https://docs.microsoft.com/de-de/dotnet/standard/net-standard for a table of .NET Standard 2.0 compatible platforms.

The following core assemblies were compiled for .NET Standard 2.0 and can be added to any project that targets a .NET Standard 2.0 compatible environment:

  • Subsembly.Crypto.dll
  • Subsembly.Csv.dll
  • Subsembly.Json.dll
  • Subsembly.Sepa.dll

Also, you must add a NuGet reference to System.Text.Encoding.CodePages by Microsoft (see https://www.nuget.org/packages/System.Text.Encoding.CodePages/4.7.1), or add the following files to your installation:

  • System.Runtime.CompilerServices.Unsafe.dll
  • System.Text.Encoding.CodePages.dll

In addition the following files should be added to your development environment in order to support the Visual Studio Intellisense:

  • Subsembly.Json.xml
  • Subsembly.Sepa.xml

All of these assemblies and files are contained in the Subsembly SEPA API software development kit.
