I'm trying to host my ASP.NET MVC 5 Entity Framework code first project (the project is running perfectly fine on my machine with local db connection strings) on go daddy. I've been getting a few errors and I was able to correct them up until now.
Now I'm getting this error:
CREATE DATABASE permission denied in database 'master'.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.Data.SqlClient.SqlException: CREATE DATABASE permission denied in database 'master'.
I've removed the trust level option in my web.config file because it was creating problems with CAS trust level in the asp.net net parameters of godaddy. My CAS trust level in go daddy is set to full.
My connection strings:
<add name="DefaultConnection"
connectionString="Data Source=ipadress;AttachDbFilename=|DataDirectory|\aspnet-aspProjetFinal-20141211061340.mdf;Initial Catalog=aspnet-aspProjetFinal-20141211061340;Integrated Security=false;User Id=myuser; Password=mypassword;"
providerName="System.Data.SqlClient" />
<add name="monModel"
connectionString="data source=ipadress;initial catalog=GestionClientsContext;Trusted_Connection=True;Integrated Security=false;MultipleActiveResultSets=True;App=EntityFramework;User Id=myuser; Password=mypassword;"
providerName="System.Data.SqlClient" />
I've tried a few things, for example, this:
http://forums.asp.net/t/1742970.aspx?CREATE+DATABASE+permission+denied+in+database+master+
But I'm not sure if I need to delete some lines after adding said line at the top of the code.
My global.asax.cs file:
public class MvcApplication : System.Web.HttpApplication
{
protected void Application_Start()
{
Database.SetInitializer<GestionClientsContext>(null);
Database.SetInitializer(new InitialisationGestionClients());
GestionClientsContext testing = new GestionClientsContext();
testing.Database.Initialize(true);
AreaRegistration.RegisterAllAreas();
FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
RouteConfig.RegisterRoutes(RouteTable.Routes);
BundleConfig.RegisterBundles(BundleTable.Bundles);
//throw new Exception(ConfigurationManager.ConnectionStrings["DefaultConnection"].ConnectionString);
}
I clearly need some guidance, I've already spent a lot of hours just trying to get it online ! Let me know what you think ! Thanks !
What you asked for Dan:
public class InitialisationGestionClients : System.Data.Entity.CreateDatabaseIfNotExists<GestionClientsContext>
{
protected override void Seed(GestionClientsContext context)
{
base.Seed(context);
var lesClients = new List<Clients>
{
new Clients{nom="Finch", prenom="Paul",dateInscription=DateTime.Parse("2014-01-10"),adresse="911 De la Commune", email="test#hotmail.com", solde=0,commentaires="Juste un test"}
};
lesClients.ForEach(s => context.Clients.Add(s));
context.SaveChanges();
var lesFacures = new List<Factures>
{
new Factures{motif="Programmes janvier 2014", montant=25,dateFacturation=DateTime.Parse("2014-01-10"),statusPaid=false, ClientsId=1}
};
lesFacures.ForEach(s => context.Factures.Add(s));
context.SaveChanges();
var lesPaiements = new List<Paiements>
{
new Paiements{montant=25,datePaiements=DateTime.Parse("2014-02-10"), ClientsId=1}
};
lesPaiements.ForEach(s => context.Paiements.Add(s));
context.SaveChanges();
}
}
UPDATE: I've gotten the site to "run" if I can use this word. I can now access the application online BUT as soon as I try to login or create a new user, using the MVC login feature, I get the following error:
CREATE DATABASE permission denied in database 'master'.
I already got that error before when the application was trying to load but I didn't get it since I change the trust level to FULL. I'm not sure I'm following this one ! I'm just trying to login why is he trying to create anything at all !

I have just added SQLite to my asp.net webApi project, and am having trouble working out how get the path to the App_Data folder to pass to DbContextOptionsBuilderUseSqlite
I have the following in the web.config I have a link to an external a config file with the conenction string...
<connectionStrings configSource="config\connectionStrings.config"/>
and in there I have...
<connectionStrings>
<add name="MyDatastore"
connectionString="DataSource=./App_Data/test.sqlite" />
</connectionStrings>
And in my DbContext.OnConfiguring I Have....
protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)
{
if (!optionsBuilder.IsConfigured)
{
string path = WebConfigurationManager.ConnectionStrings["MyDatastore"].ConnectionString;
optionsBuilder.UseSqlite(path);
}
}
The path is correctly retrieved (I can see I get the path as configured on connectionStrings.config
so ./App_Data/test.sqlite is passed to optionsBuilder.UseSqlite(path).
However, I get the following error...
SQLite Error 14: 'unable to open database file'.
If I use just connectionString="DataSource=test.sqlite" /> then it seems to magically find the file in the App_Data folder, when I ran on my dev machine in debug, but I had problems on another machine (release build). I assume it is the path, though all I get back is 'unable to open database file'.
I also tried..
connectionString="DataSource=|DataDirectory|test.sqlite" />
This gives me a Illegal characters in path error.
The following does work (full path)
connectionString="d:\0\test.sqlite" />
But I want to be able to use relative paths, eg maybe even .\datastore\test.sqlite.
Does any one have any ideas on this?
Thanks in advance
You'll have to fix up the relative paths at runtime:
var builder = new SqliteConnectionStringBuilder(connectionString);
builder.DataSource = Path.GetFullPath(
Path.Combine(
AppDomain.CurrentDomain.GetData("DataDirectory") as string
?? AppDomain.CurrentDomain.BaseDirectory,
builder.DataSource);
connectionString = builder.ToString();
Works perfectly for me.
protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)
{
var dataSource = Path.Combine(System.Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments), "siteDB.db");
optionsBuilder
.UseSqlite($"Data Source={dataSource};");
}
Note: This solution was tested for .Net Core 5, and one can presume it will work on 2.x, 3.x, 5
If you want to use a diferent project than the one provided when you started, you have to specify the correct path ("Data Source = ..\\MyApplication.DAL\\sqliteDatabase.db") in the appsettings.json.
In this presented case, you don't even need to write the method OnConfiguring(DbContextOptionsBuilder optionsBuilder) in the ApplicationDbContext.cs.
You have a full setup bellow (Startup & appsettings.json).
My project structure:
-> MyApplication (solution)
-> MyApplication.UI (initial project of the solution)
-> MyApplication.BL (project)
-> MyApplication.DAL (project)
Inside Startup.cs
public void ConfigureServices(IServiceCollection services)
{
//... other services
services.AddDbContext<ApplicationDbContext>
(x => x.UseSqlite(Configuration.GetConnectionString("SqliteConnection")));
//.... other services and logic
}
In appsettings.json :
"ConnectionStrings": {
"SqliteConnection": "Data Source = ..\\MyApplication.DAL\\sqliteDatabase.db"
}
Works for me on linux, .net core 5.
var builder = new SqliteConnectionStringBuilder("Data Source=MyDatabase.db");
builder.DataSource = Path.Combine(AppDomain.CurrentDomain.BaseDirectory, builder.DataSource);
services.AddDbContext<MyContext>(o => o.UseSqlite(builder.ToString());
Assumes database is in the bin directory, e.g. MyProject/bin/Debug/MyDatabase.db or MyProject/bin/Release/MyDatabase.db.
If you are a .Net Core backend developer who use sqlite, make sure to use below code example. Otherwise SQLite Error 14: 'unable to open database file' error will come.
Startup.cs
var baseDirectory = System.Environment.GetFolderPath(Environment.SpecialFolder.CommonApplicationData);
string dbPathSystemLog = Path.Combine(baseDirectory, "CAMSCoreSystemLog.db");
SystemLogDBContext.cs
public class SystemLogDBContext : DbContext
{
public SystemLogDBContext(DbContextOptions<SystemLogDBContext> options) : base(options)
{
Database.EnsureCreated();
}
}
This line will create the Db if not exist
Database.EnsureCreated();
I was struggling two days. This will help someone.
I'm getting some issues with SignalR (1.1.2) trying to create a basic realtime chat setup and after spending about a week on it (including trawling through the SignalR source) I'm sort of at the end of what I can try...
I have (I think) a rather complicated SignalR setup consisting of:
Load balanced servers
Redis message bus
Two sites on each server (ASP.NET Webforms VB.NET desktop site and MVC3 C# mobile site)
Each of the sites includes the hub of itself and the other site, so each page can send messages to each site.
Looking into the Chrome inspector (in this example on the mobile site), the hubs are both loaded, the negotiate step for mobile is successful but the connect attempt fails after 3 seconds with the error:
EventSource's response has a MIME type ("text/html") that is not "text/event-stream". Aborting the connection.
which is of course our custom 500 error page after Microsoft.Owin.Host.SystemWeb has thrown:
The connection id is in the incorrect format.
Once this happens, most of the time this will then get into some sort of weird loop where it will continue to throw hundreds of these errors and send off lots of pings followed by a longPolling connect
The solution works perfectly well in my development environment (single IIS instance) but moving to the load balanced test environment is where I see the errors.
I don't know if there's anything else I can add that may help but I'm happy to add it.
I've added the following to the web.config files on both sites:
<validation validateIntegratedModeConfiguration="false"/>
<modules runAllManagedModulesForAllRequests="true"/>
and
<add name="Access-Control-Allow-Origin" value="*"></add>
<add name="Access-Control-Allow-Headers" value="Content-Type" />
The global.asax files have:
protected void Application_Start()
{
AreaRegistration.RegisterAllAreas();
RegisterGlobalFilters(GlobalFilters.Filters);
RegisterRoutes(RouteTable.Routes);
RedisScaleoutConfiguration redisConfig = new RedisScaleoutConfiguration([redisIP], [port], String.Empty, "Name");
redisConfig.Database = 9;
GlobalHost.DependencyResolver.UseRedis(redisConfig);
}
public static void RegisterRoutes(RouteCollection routes)
{
routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
HubConfiguration hubConfig = new HubConfiguration();
hubConfig.EnableCrossDomain = true;
hubConfig.EnableDetailedErrors = true;
RouteTable.Routes.MapHubs(hubConfig);
<snip>
}
The JS code I have is along the lines of:
function setUpSignalR() {
//Set up the connections
webConnection = $.hubConnection(pageInfo.webUrl);
mobConnection = $.hubConnection(pageInfo.mobUrl);
//Get the hubs for web and mobile
webHub = webConnection.createHubProxies().messagingHub;
mobHub = mobConnection.createHubProxies().messagingHub;
//Hook up the call back functions
<snip>
//Now, start it up!
mobConnection.logging = true;
mobConnection.start().done(function() {
mobHub.server.joinConversation(pageInfo.conversationGuid, "mobile").fail(function (error) { console.log('JoinConversation for mobile connection failed. Error: ' + error); });
webConnection.start().done(function() {
webHub.server.joinConversation(pageInfo.conversationGuid, "mobile").fail(function (error) { console.log('JoinConversation for web connection failed. Error: ' + error); });
});
});
}
From the SignalR troubleshooting document:
"The connection ID is in the incorrect format" or "The user identity
cannot change during an active SignalR connection" error
This error may be seen if authentication is being used, and the client
is logged out before the connection is stopped. The solution is to
stop the SignalR connection before logging the client out.
I'm playing around with asp.net for the first time. I want to use it with a MySQL database because this is what is offered by my hosting service and I don't want to upgrade/change services. I'm using visual web developer 2010 express. I created an MVC 4 project from the default template. The template created the ASP.NET Simple Membership objects which is what I'm trying to get working. The project builds and runs correctly when using the default database connection string. When I change the web.config file to point to MySQL I get the following error when I attempt to navigate to any of the pages in the account folder.
You have an error in your SQL syntax; check the manual that
corresponds to your MySQL server version for the right syntax to use
near 'IDENTITY,
RoleName nvarc' at line 2
When I open the MySQL work bench and connect to the local server I notice that the database has been created. If I drop the DB and run the app again it gets recreated. I'm note sure if it was created correctly or if the entire database was created but there is something there.
Obviously there is an issue with the SQL syntax that is created by the Entity Framework. Do I need to add something to the web.config file to tell it what syntax it should use when creating the queries?
I've been searching for an answer to this for the past two days. any help pointing in the right direction would be appreciated.
I'm using mysql server version 5.5.27. and connector 6.5.4.0
here is the mysql part of my web.config file:

}
Try to modify the source of the SMP and remove the syntax specific to ms sql server.
The role provider is still defaulting to the standard ASP one which is expecting a SQLServer DB on the end of the connection, "Identity" is SQLServerese for "autoinc".
You can set the default providers in the web.config like this:-
<configuration>
<system.web>
<profile defaultProvider="MySQLProfileProvider"></profile>
<roleManager defaultProvider="MySQLRoleProvider"></roleManager>
</system.web>
</configuration>
This is supposed to just work. I've read all the articles I could find via google on the topic, tried to copy as much as I could from other articles on both StackOverflow and CodeProject and others, but regardless of what I try - it doesn't work.
I have a silverlight application that runs fine using Windows Authentication.
To get it running under Forms Authentication I've:
Edited the web.config file to enable Forms Authentication (and delete the Windows Authentication configuration):
<authentication mode="Forms">
<forms name=".ASPXAUTH" loginUrl="logon.aspx" defaultUrl="index.aspx" protection="All" path="/" timeout="30" />
</authentication>
Created a standard logon.aspx and logon.aspx.cs code behind page to take a user input name and password, and create a authentication cookie when the logon was successful, and then redirected the user to the root page of the web site, which is a silverlight application:
private void cmdLogin_ServerClick( object sender, System.EventArgs e )
{
if ( ValidateUser( txtUserName.Value, txtUserPass.Value ) )
{
FormsAuthentication.SetAuthCookie(txtUserName.Value, true);
var cookie = FormsAuthentication.GetAuthCookie(txtUserName.Value, true);
cookie.Domain = "mymachine.mydomain.com";
this.Response.AppendCookie(cookie);
string strRedirect;
strRedirect = Request["ReturnUrl"];
if ( strRedirect == null )
strRedirect = "index.aspx";
Response.Redirect( strRedirect, true );
}
}
So the redirect after successfully logging in launches my silverlight application.
However the user is not authenticated when executing the Silverlight startup code:
public App()
{
InitializeComponent();
var webContext = new WebContext();
webContext.Authentication = new FormsAuthentication();
ApplicationLifetimeObjects.Add( webContext );
}
private void ApplicationStartup( object sender, StartupEventArgs e )
{
Resources.Add( "WebContext", WebContext.Current );
// This will automatically authenticate a user when using windows authentication
// or when the user chose "Keep me signed in" on a previous login attempt
WebContext.Current.Authentication.LoadUser(ApplicationUserLoaded, null);
// Show some UI to the user while LoadUser is in progress
InitializeRootVisual();
}
The error occurs in the ApplicationUserLoaded method, which always has its HasError property set to true on entry to the method.
private void ApplicationUserLoaded( LoadUserOperation operation )
{
if((operation != null) && operation.HasError)
{
operation.MarkErrorAsHandled();
HandlerShowWebServiceCallBackError(operation.Error, "Error loading user context.");
return;
}
...
}
The error reported is as follows - from what it appears to me is that the user isn't considered authenticated on entry to the silverlight app, so it is directing the code to try to return the logon page, which is returning data unexpected by the silverlight app:
An exception occurred while attempting to contact the web service.
Please try again, and if the error persists, contact your administrator.
Error details:
Error loading user context.
Exception details:
Load operation failed for query 'GetUser'. The remote server returned an error: NotFound.
Any ideas?
Based on everything I read, this is supposed to be pretty simple and just work - so I'm obviously making a very basic error.
I'm wondering if after I authenticate the user on my logon.aspx web page, I need to somehow pass an authenticated WebContext instance over from the logon page to my silverlight application instead of creating a new instance in the silverlight app startup code - but have no idea how to do that.
Appreciate any or all suggestions.
I suspect the Response.Redirect("...", true);
According to this article you should pass false to keep the session.
I have a WCF service, hosted in IIS, which I require to impersonate the annon account.
in my Webconfig
<authentication mode="Windows"/>
<identity impersonate ="true"/>
Testing the following, with vs2008
public void ByRuleId(int ruleId)
{
try
{
string user = WindowsIdentity.GetCurrent().Name;
string name = Thread.CurrentPrincipal.Identity.Name;
........
//get the data as a string.
using (FileStream fs = File.Open(location, FileMode.Open))
using (StreamReader reader = new StreamReader(fs))
{
rawData = reader.ReadToEnd();
}
}
catch.....
}
this works. however if I add impersonation attribute
[OperationBehavior(Impersonation=ImpersonationOption.Required)]
public void ByRuleId(int ruleId)
this does not work with the error message
"Either a required impersonation level was not provided, or the provided impersonation level is invalid."
a little poking around I noticed the first way was authenticated by Kerboros and the second way just failed on authentication type
I am using the WCF client tool, to pass my credentials. this seems to be working.
Check the 'TokenImpersonationLevel' of identity of the current thread; you'll need it to be at least 'Impersonation' to perform operations on the machine that the service is running on.
Typically, if you are using a proxy client, you'll need to set the 'TokenImpersonationLevel' of the client:
http://www.devx.com/codemag/Article/33342/1763/page/4
the main goal of this was to get anon access, even tho MattK answer was a great help.
here is what i did to do so.
on the implementation of the WCF contract I added the
[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Required)]
public class TransferFile : ITransferFile
and in the web.config
<system.serviceModel>
<serviceHostingEnvironment aspNetCompatibilityEnabled ="true" />
after this i was able to impersonate the anon account
