Hi,

I deployed some templates which were working fine till the point where I created a new dll in my project.

As soon as I compiled my solution, I got the error below nothing more than that.

Error	1	The type or namespace 'VisualStudio' doesn't exist in the namespace 'Microsoft' ( an assembly is missing  ?)

I moved back till the point where it was working but nothing changed. 2 messages looking as above keep pointing on each of my template.

If someone already met this error or if someone has any idea,

By the way I try to fix it by adding some assembled beginning with

Microsoft.VisualStudio.something

but nothing does.

Hoping to have a feedback from you guys,

Thx

Check the references in your project, and also check the source module that produces the error message for references as above. Without seeing some of your code where the error occurs it is difficult to be more specific.

I must get a clever new signature for 2011.

Thx Richard,

To be more precise, I get 2 errors similar to the one below per template.

Error	1	The type or namespace 'VisualStudio' doesn't exist in the namespace 'Microsoft' ( an assembly is missing  ?)

There is 2 errors messages which are pointing on this part.

<#@ template language="C#" debug="false" hostspecific="true"#>
<#@ include file="EF.Utility.CS.ttinclude"#>
<#@ output extension=".cs"#>
<#@ Assembly Name="System.Core, Version=4.0.0.0, Culture=neutral" #> 
<#@ Assembly Name="Microsoft.CSharp, Version=4.0.0.0, Culture=neutral" #>

The rest of the errors messages are pointing onother templates but the line pointed are not existing.

I guess it's coming from somewhere else.

I was expecting to fix it with the 2 Assembly lines specifing my version of dotNEt but without success.

References of this DLL:

-envdte
-Microsoft.Build
-Microsoft.CSharp
-System
-System.Core
-System.Data
-System.Data.DataSetExtensions
-System.Data.Entity
-System.Data.Entity.Design
-System.Runtime.Serialization
-System.Security
-System.Xml
-System.Xml.Linq

To refresh, my errors came up when I've added a new dll. Just after that I unloaded it in order to come back in a normal mode.

This errors keep going on.

I still working on,

In the same time, I created a small project with the same content in order to know if it was coming from my code.
And it works, therefore it's not my code.

Weird error....

Do you need more details?

I think with this it's enough.

I keep seeking without success.

I really need of your help guys,

Thx by advance Wink | ;)

Sorry, but this looks like an ASP.NET issue, I suggest you try that forum.

It's not. That's the way that T4 templates look.

Actually, they are really powerful, and very useful for mapping out boiler plate code. Colin Eberhart posted an excellent example here[^] on Code Project.

Let me correct those downvotes. I'm not sure who thought this part of the thread should be downvoted, but I bet I can compensate for them.

Did you get your issue resolved? I think you need to right click on references, click add, click extensions and scroll down to the assembly with the classes you need. Also after you build open the bin directory and make sure that assembly is in the directory.

I assume you are trying to create an app that uses the templates outside of visual studio?

Curvature of the Mind now with 3D

Writing XML file from threads - URGENT -

8-Mar-11 21:36

Still not resolved.

So far once my code is generated I remove the code inside my template.

As I said in my first post the assembly required is VisualStudio.

Error	1	The type or namespace 'VisualStudio' doesn't exist in the namespace 'Microsoft' ( an assembly is missing  ?)

I check several time but there is nothing looking like.

Although the errors target on my template, I almost assume that it's not coming from there because It was working before.

Below my template perhaps there is something obvious:

<#@ template language="C#" debug="true" hostspecific="true"#>
<#@ include file="EF.Utility.CS.ttinclude"#>
<#@ output extension=".cs"#><#

Hi guys

what zup ???? Poke tongue | ;-P

i have a big problem with thread and xml......i'm trying to write in a xml file from thread so i created a class i called them "Xmlwriter"

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Xml;


namespace xmlWriter_test
{
    class Xmlwriter
    {
        public XmlTextWriter txtWriter { get; set; }
        public string xmlPath { get; set; }
        public Object thislock = new Object();

        public Xmlwriter(string path)
        {
            xmlPath = path;
            txtWriter = new XmlTextWriter(path, null);
        }
        public void writeElement(string element, string data)
        {
            try
            {
                lock (thislock)
                {
                    //txtWriter.WriteStartDocument();
                    txtWriter.WriteStartElement(element);
                    txtWriter.WriteString(data);
                    txtWriter.WriteEndElement();
                    Console.WriteLine("good job !!");
                    //txtWriter.WriteEndDocument();
                }
            }
            catch (InvalidOperationException e)
            {
                Console.WriteLine("erreur :" + e.Message);
            }
        }
        public void startDocument()
        {
            txtWriter.WriteStartDocument();
        }
        public void endDocument()
        {
            try
            {
                txtWriter.WriteEndDocument();
            }
            catch (ArgumentException arg)
            { Console.WriteLine("erreur :" + arg.Message); }
        }
        public void closeDocument()
        {
            txtWriter.Close();
        }
    }
}

and this is my Main class

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Xml;
using System.Data.OleDb;
using System.Data;
using System.Threading;

namespace xmlWriter_test
{
    class Program
    {
        static int i = 0;
        static Xmlwriter wifixmlWriter = new Xmlwriter(@"D:\wifi_test.xml");

        static void Main(string[] args)
        {
            //start document
            wifixmlWriter.startDocument();
            Thread th = new Thread(new ThreadStart(background));
            Console.WriteLine("starting thread..."); 
            th.Start();

            //end 
            th.Join();
            wifixmlWriter.endDocument();
            Console.WriteLine("press any key to quit");
            Console.ReadKey();
        }

        static public void background()
        {
            //just looop xD
            while (i<50)
            {
                Console.WriteLine("i = {0}", i++);
                //writing in the xml file
                wifixmlWriter.writeElement("hello", "i = " + i);
 
            }
        }
    }
}

that's work for the first iteration and bug after that xD i don't know why .....
and here is what i get at the end ^^
le jeton StartElement dans l'état Error générera un document XML non valid
in english = " the startElement generate an invalid XML document !!!!!!

I'll get round to looking at your code, but there are about 173 items ahead of it in my priority list: Yours is just after "pick my nose" and "shave the cat".

Real men don't use instructions. They are only the manufacturers opinion on how to put the thing together.

Why are you running the XmlWriter in a separate thread? Try removing all the thread related code and run it as a normal app to see whether that works.

thx for answers Smile | :)

that's work without thread but i must do it in tread xD ...... (this code is just for test ....my real app work in thread to get URL from navigators and i have to write the result in xml file )

or my be i should create a delegate nd invoke them from thread ????

Richard MacCutchan7-Mar-11 22:28

Looking quickly at your code I do not see any synchronization between the main and background thread, perhaps you are breaking in to the worker thread too soon.

moums7-Mar-11 22:37

7-Mar-11 22:37

yes..i think so .... im wondering if i can force the execution of the 3 instructions writeStartElement - writeString - writeEndElement in the same iteration Frown | :(

............ do u know how to do dat ^^

Richard MacCutchan8-Mar-11 0:03

Look at your code:

static void Main(string[] args)
{
    //start document
    wifixmlWriter.startDocument();
    Thread th = new Thread(new ThreadStart(background));
    Console.WriteLine("starting thread...");
    th.Start();

    //end
    th.Join();
    wifixmlWriter.endDocument();
    Console.WriteLine("press any key to quit");
    Console.ReadKey();
}

You are breaking into a thread and arbitrarily ending the document. You need to synchronise with the thread so that endDocument() is not called until all the elements have been written.
