Build and run the azure function but I get an error message

[Haroon921]

Hello Mark,

I am preparing for a partner workshop using the following link:
https://github.com/AzureCosmosDB/labs/blob/master/dotnet/labs/08-change_feed_with_azure_functions.md#create-an-azure-function-to-consume-cosmos-db-change-feed

I need to build and run the azure function but I get an error message.

C:\labs\Lab08\ChangeFeedFunctions>dotnet run
Unable to run your project.
Ensure you have a runnable project type and ensure 'dotnet run' supports this project.
A runnable project should target a runnable TFM (for instance, net5.0) and have OutputType 'Exe'.
The current OutputType is 'Library'.
I attempted to include the following


Exe
netcoreapp3.1
v2


then I get the following
C:\labs\Lab08\ChangeFeedFunctions>dotnet run
CSC : error CS5001: Program does not contain a static 'Main' method suitable for an entry point [C:\labs\Lab08\ChangeFeedFunctions\ChangeFeedFunctions.csproj]
The build failed. Fix the build errors and run again.
