一直用pd生成实体类，今天试了下用vs生成实体类，网上很多资料，但大部分操作太繁琐，本人整理2步搞定
1、下载GetSummery.ttinclude，点击下载，并将其中的ConnectionStringName变量值site换成自己的数据库连接串，记得数据数连接串必须加 providerName="System.Data.SqlClient"，不加会报错：正在运行转换: System.ArgumentException: 应为“providerInvariantName”参数的非空字符串；
2、改.tt文件，直接搜索<#=codeStringGenerator.Property(edmProperty)#>，将此句前所有代码替换成以下代码：
<#@ template language="C#" debug="false" hostspecific="true"#>
<#@ include file="EF6.Utility.CS.ttinclude"#>
<#@ include file="GetSummery.ttinclude"#>
<#@ output extension=".cs"#>
<#
const string inputFile = @"Model1.edmx";
var textTransform = DynamicTextTransformation.Create(this);
var code = new CodeGenerationTools(this);
var ef = new MetadataTools(this);
var typeMapper = new TypeMapper(code, ef, textTransform.Errors);
var fileManager = EntityFrameworkTemplateFileManager.Create(this);
var itemCollection = new EdmMetadataLoader(textTransform.Host, textTransform.Errors).CreateEdmItemCollection(inputFile);
var codeStringGenerator = new CodeStringGenerator(code, typeMapper, ef);
if (!typeMapper.VerifyCaseInsensitiveTypeUniqueness(typeMapper.GetAllGlobalItems(itemCollection), inputFile))
{
return string.Empty;
}
WriteHeader(codeStringGenerator, fileManager);
foreach (var entity in typeMapper.GetItemsToGenerate<EntityType>(itemCollection))
{
fileManager.StartNewFile(entity.Name + ".cs");
BeginNamespace(code);

{
<#
var propertiesWithDefaultValues = typeMapper.GetPropertiesWithDefaultValues(entity);
var collectionNavigationProperties = typeMapper.GetCollectionNavigationProperties(entity);
var complexProperties = typeMapper.GetComplexProperties(entity);
if (propertiesWithDefaultValues.Any() || collectionNavigationProperties.Any() || complexProperties.Any())
{
#>

public <#=code.Escape(entity)#>()
{
<#
foreach (var edmProperty in propertiesWithDefaultValues)
{
#>
this.<#=code.Escape(edmProperty)#> = <#=typeMapper.CreateLiteral(edmProperty.DefaultValue)#>;
<#
}
foreach (var navigationProperty in collectionNavigationProperties)
{
#>
this.<#=code.Escape(navigationProperty)#> = new HashSet<<#=typeMapper.GetTypeName(navigationProperty.ToEndMember.GetEntityType())#>>();
<#
}
foreach (var complexProperty in complexProperties)
{
#>
this.<#=code.Escape(complexProperty)#> = new <#=typeMapper.GetTypeName(complexProperty.TypeUsage)#>();
<#
}
#>
}
<#
}
var simpleProperties = typeMapper.GetSimpleProperties(entity);
if (simpleProperties.Any())
{
foreach (var edmProperty in simpleProperties)
{
#>
/// <summary>
/// <#= getColumnSummery(code.Escape(entity),code.Escape(edmProperty)) #>
/// </summary>
<#=codeStringGenerator.Property(edmProperty)#>
......
刷新下.tt看实体类已经有注释了
