FIX: The number of concurrently running orchestrations in BizTalk Server reaches 250, and you experience poor performance after you install the .NET Framework 2.0 SP1 or a later version of the .Net Framework
- You can monitor the number of concurrently running BizTalk orchestrations in Performance Monitor by using the "XLANG/s Orchestrations" - "Running orchestrations" counter. For more information, see the More Information section.
- Because of certain file dependencies, the .NET Framework 3.5 and the .NET Framework 3.0 SP1 automatically install the .NET Framework 2.0 SP1.Also, the .NET Framework 3.5 SP1 automatically installs the .NET Framework 2.0 SP2. Therefore, this issue also occurs after you install the following versions of the .NET Framework:
- .NET Framework 2.0 SP2
- .NET Framework 3.0 SP1
- .NET Framework 3.5
- .NET Framework 3.5 SP1
