# Improvements to C# analysis
The following changes in version 1.26 affect C# analysis in all applications.
## New queries
| **Query** | **Tags** | **Purpose** |
|-----------------------------|-----------|--------------------------------------------------------------------|
## Changes to existing queries
| **Query** | **Expected impact** | **Change** |
|------------------------------|------------------------|-----------------------------------|
| Weak encryption: Insufficient key size (`cs/insufficient-key-size`) | More results | The required key size has been increased from 1024 to 2048. |
## Removal of old queries
## Changes to code extraction
* Partial method bodies are extracted. Previously, partial method bodies were skipped completely.
* Inferring the lengths of implicitely sized arrays is fixed. Previously, multidimensional arrays were always extracted with the same length for
each dimension. With the fix, the array sizes `2` and `1` are extracted for `new int[,]{{1},{2}}`. Previously `2` and `2` were extracted.
* The extractor is now assembly-insensitive by default. This means that two entities with the same
fully-qualified name are now mapped to the same entity in the resulting database, regardless of
whether they belong to different assemblies. Assembly sensitivity can be reenabled by passing
`--assemblysensitivetrap` to the extractor.
## Changes to libraries
## Changes to autobuilder
## Changes to tooling support
* The Abstract Syntax Tree of C# files can be printed in Visual Studio Code.
