Its all about 

<pre><code>.Normalize(NormalizationForm.FormD)
</code></pre>

, probably EF does not knows how to handle this method. Remove it and test just with 

<pre><code>c.FullName.Contains("Café")
</code></pre>

------------------------------------------------- Added in 2015-01-30 --------------------------------------------------

So man, the unique solution i can think about is list before you do the where condition. This way the you can use the normalize once this will be handled by linq 2 objects. try: 

<pre><code>(from c in svcContext.ContactSet join a in svcContext.AccountSet
on c.ContactId equals a.PrimaryContactId.Id 
select new {a=a,c=c} ).ToList()
.Where(c=&gt;c.FullName.Normalize(NormalizationForm.FormD).Contains("Café"))
.Select( x=&gt; select new {
 account_name = x.a.Name,
 contact_name = x.c.LastName
 };)
</code></pre>

But that way can cause some overhead given that linq 2 obejects runs in application server memory, not in database server.

CRM's LINQ translator cannot handle the .Equals() method.

<pre><code>on c.ContactId equals a.PrimaryContactId.Id

Change the above line to below line.

<pre><code>on c.ContactId == a.PrimaryContactId.Id

blocks|key|362293|text|不能在LinQ上使用该函数，正确的查询方法是：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|362294|c.FullName+==+"someString"+or+c.FullName.equals("someString").|code-block|syntax|javascript|362295|这是因为您不能在左边的条件上使用函数或转换。您必须使用属性本身。|362296|您的查询如下：|362297|using+(ServiceContext+svcContext+=+new+ServiceContext(_serviceProxy))

You can't use that functions on LinQ-CRM, the correct way to do the query is:

<pre><code>c.FullName == "someString" or c.FullName.equals("someString").
</code></pre>

This is because you can't use functions or transformations on the left condition. You must use the attribute itself.

Your query will look like:

<pre><code>using (ServiceContext svcContext = new ServiceContext(_serviceProxy))
 {
 var query_where3 = from c in svcContext.ContactSet
 join a in svcContext.AccountSet
 on c.ContactId equals a.PrimaryContactId.Id
 where c.FullName == "Café" || c.FullName == "Cafe"
 select new
 {
 account_name = a.Name,
 contact_name = c.LastName
 };
}
</code></pre>

You can't really deal with the accents with Linq to SQL in general ... and you are even more limited with what you can do with Linq to CRM. You cant modify the DB; unless you don't care about being supported. Then you could do something like : MAD suggested and to a db alter. 

<code>ALTER TABLE Name ALTER COLUMN Name [varchar](100) COLLATE SQL_Latin1_General_CP1_CI_AI</code>

I personally would not recommend that. 

The best that I can come up with is getting the data as close as you can and filtering it from there inside a list or something similar. 
I have to do it all the time and it is a pain (and adds more overhead) but there is not really another workaround that I have found. 

<pre><code> //declare a dictionary 
 Dictionary&lt;string, string&gt; someDictionary = new Dictionary&lt;string, string&gt; ();


 using (ServiceContext svcContext = new ServiceContext(_serviceProxy))
 {
 var query_where3 = from c in svcContext.ContactSet
 join a in svcContext.AccountSet
 on c.ContactId equals a.PrimaryContactId.Id
 where c.FullName.Contains("Caf")
 select new
 {
 account_name = a.Name,
 contact_name = c.LastName
 };
}
//then
 foreach(var q in query_where3)
 {
 if(string.IsNullOrEmpty(account_name)==false &amp;&amp; string.IsNullOrEmpty(contact_name)==false)
 {
 someDictionary.Add(account_name, contact_name);
 }
 }
</code></pre>

<code>//then you can add the .Normalize(NormalizationForm.FormD) to your dictionary</code>

Hope that helped.

I 'm trying to do a search for a contact. For example value "Café " which is stored in the name field , but when I search like "cafe" does not return any record .

I tried to do the following

<pre><code>using (ServiceContext svcContext = new ServiceContext(_serviceProxy))
 {
 var query_where3 = from c in svcContext.ContactSet
 join a in svcContext.AccountSet
 on c.ContactId equals a.PrimaryContactId.Id
 where c.FullName.Normalize(NormalizationForm.FormD).Contains("Café")
 select new
 {
 account_name = a.Name,
 contact_name = c.LastName
 };
}
</code></pre>

and appear the Exception with message saying "Invalid 'where' condition. An entity member is invoking an invalid property or method"

"Invalid Where condition" when I try to search for a value that is accented ignoring accents in CRM 2011 with LINQ
