After Update 14.2.507.122 my web app crash with this error:

Same value has already been added.

Type: ArgumentException

next Question:

Why the Xafari.FX use a Output in Windows\temp\ Folder? ( at Xafari.GeneratedXF.GeneratedXFModule.RegisterDC() in c:\Windows\Temp\szpktufs.0.cs:line 20 )

a restart of the Server will get the App online. A normal Restart of IIS ( iisrest ) will not work.

Hello Lars,

 

To start I can advise you to remove the contents of the following folders:

C:\Windows\Microsoft.NET\Framework\v4.0.30319\Temporary ASP.NET Files

C:\Users\USER_NAME\AppData\Local\Temp\

C:\Windows\Temp\

 

Please, inform us of your results.

 

Thanks, Sasha.

Question:

Why u use the the Windows\Temp Folder instead of C:\Windows\Microsoft.NET\Framework\v4.0.30319\Temporary ASP.NET Files ?

the ASP Folder will be auto cleanup during Start of a ASP net App.. the WIndows\Temp folder not.

Pls fix this asap.

Hello Lars,

 

I apologize for this late response.

 

This problem can be caused by several reasons. We will verify all solutions independently.

If we wouldn't find a solution – we will list all of the reasons tomorrow, so you could check them yourself.

Hi Lars,

 

Generation of files in the folder c:\Windows\Temp doesn't entail the occurrence of this exception.

Dll will be generated in a different folder in the following versions Xafari Framework.

 

But I can't give a definite answer about the origin the exception from Stack trac.

Please send us the contents of the file c:\Windows\Temp\r5izhhis.0.cs to explore this exception.

 

Thanks, Sasha.

Hi,

 

If you don't want to use the Windows\Temp Folder,
you can override next method at your WebApplication:

protected override string GetDcAssemblyFilePath()
{
return Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.UserProfile), "AppData\\Local\\Temp\\Xafari", this.ApplicationName, Path.GetRandomFileName());
}

 

Please, inform us of your results.

Regards, Sasha.

Dear Sasha,

after i update last XAFARI Version 14.2.607.127 i get a new / old Problem in WEB.APP

this occourse everytime on the same WebServer our WebAPP is installed twice. once a PROD ( different DB )
and once as Test .

Question: WHY your Xafari.XF.EntityGenerator.GetXFAssembly()
USE Windows\Temp Folder

instead of ASP.Net temporary C:\Windows\Microsoft.NET\Framework\v4.0.30319\Temporary ASP.NET Folder ? Here the Files live in different Folders for each WebAPPRoot?

I hope for a FAST Fix

Regards Lars

i have try to do this in web.application.dll

protected override string GetDcAssemblyFilePath()
{
return Path.Combine(System.IO.Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location), Path.GetRandomFileName());
}

to push all XF temp Assembly in the WebAPP Specific folder.

i let you know if this wiell solve my problem.. in 2 h, i know more.

Hi Lars,

 

This issue resolved in Xafari v14.2.x07.143, where Xafari.XF uses …\Users\User_Name\AppData\Local\Temp\Xafari folder.

 

For local solution to your problem (if you use Xafari version under v14.2.x07.143), you have to:
1)

    override next method at your WebApplication:
protected override string GetDcAssemblyFilePath()
{
return Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.UserProfile), "AppData\\Local\\Temp\\Xafari", this.ApplicationName, Path.GetRandomFileName());
}

or
if you want to push all generated assembly to WebApp local folder
2)

    use code as below
protected override string GetDcAssemblyFilePath()
{
 return Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "GeneratedAssembly", XafApplication.DcAssemblyFileName);
}
    Additionally actions:
    if you use impersonate=true you have to create windows user group with modify permission on GeneratedAssembly folder
    and have to add all users (so IUSR) in this group. If you use impersonate=false you have to set modify permission
    on GeneratedAssembly folder for user which used in AppPool.

 

I hope you find this information helpful.

Regards, Sasha.
