What is the maximum allowable value of \"Max Pool Size\" in a connection string?
Suppose this is my connection string in app.config
You may check with DBA connection limit set in database server
As far as I know - 32767 This is the limit of Sql Server, not .NET
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.
