We are using Wael hamze tool provided in devops pipeline. On daily basis we register this .dll but getting error of size, below is the error

##[error]"The assembly content size '16783872 bytes' has exceeded the maximum value allowed for isolated plug-ins '16777216 bytes'.

What is the solution on this error. Please inform us asap, we are stuck from few days

You will need to break your plugin into multiple assemblies that are smaller.
