Previous result of a method call is remembered. Is this related with JIT compiler?

[bin_bin1]

In my code, I use a static method of a class. For example, class name is ABC. The static method name is GetService(). I called the ABC.GetService() twice. The first time it returns null, because the ABC service is not available at that time. However when I call the method the second time, it should return the service, because the service is available already. but the code still retunrs null. If I put a break point before the second time I call the function. I can use code to see the ABC.GetService() returns the service. It seems to me that the code remember the previous result and used it again when it should not. Is there a way to resolve this issue. Any suggestions are greatly appreicated. Best Regards Bin

I suspect your code is broken. The best way to write code like this, is to make your static property check if the return value is null, and if it is, try to populate it, before returning it. Obviously, if you want us to tell us what's wrong with your code, you need to post it.

Thank you very much for your reply. The first time when the function is called. The value is supposed to be null. I don't want to populate the value at that time. I cannot post the code here. It is a very big project. The service is SharePoint shared service. In the beginning, the service is not available. I ran psconfig.exe to create the shared service. I will try to repro this with some simple example. Thank you very much Bin

If you get a different result running and stepping through some program code, I always suspect either a timing issue that depends on external stuff or the optimizer settings when you compile. As to why there's a problem, as mentioned, without code who knows.

You can't post the code to a property ?
