The NetTopologySuite SQL Server provider had a hard dependency on SqlDataReader.GetSqlBytes(), preventing custom DbDataReader implementations injected via interceptors from reading geometry data.

Changes

  • SqlServerGeometryTypeMapping.cs: Changed _getSqlBytes to use DbDataReader.GetFieldValue<SqlBytes>() instead of SqlDataReader.GetSqlBytes()
  • SqlServerGeometryTypeMappingTests.cs: Added test verifying the method works with DbDataReader base class

Technical Details

Before:

privatestaticreadonlyMethodInfo_getSqlBytes=typeof(SqlDataReader).GetRuntimeMethod(nameof(SqlDataReader.GetSqlBytes),[typeof(int)])!;

After:

privatestaticreadonlyMethodInfo_getSqlBytes=typeof(DbDataReader).GetRuntimeMethod(nameof(DbDataReader.GetFieldValue),[typeof(int)])!.MakeGenericMethod(typeof(SqlBytes));

This follows the pattern already used by SqliteGeometryTypeMapping and aligns with the base RelationalTypeMapping implementation. The change maintains full backwards compatibility since SqlDataReader inherits GetFieldValue<T>() from DbDataReader.

Problem

The Microsoft.EntityFrameworkCore.SqlServer.NetTopologySuite package currently has a hard dependency on SqlDataReader that prevents it from working with custom DbDataReader-derived classes injected via interceptors.

Current Issue

In src/EFCore.SqlServer.NTS/Storage/Internal/SqlServerGeometryTypeMapping.cs (lines 25-26 and 108-109):

privatestaticreadonlyMethodInfo_getSqlBytes=typeof(SqlDataReader).GetRuntimeMethod(nameof(SqlDataReader.GetSqlBytes),[typeof(int)])!;publicoverrideMethodInfoGetDataReaderMethod()=>_getSqlBytes;

This code specifically references SqlDataReader.GetSqlBytes(), which means any custom DbDataReader implementation from interceptors will fail when trying to read geometry data because:

  • Custom DbDataReader implementations won't have the GetSqlBytes method

Required Changes

Modify the SqlServerGeometryTypeMapping<TGeometry> class in src/EFCore.SqlServer.NTS/Storage/Internal/SqlServerGeometryTypeMapping.cs to work with DbDataReader instead of SqlDataReader:

  2. Update the _getSqlBytes field to reference the generic GetFieldValue method from DbDataReader

The solution should use:

This way, it will work with:

  • Any implementation that properly implements GetFieldValue<T>

Code Review Guidelines

The NetTopologySuite SQL Server provider had a hard dependency on SqlDataReader.GetSqlBytes(), preventing custom DbDataReader implementations injected via interceptors from reading geometry data.

Changes

  • SqlServerGeometryTypeMapping.cs: Changed _getSqlBytes to use DbDataReader.GetFieldValue<SqlBytes>() instead of SqlDataReader.GetSqlBytes()
  • SqlServerGeometryTypeMappingTests.cs: Added test verifying the method works with DbDataReader base class

Technical Details

Before:

privatestaticreadonlyMethodInfo_getSqlBytes=typeof(SqlDataReader).GetRuntimeMethod(nameof(SqlDataReader.GetSqlBytes),[typeof(int)])!;

After:

privatestaticreadonlyMethodInfo_getSqlBytes=typeof(DbDataReader).GetRuntimeMethod(nameof(DbDataReader.GetFieldValue),[typeof(int)])!.MakeGenericMethod(typeof(SqlBytes));

This follows the pattern already used by SqliteGeometryTypeMapping and aligns with the base RelationalTypeMapping implementation. The change maintains full backwards compatibility since SqlDataReader inherits GetFieldValue<T>() from DbDataReader.

Problem

The Microsoft.EntityFrameworkCore.SqlServer.NetTopologySuite package currently has a hard dependency on SqlDataReader that prevents it from working with custom DbDataReader-derived classes injected via interceptors.

Current Issue

In src/EFCore.SqlServer.NTS/Storage/Internal/SqlServerGeometryTypeMapping.cs (lines 25-26 and 108-109):

privatestaticreadonlyMethodInfo_getSqlBytes=typeof(SqlDataReader).GetRuntimeMethod(nameof(SqlDataReader.GetSqlBytes),[typeof(int)])!;publicoverrideMethodInfoGetDataReaderMethod()=>_getSqlBytes;

This code specifically references SqlDataReader.GetSqlBytes(), which means any custom DbDataReader implementation from interceptors will fail when trying to read geometry data because:

  • The method is looked up on SqlDataReader specifically (not DbDataReader)
  • Custom DbDataReader implementations won't have the GetSqlBytes method
  • Casting to SqlDataReader would fail for custom implementations

Required Changes

Modify the SqlServerGeometryTypeMapping<TGeometry> class in src/EFCore.SqlServer.NTS/Storage/Internal/SqlServerGeometryTypeMapping.cs to work with DbDataReader instead of SqlDataReader:

  1. Replace the SqlDataReader.GetSqlBytes method reference with DbDataReader.GetFieldValue<SqlBytes>
  2. Update the _getSqlBytes field to reference the generic GetFieldValue method from DbDataReader
  3. Ensure the GetDataReaderMethod() returns a method that works with any DbDataReader-derived class

The solution should use:

privatestaticreadonlyMethodInfo_getSqlBytes=typeof(DbDataReader).GetRuntimeMethod(nameof(DbDataReader.GetFieldValue),[typeof(int)])!.MakeGenericMethod(typeof(SqlBytes));

This way, it will work with:

  • Standard SqlDataReader
  • Custom DbDataReader-derived classes from interceptors
  • Any implementation that properly implements GetFieldValue<T>

Code Review Guidelines

  • Check the IsDeleted flag when retrieving entities from the database
  • Suggest removing code chunks that have been commented out
  • Ignore changes to any mortar directories as this is auto-generated code

Goal

Enable the NetTopologySuite SQL Server provider to work seamlessly with custom DbDataReader implementations, allowing users to:

  1. Use interceptors that inject custom DbDataReader-derived classes
  2. Build this modified branch locally
  3. Reference the DLL directly in their projects instead of the NuGet package

Files to Modify

  • src/EFCore.SqlServer.NTS/Storage/Internal/SqlServerGeometryTypeMapping.cs
    • Line 25-26: Update the _getSqlBytes field initialization
    • Ensure line 108-109 continues to work correctly with the new method reference
