Deadlock Risk Detected with PageProviders
After some further investigation we have realised the following is occuring on all new developers' machines:
- The page provider's ResolveLocalPage method is called.
- When the "DataFactory.Instance.GetPage(this.EntryPoint)" call occurs, the thread moves into EPiServer
- EPiServer calls back into the ResolveLocalPage method - this is as a result of Getting the EntryPoint page
- Deadlock is detected and exception is thrown
We can now understand why the exception is thrown, but what we don't understand is when myself and the other initial developer debug the PageProvider, step 2 above does not result in a call back into ResolveLocalPage.
I believe we have developed the PageProvider in the standard way, if anyone can assist with this then I would be extremely grateful.
Thanks,

I have run into an interesting issue with the page providers we have developed so far. A colleague and myself don’t have any issues with the code base or database, but when a different developer tries to use the page providers (or when we try to deploy it to our local staging server) the following exception gets thrown:
"Deadlock risk detected. Trying to read a page from the same thread that is already trying to read the same page"
The line that it is failing on is trying to execute
Guid entryPointGuid = DataFactory.Instance.GetPage(this.EntryPoint).PageGuid;
in the 'ResolveLocalPage(Guid, out PageReference) method.
If anyone has any ideas on this then please let me know.
Thanks,
Marcus
