.NET Questions and Solutions

Symptoms
You experience out of memory exception errors on a Web server that has Microsoft ASP.NET 1.1 installed. ASP.NET 1.1 is installed as part of the Microsoft .NET Framework 1.1 and the Microsoft .NET Framework 1.1 Service Pack 1 (SP1).
Resolution
This problem occurs because the MobileCapabilities object does not expire from the cache as expected. You can use an instance of the MobileCapabilities object to read the capabilities of the requesting browser and device.

Symptoms
When a System.EnterpriseServices.TransactionProxyException exception is triggered during a transaction completion, it cannot be caught from other application domains. Instead, you receive a System.Runtime.Serialization.SerializationException exception that resembles the following:

Unhandled Exception: System.Runtime.Serialization.SerializationException: Type ‘System.EnterpriseServices.TransactionProxyException’ in Assembly ‘System.EnterpriseServices, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a’ is not marked as serializable.
Resolution
This problem occurs because the TransactionProxyException exception is not serialized, and then cannot be caught from another application domain.

Symptoms
The following floating-point exception error message might occur for queries that require a “merged” histogram:

Server: Msg 3628, Level 16, State 1, Line 2 A floating point exception occurred in the user process. Current transaction is canceled.
Resolution
A float overflow exception occurs in SQL Server when it combines the histograms for two indexes to handle the cardinality estimation for outer-join operators.

Symptoms
