  Cognitive search and Elastic search Azure Cognitive Search :-  The Azure Cognitive Search service enables search over different types of content by letting you create and manage search indexes. You can import data from a variety of sources, with AI-powered indexing that can infer and extract searchable content from non-text sources. You decide what data is imported into the index, and set up indexers to pull that data into it, or push JSON formatted documents manually. Azure Cognitive Search also lets you query search indexes. The results contain only your data, which can include text inferred or extracted from images, or new entities and key phrases detection through text analytics.

TLS 1.0 is a security protocol first defined in 1999 for establishing encryption channels over computer networks.  Microsoft has supported this protocol since Windows XP/Server 2003.  While no longer the default security protocol in use by modern OSes, TLS 1.0 is still supported for backwards compatibility.  Evolving regulatory requirements as well as new security vulnerabilities in TLS 1.0 provide corporations with the incentive to disable TLS 1.0 entirely.  TLS 1.2 is a standard that provides security improvements over previous versions. TLS 1.2 will eventually be replaced by the newest released standard TLS 1.3 which is faster and has improved security.   To ensure .NET Framework applications remain secure, the TLS version should  not  be hardcoded. .NET Framework applications should use the TLS version the operating system (OS) supports. With TLS 1.2/1.3 change impact the source code uses the following namespace/library/classes. Directly using the...
