Ensure seamless deployment with these essential components. The Apryse The following page describes some of the SDK prerequisites. ## C/C++ **Native C/C++ library** The Apryse native C/C++ library is fully self contained and does not have any dependencies. The native libraries are statically linked with the runtime library used by it, therefore allowing it to be used/deployed without any dependencies. ## .NET ### **Dependencies for .NET** The PDFNet .NET libraries for .NET Standard, .NET Core and .NET 5+ are self-contained and have no external dependencies. ### **.NET Framework 4.5.1+** End users of applications developed with Apryse SDK for .NET 4.5.1+ will need the Microsoft Visual C++ v14 redistributable on their system. This is a standard component of Visual Studio, which is why it was not needed during development. End users, or server Admins, may be instructed to install these files directly using the package from Microsoft, or the DLLs can be included as part of the application install by including it in the same folder as your application. The appropriate (x86/x64) version of the VC++ v14 runtime needs to be installed, based on the platform architecture that you are targeting. What about AnyCPU? Isn't this .NET we are talking about? Of course AnyCPU is supported - please see the [deployment](/core/learn-more/platform-specifics/deployment.md) section for all the details. The above components are available for download directly from the Microsoft website. The download links are given below. ## Downloads: * [VC++ v14 Redistributable](https://learn.microsoft.com/en-us/cpp/windows/latest-supported-vc-redist?view=msvc-170) --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.apryse.com/core/learn-more/platform-specifics/prerequisites.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
