What is maximum allowable value of “Max Pool Size” in sql connection string

Question

What is the maximum allowable value of \"Max Pool Size\" in a connection string?

Suppose this is my connection string in app.config

Answer 1

There is no documented limit on Max Pool Size. There is however an exact documented limit on maximum number of concurrent connections to a single SQL Server (32767 per instance, see http://msdn.microsoft.com/en-us/library/ms143432(v=SQL.90).aspx).

A single ADO.NET pool can only go to a single instance, so maximum effective limit is therefore 32767.
