Hi @Vivek.Mapara Eikon users can also access services on our Refinitiv Data platform using the Refinitiv Data Platform libraries (which have a .NET version in alpha release) and an EIkon app key by opening a desktop session. These services include streaming prices, historical prices (timeseries history), all TR fields are also now available via the datagrid endpoint, search and many other services which are coming on to the platform. You can find more details here. From this document you can see the supported configuration for the .NET version:

All examples are built with Microsoft .Net Framework 4.5.2 and should be pre-installed. The library supports .NET Framework 4.5.2, and .NET Standard 2.0, 2.1. With the .NET Standard support, applications can be targeted to use up to .NET Core 3.1.

All examples will automatically download NuGet dependencies when loading/building a solution. NuGet Package Manager 2.12 (or greater) is required to be pre-installed prior to loading the solution. The minimum Package Manager is available within the modern Visual Studio IDE's such as 2017, 2019. Developers may need to upgrade their package managers for older IDE's such as VS2015.

You can get the current package from NuGet and the samples are available here. A quick start guide is available here for .NET

So right now it really depends on what data you require - some of it is available right now and shortly much more will be there natively in .NET. I hope this can help.
