Hi,

I'm developing an application with Dynamics CRM SDK with Xrm in C# and ASP.NET to extract some information, and I have some problems with caching.

For example, If I obtain the price of a product that is 300, then I change it to 400, and then I reload it, I obtain 300. I don't know why is caching. If I go to IIS and stop my application,the Xrm connection it's reconnected and I obtain the right price of 400.

To fix it, I try to add this sentences in the HTML but it doesn't work.

If I restart IIS, it Works, so I think that Xrm is caching something, but I don't know how to fix it

Thanks

Hello Santiago,

Can you provide the part of the code where you call the CRM web service ?

Hi,

When you debug the application, are you making the calls to CRM again and it's returning the old value, or is it not making the call and the page is just refreshing?

Thanks,

Aiden

Hi Santiago, Thank you for reaching out.

Clement and Aiden on to it here. Depending on how you are calling the web service the connection will use cache data, like when using Service Context.

Hi Santiago,

you can use the function below to remove a CRM cache by entity.

public static void ClearCache(string entityName)

{

const string format = "adxdependency:crm:entity:{0}";

var dependency = string.Format(format, entityName).ToLower();

var cache = Microsoft.Xrm.Client.Caching.CacheManager.GetBaseCache();

cache.Remove(dependency);

}

msdn.microsoft.com/.../microsoft.xrm.client.caching.objectcachemanager.aspx

Thinks,

Youssef.

Hi,

I'm calling XrmServiceContext every time with the onload event. For example:

protected void Page_Load(object sender, EventArgs e)

{

var xrm = new XrmServiceContext("Xrm");

// Obtenemos las empresas del parque de Maquinaria y los Contactos

var PM = xrm.new_parquemaquinariaSet.OrderBy(i => i.new_Cliente).ToList();

var Contactos = xrm.ContactSet.OrderBy(i => i.ParentContactId).ToList();

foreach (var ParqueMaquinaria in PM)

{ }

}

Thanks

Hi,

I faced the same problem using simple connection. I added this to my web.config:

<services default="Xrm">

<add

name="Xrm"

type="Microsoft.Xrm.Client.Services.CachedOrganizationService, Microsoft.Xrm.Client"

serviceCacheName="Xrm"

instanceMode="PerInstance"/>

</services>

<serviceCache default="Xrm">

<add

name="Xrm"

type="Microsoft.Xrm.Client.Services.OrganizationServiceCache, Microsoft.Xrm.Client"

objectCacheName="Xrm"

cacheMode="Disabled"

returnMode="Cloned"

queryHashingEnabled="false" />

</serviceCache>

<objectCache default="Xrm">

<add

name="Xrm"

type="System.Runtime.Caching.MemoryCache, System.Runtime.Caching, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"

instanceMode="PerInstance"

absoluteExpiration=""

priority="Default"

outputCacheProfileName="Xrm"/>

</objectCache>

Hope it helps (did for me)!
