Dynamic CRM 2013学习笔记（三十）A proxy type with the name account has been defined by another assembly

在CRM中使用linq时，有时会报这个错误：

A proxy type with the name account has been defined by another assembly.

Current type: Account, MyAssembly, Version=1.0.0.4, Culture=neutral, PublicKeyToken=be9afbacb707a086,

Existing type: Account, CustomPages, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null

Parameter name: account”

网上一搜索，有人说解决很简单：

var connection = CrmConnection.Parse(connectionString);
connection.ProxyTypesAssembly = Assembly.GetExecutingAssembly();

再到项目里一看，发现就没有这个CrmConnection:

Uri orgServiceUri = new Uri(CRMServiceUrl + "/XRMServices/2011/Organization.svc");
            ClientCredentials credentials = new ClientCredentials();
            if (CRMAuthenticationType == "AD")
            {
                credentials.Windows.ClientCredential = new System.Net.NetworkCredential(CRMUserName, CRMUserPassword, CRMUserDomainName);
            }
            else if (CRMAuthenticationType == "ADFS")
            {
                credentials.UserName.UserName = CRMUserDomainName + "\\" + CRMUserName;
                credentials.UserName.Password = CRMUserPassword;
            }
            OrganizationServiceProxy crmServiceProxy = new OrganizationServiceProxy(orgServiceUri, null, credentials, null);
            crmService = (IOrganizationService)crmServiceProxy;

 

原来是用的OrganizationServiceProxy，于是把它改成OrganizationService，因为OrganizationService里面会用到这个CrmConnection：

ClientCredentials credentials = new ClientCredentials();
if (CRMAuthenticationType == "AD")
{
    credentials.Windows.ClientCredential = new System.Net.NetworkCredential(CRMUserName, CRMUserPassword, CRMUserDomainName);
}
else if (CRMAuthenticationType == "ADFS")
{
    credentials.UserName.UserName = CRMUserDomainName + "\\" + CRMUserName;
    credentials.UserName.Password = CRMUserPassword;
}
string server = string.Format("Url={0};Domain={1};Username={2};Password={2}", CRMServiceUrl, CRMUserDomainName, CRMUserName, CRMUserPassword);
var connection = CrmConnection.Parse(server);
connection.ProxyTypesAssembly = Assembly.GetExecutingAssembly();
connection.ClientCredentials = credentials;
m_CrmService = new OrganizationService(connection);
m_SvcContext = new ServiceContext(m_CrmService);

改完后，就不报这个错了。
