Describe the bug
I have seen an article with the same subject but I am not been able to resolve my problem using that solution...

I am following an article of running Apache Spark with asp.net C#.
when I ran the command from cmd I got error as described in the subject.

Expected behavior
System must produce the simple output as described in the blog.

Screenshots

Desktop (please complete the following information):

• OS: Windows 10 64 bit
• Browser Chrome
• Version 81.0.4044.129 (Official Build) (64-bit)

Additional context
I am using Apache Spark 2.4.5 with the environment variable as below spark_home=C:\spark_home\spark-2.4.5-bin-hadoop2.7
dotnet_worker_dir=C:\spark_home\Microsoft.Spark.Worker-0.10.0
hadoop_home=C:\WinUtils

rest of the path in spark_submit command is valid and accessible...I ran the spark_submit from the bin/debug/netcoreapp3.1 folder as described in the blog.

I have changed the line from --class org.apache.spark.deploy.DotnetRunner to --class org.apache.spark.deploy.dotnet.DotnetRunner then it throws another error as below ...

Could not resolve CoreCLR path. For more details, enable tracing by setting COREHOST_TRACE environment variable to 1

@asif48 Did you try to set COREHOST_TRACE=1 to see what's going on?
