 .NET for Apache Spark is compliant with .NET Standard - a formal specification of .NET APIs that are common across .NET implementations. This means you can use .NET for Apache Spark anywhere you write .NET code allowing you to reuse all the knowledge, skills, code, and libraries you already have as a .NET developer. 
 
-.NET for Apache Spark runs on Windows, Linux, and macOS using .NET Core, or Windows using .NET Framework. It also runs on all major cloud providers including [Azure HDInsight Spark](deployment/README.md#azure-hdinsight-spark), [Amazon EMR Spark](deployment/README.md#amazon-emr-spark), [AWS](deployment/README.md#databricks) & [Azure](deployment/README.md#databricks) Databricks.

 **Note**: We currently have a Spark Project Improvement Proposal JIRA at [SPIP: .NET bindings for Apache Spark](https://issues.apache.org/jira/browse/SPARK-27006) to work with the community towards getting .NET support by default into Apache Spark. We highly encourage you to participate in the discussion.

 ## Good to know while implementing UDFs
 
-One behavior to be aware of while implementing UDFs in .NET for Apache Spark is how the target of the UDF gets serialized. .NET for Apache Spark uses .NET Core, which does not support serializing delegates, so it is instead done by using reflection to serialize the target where the delegate is defined. When multiple delegates are defined in a common scope, they have a shared closure that becomes the target of reflection for serialization. Let's take an example to illustrate what that means.
