Is there any suggestion for PostgreSQL to add type Nvarchar?
This is the error that I am getting:
Npgsql.PostgresException (0x80004005): 42704: type "nvarchar" does not exist

Thank you.
"National" string data types are a vestige from the dim and distant past when people still used single-byte encodings like ISO 8859-1 or Windows-1252.
Nowadays we store data using UNICODE encodings, in the case of PostgreSQL, UTF-8. Since you can store any character that way, there is no need for a special data type.
This error occured to me when my last migration (which the update-database command uses) was not for a PostgreSQL connection.
You can try this:
create a new migration with add-migration <name>
clear the database with update-database 0
apply the newly created migration on the database with update-database
In my case, first I was using SQL Server as DB and changed to PostgreSQL. Old migrations were caused the problem type "nvarchar" does not exist. Deleted old migrations and created new migration, updated everything worked fine.

Handling *.aspx is not defined in iis. go into
IIS manager --> Default Website --> handler Mapping
Check if you have a mapping for aspx... ideally you should see 2 mappings for .aspx...
you can also use the command line to get the info by the following:

I am getting an error using the RegisterExternalLogin control from the Visual Studio templates. After choosing login from Twitter, Twitter seems to process the login ok and then tries to load the response page and then the error occurs.
The error seems to be related to EntityFrameworks after the login method being called from the Microsoft.Aspnet.Membership.OpenAuth dll but that's about all I know.
Does anybody know how to resolve this?
Here is the error message:

Solution: Make sure you're using latest v 2.0.0 Microsoft.AspNet.Membership.OpenAuth package, not 1.0.1.
I've written an ASP.NET 4.0 application that is using a SQL Server CE 4.0 database. This is all working on my development environment using Medium Trust (same trust config as the hoster). On this machine, I've gone through the install process (downloaded and installed the MSI). I'm now trying to deploy this solution to my web hoster.
The code that is running is (this is a straight out copy of the Altairis Membership Provider:
using (HostingEnvironment.Impersonate())
using (var db = this.connectionString.CreateDbConnection())
using (var cmd = this.CreateDbCommand("SELECT PasswordHash, PasswordSalt FROM $Users WHERE UserName = #UserName AND IsApproved = 1", db))
{
cmd.AddParameterWithValue("#UserName", username);
db.Open();
// Validate password
using (var r = cmd.ExecuteReader()) { .. snip.. }
}
In the instance above, db is DbConnection, and cmd is DbCommand

I've used a decompiler to look through the code, and it seems that the internals of SQL Server CE are looking for a registry entry and then trying to do a code Assert().
Is it possible to use SQL Server CE 4.0 in a partial trust environment, by just \bin deploying the DLL ??
Yes, provided your hoster allows it - it is allowed by default in ASP.NET 4.0. Make sure you use assembly version 4.0.0.0 (and not 4.0.0.1). Read more here: http://erikej.blogspot.com/2011/10/sql-server-compact-40-under-aspnet.html
I'm using some 3rd party software that's failing. Their API is wrapped in a ASP web service.
The call stack tells me that it needs maybe MySQL.Data.DLL or something (not sure exactly) in the correct directory. So I'm wondering where that directory would be. The Web Server is IIS.
Here is the call stack:

I needed to copy MySQL.data.dll to the bin directory of my web service application directory. I also added the config key to the web.config.
We've run into some issues with ASP.NET MVC 3 AntiForgeryToken HTML helper when having a custom configured MachineKey in Web.Config. The error is easy to reproduce if you change your MachineKey to the following (taken from Microsoft HowTo-guide on how to configure machine key).
<machineKey
validationKey="21F090935F6E49C2C797F69BBAAD8402ABD2EE0B667A8B44EA7DD4374267A75D7

validation="SHA1"
decryption="AES"/>
The exception thrown by AntiForgeryToken is as follow:
[IndexOutOfRangeException: Index was outside the bounds of the array.]

Is this a bug in the ASP.NET MVC 3 Html Helper to generate the AntiForgeryToken? Or am I missing something in regards to configuring machine keys?
It looks like I screwed up the keys - using http://aspnetresources.com/tools/machineKey I was able to generate a valid machineKey config section.
