When a stored procedure I'm running executes mini-profiler throws a null reference and causes my application to stop. In this instance the SP doesn't return anything.
Here is the stacktrace:

I finally figured out the solution to my question above. The error was happening on a legacy webforms application that was using sql data source for the grid. The sql datasource was using the 'ProviderName' property. Once I removed this property everything started working.
Had the same problem: NRE from application start. Exception occures at MvcMiniProfiler.MiniProfiler.AddSqlTiming(SqlTiming stats)
Problem reason: database call in Application_AuthenticateRequest()
Problem solution: MiniProfiler.Start(); moved to the end of Application_AuthenticateRequest() method.

I have a simple but tough problem.
I am trying to add an user to a team through user interface, however I'm getting SQL Time Out for some users.
I got no plugins firing on association request. I also did not find any familiarity between the ones I am getting this error.
I have even turned the trace log on which did not give me much more details.
Following the error log generated by tracing tool.

I recently publish my ASP.Net MVC 3 web application (Entity Framework 4.1 for Data Persistence) to a live server. The application is located on one web server and the database (SQL Server 2008) is located on another separate server.
The site has only been live a few days with very few hits, and because of this there are very few records contained within the database tables (10- 20 max).
I also have ELMAH (Error Logging Modules and Handlers for ASP.NET) integrated into the site and I have received a few instances of the following error already
System.Data.SqlClient.SqlException: Timeout expired. The timeout
period elapsed prior to completion of the operation or the server is
not responding.

The occasions where this error has happened have been due to SELECT queries. These select queries are very simple, ie,
Select col1, col2, col3 from table where col1 = 1
And as I have stated, there is very little data within the database, so it isn’t as if the queries are pulling back 100’s of records.
I have done some research into this using both the Internet and Stackoverflow. Some people suggest to increase the dbContext CommandTimeout Property, however, I don’t understand why I should need to do this. Yes, if I were pulling back loads of records, but as I have said, these are simple SELECT statements pulling back 1-5 records at the most.
I also know that developers need to keep an eye on the SQL generated by the Entity Framework, so, I downloaded and ran this trial version http://www.datawizard.com in order to get a look at the SQL being created for the Entity Framework SELECT queries that were causing a problem. Again, the profiler showed these queries to be very simple syntax, so I don’t think that is the problem.
I am beginning to think maybe it has something to do with my database and web application being on separate servers, however, I am out of ideas!
Please if anyone can help or advise me with this issue, it would be greatly appreciated.
Thanks everyone.
We have a weird situation going on here. We have setup a local installation of NuGet gallery (the same code that powers http://Nuget.org). The IIS and the DB are on the same box. The IIS App pool has been configured to run under a domain user who is the local admin on the box as well and has the "right to logon as a service" rights. Now when someone (after succesfully logging in) tries and upload a package, the upload package business takes ages and eventually throws up the "The underlying provider failed to open" error

Interestingly if I switch IIS App Pool to run under the built in "LocalSystem" account all these problems goes away. The domain user we want to use has been temporarily setup as the database owner for NuGetGallery database but it isn't helping.
Can anyone suggest what setting/configuration we might be missing here?
This was due to ambient transactions going on within the code. The code relied on TransactionScope classes to manage various transactions which were getting in a jam when they got nested. Things turned particularly bad if someone tried uploading a package which was more than around 10MB in size. Once we tweaked the MSDTC on the boxes the application started behaving slightly properly. However it was still intermittently getting deadlocked within its own transactions so for now we have decided to remove transactions from the package upload bit.
For anyone else who gets into this problem I would recommend either of these two
Comment out any reference to TransactionScope in
Services\PackageService.cs (method CreatePackage, line 48)
using (var tx = new TransactionScope())
{
using (var stream = nugetPackage.GetStream())
{
UpdateIsLatest(packageRegistration);
packageRegistrationRepo.CommitChanges();
packageFileSvc.SavePackageFile(package, stream);
tx.Complete();
}
}
And in Controller\PackageController.cs method VerifyPackage(bool? Listed) line 501
using (var tx = new TransactionScope())
{
package = packageSvc.CreatePackage(nugetPackage, currentUser);
packageSvc.PublishPackage(package.PackageRegistration.Id, package.Version);
if (listed.HasValue && listed.Value == false)
packageSvc.MarkPackageUnlisted(package);
uploadFileSvc.DeleteUploadFile(currentUser.Key);
tx.Complete();
}
2 Uncomment those lines and follow the approach mentioned here http://blogs.msdn.com/b/dbrowne/archive/2010/05/21/using-new-transactionscope-considered-harmful.aspx
Basically create a transactionscope which can work well with SQL Server. Create a new class in the InfraStructureFolder, call it TranscationUtils and copy the code in there. Then the using blocks would look like
using (var tx = new TransactionUtils.CreateTransactionScope()){
//cod here
tx.Complete();
}
However this second approach can result in another server error which again relates to the default time outs you can specify for TransactionScope. We have personally decided to go with approach 1 and comment out all TransactionScope references for now.
I have constructed a simple query to return a Users Team membership (N: N relationship). This works fine for all users, however, when I add a where clause to restrict to a specific user it throws a fault exception (see stack trace below).
Strangely this works fine with "where Users.FullName.StartsWith("Alex")". Does the Dynamics CRM SDK LINQ implementation not support Guides in where clauses?
Any advice?
Example code
using (var service = new OrganizationService("Xrm"))
{
using (var xrm = new XrmServiceContext(service))
{
var AlexUser = xrm.SystemUserSet.Where(p => p.FullName.StartsWith("Alex")).First();
var AlexID = AlexUser.Id;
var Test =
from Users in xrm.SystemUserSet
join TeamMemberships in xrm.TeamMembershipSet on Users.Id equals TeamMemberships.SystemUserId
join Teams in xrm.TeamSet on TeamMemberships.TeamId equals Teams.Id
where Users.Id == AlexID // <-- problematic where clause
orderby Users.FullName
select new
{
FullName = Users.FullName,
UserID = Users.Id,
TeamName = Teams.Name
};
var Test1 = Test.ToList();
}
}

Instead of Users.Id, try Users.SystemUserId. Similarly, instead of Teams.Id, try Teams.TeamId.
As for the reason why this works, I'm not aware of any documentation that states this, but because entities in the generated early-binding file inherit from Entity, they necessarily have an Id property. However, because the early-bound OrganizationServiceContext maps entity attributes directly to the CRM database, the tables of which don't contain an Id column, using the Id attribute with the LINQ provider won't work, so you'd have to use the actual database/schema names.
I've got an instance of Dynamics CRM 4.0 with some weird errors. If I close a Case and then try to reactivate it I get the error "The object cannot be updated because it is read-only". This is simple, built-in CRM functionality that works fine on other instances. I get the same error if I try to convert a Quote to an Order - I believe it's trying to update the Quote, which has been "closed" by then. What's wrong and how do I fix it?

Try disabling your onload and onsave code to see if that is causing any problems. To quickly and temporarily disable the events, open the dialog box where you paste in your onload/onsave code and uncheck 'Event is enabled'. Then save the form and publish the entity. Does the error still occur?
