Add database entity annotations for the EF framework using the T4 template

There is a workaround on the internet as follows:

But I tried. It's too much trouble, and once the EF is rebuilt and rebuilt.

Later I queried the information, can use the T4 template to solve this problem.

1. Download file getsummery.ttinclude, here I have provided, everyone to download: download 2. Unzip the files we downloaded and put the extracted files into the solution3. Modify the following app.config, add a connection string:

1. <add name= "myconn" connectionstring= "data source=.; Initial catalog=db;user id=sa;password=xxx; " providername="System.Data.SqlClient" />

4. Modifications model.tt, add code at the top location:

1. <#@ include file="getsummery.ttinclude" #>

5. (Insert class Comment, optionally add) insert above code fragment <#=codeStringGenerator.EntityClassOpening(entity)#> (around 28 lines)

1. <summary>
2. <#= gettablesummery (code. Escape (Entity) #>
3. </Summary>

6. (add field comment) in code snippet: <#=codeStringGenerator.Property(edmProperty)#>Above (76 rows or so) Insert:

1. <summary>
2. <#= getcolumnsummery (code. Escape (entity), code. Escape (edmproperty) #>
3. </Summary>

Note: The previous comment symbol///cannot be less

Here, basically done, to refresh your entity model EDMX file, you will find the field comments are automatically added.
